Here is the typical Multiport valve on most Sand Filters. This is another thing that could cause problems with the sand filter and effect filtration. Here I show you how to take the multiport valve top off and check the Spider Gasket or Spoke. If it is damaged or coming unglued it will cause dirt to leak back into the pool or out the backwash valve.
Another telltale sign that the Spider Gasket is bad is water leaking out of the backwash pipe when the filter is running. Basically to change the Spider Gasket you will need to scrape it out with a screwdriver - make sure you get all the pieces out and don't gouge the plastic it sits in. Use one of the two adhesives I list in the video to secure the Spider Gasket back on the Multiport valve and don't tur nthe handle or turn the pol on for 24 hours.
If you notice water leaking out of the top of the handle and it is very hard to turn -chances are the o-ring on the handle got jammed into the O-ring or the O-ring went bad and is torn. At that point it may be time for a new Multiport valve but some people have had success changing out the O-ring in the spring -it is not easy to do.

I learned more from this guy than the other 10 videos on the same subject I watched. He does not sound like James Earl Jones but his sand filter videos are A+
That is exactly what I was thinking. Ours just went bad and needed some information and this guy is very helpful and easy to follow along with.
Thanks very much for the time taken to create this very helpful video.
Glad I watched this, as in my case water is not leaking but spewing from the top like Niagara Falls - so guess I'll just replace the whole head assembly. Thanks for the help, the last part of your son jumping in made me laugh as both my boys use to do that when they were that age ;)
Great video. I wanted to comment on that inflatable ring you son was playing with. I'm no helicopter parent or paranoid freak but I saw a kid flip over on one of those things and couldn't right himself...and the lad was very athletic....I just wanted to coment on those things...we didn't have stuff like that when we were kids and I witnessed it myself and don't allow them in the pool...just noodles and rafts and water wings....but all of our kids know how to swim now....thanks again... hope u didn't think my comment was strange.
Thanks - that is his reward for helping me out ;)
LOVE the ending! Thanks for sharing.
I just watched this video because I was having the same exact issue with the sand filters at work he just saved my ass
👍
Thank you. You got straight to the point and it was very helpful.
All of the lateral looked in good condition I didn't notice nothing different from the rest. I'm starting to leaning more on the spider gasket. My supplier has the top valve for the T-240BP1 but they don't carry just the gasket. The more I talk to others in the profession the more they tell me it's more likely the gasket that's either twisted or starting to wear out. But if you know where I can get the gasket I would appreciate it. I have tried looking online but they only have it for the T-240BP2. Thank you for responding.
Hi I replaced my spider gasket and spring is not broken but only springs back upwards when on recirculate. Do you know why please?
Good trouble shoot vid. Solved my issue :)
Good Information. I have a Hayward Variflo SP714 and when I back wash and put it back to normal, there is water still coming out of the backwash part. Could this be the spider gasket. please confirm ifyou can
Yes, sounds like the spider gasket. Change the complete valve or the spider gasket and you will be fine. I will swap out the complete valve if the handle is unusually stiff. If everything works fine then just do the spider gasket.
Can you give me some other symptoms I would be seeing while using 'backwash' 'filter' or any other seeing if my Multiport valve gasket was leaking?
I just replaced my Pentair spider gasket and spring assembly because my backwash line was wasting water in filter mode. I came back out the next afternoon and it seems that the water is still coming out of the backwash line. What else could the problem be?
Please tell me how do you i get the water drained out of the valve to get it dry to install the spider gasket
Hi, I put my multiport valve in the 'closed' position for a few seconds, and the pump made a crackling sound. Turned it off again, put it back on 'filter' and it worked for a while but very loud. Have been struggling to get it going again since, it seems to be humming.. Any suggestions would be great, thanks.
I just changed the sand for a new customer of mine. When I first ran the system I saw debris and sand coming out. So, I suggested to them to replace the sand. Now that I have replace the sand there's no more sand but whatever I vacuum does come out from the return side. The pool doesn't look hazy but could it be that I need to change the multiport valve. The o ring for the multi port looks good and I did lubed it.
It sounds like something is amiss with the multi-port valve. When the filter pressure increases when you vacuum that spider gasket might be expanding in there. This is more typical of a push/pull backwash valve but it can happen with the multi-port. How did the laterals look when you changed the sand?
It's possible that one could be leaking. Maybe test it with some DE to see if it comes out of the return line without the vacuum attached. Not a common problem as a lateral leak you would see sand also and not just the stuff you are vacuuming up.
So I just got a new Intex Sand filter 16in. It said that you should backwash and then rinse when first installing which I did. Then I noticed sand flowing back into the pool. So I tried the process again. Only this time it is stuck on backwash. What should I do?? I’m desperate lol
Hey You did a video on the very issue I'm facing, Oh sir! If Karma is real you've gotta be stacking chips! I just took over my father's pool maintenance at his house. His Parkinson's has progressed to the point where he can't vaccum anymore and I'm pool system is very inefficient! How he's maintained it this long with such a wounded setup. Thanks Again
Sounds like you have your work cut out. Helping your Dad is really a cool thing to do. 👍
I am having issues with my valve filtration is not working out all
unfortunately my valve is old and crcked and the replacement is the newer Hayward SP0714T which has different piping layout
when u seal it with glue , can you remove the screw . It would not be sealed forever.
I watched this video and it was nice but I'm not getting any leaks on the port but the handle is loose do you have a suggestion to fix that. Having air bubbles coming out into the pool. Thank you
It could be a small crack in that area. I suggest replacing the top part.
@@SPL before i order the part. Do you have play in the handle at all when set to any of the 6 things
awesome awesome video. Thank you
I removed my eco kleen filter valve amd the gasket was gummy and had to buy a new one, the pool store guy moved the position and I forgot what position it was in when I took it off. What can I do?
Maybe see if there are schematics online
Did this account ever upgrade to a carttridge filter
Great videos. Thank you for sharing..
Hello. Thank you for making these videos. I just changed the sand in my Hayward and replaced the whole valve unit at the same time. Filtering works good. Recirculation works good. Both with normal pressure (about 12). However when I backwash or rinse it barely trickles out when before it would gush out in the same volume and pressure as it did when filtering. Waste works well, which means there isnt any blockage in the backwash line. Any idea why the pressure is so low in backwash and rinse??
Is it the same exact valve unit as your old one?
yes. same model number. rinse has more flow but barely. Backwash is hardly anything. just installed 2 days ago. There is a hissing sound from valve when backwash is on. Maybe the sand tank needs more water?
Do you drain the filter or shut off external valves to prevent pool or hot-tub water from coming back up into housing once you 'pop the top'?
No need.
My multi port is sta rite and doesn't have a spider gasket. It looks like an adhesive. It has been leaking from the backwash but now it won't even prime. Can I use some type of adhesive to replace the non spider gasket?
+Marilyn stevens It should have one. Sounds like air is now getting into the system. Can you read the valve model #?
thanks, that was informative.
If the spider gasket has failed could it also leak down the return line bypassing the sand?
It's possible that port is open.
The last few times that I have cleaned out my strainer basket and have my multiport valve in the closed position, I am getting water coming back into my strainer basket area and slowly overflowing it. Does this sound like a spider gasket issue?
sounds like it.
Could you tell me why and where did you use the glue? i could not see an actual break in the video. I am having that problem and need to find out why the pump all of a sudden after a backwash, leaks the pool water out in filter mode. I placed it into backwash to clean out the sand came home and the pool had drained down pass the skimmer.
So water is leaking out of the filter from the backwash pipe? Are you saying enough is leaking to drain down the pool? If so the entire multiport valve could be bad and not just the spider gasket on the bottom. Spider Gasket keeps each chamber separate so a small trickle type leak means that the spider gasket is bad. This sounds like a bigger leak.
Swimming Pool Tips, Reviews & How To -MrDgvb1 Over the course of 4-5 hours. Either that all my neighbors kids (problem lately) may have help it along. Because I only found it leaking slowly enough to begin the process of filling up the backwash tubing.
Diamondgirl King Sounds like they put it in backwash mode just for some kicks. Kids...
G'day Mate and greetings from "Down-under". I backwashed my pool a few days ago and noticed, the next day after my kreepy krawley had been operating during the night that my water level had dropped. I checked later in the evening and made a mark of the water level and the next day, after the KK had been operating as usual, the water level had again dropped. I can only consider that some sand may have found its way into a valve, (possibly the rinse valve) and allowed water to escape through to waste.
Have you any ideas? If so, how can I fix it? Thankyou.
Probably their is a leak in the Multiport valve. I assume it goes into your drain and you can't visually see the water leaking while the pool is running - You will have to open up the Multi-port valve and check the Spider Gasket. It could be worn out causing water to leak out the backwash in filter mode.
question asked
is it possible to just purchase the base of the filter directional valve if the ports have spider cracks all the way around on every port?
It's cheaper to buy the whole unit from my experience.
I have a new Hayward 180T. Started leaking after a month out of the backwash. Pulled the diverter and two small 1/4” break/deforms in the gasket. Ordered an aftermarket gasket because Hayward now glues in the gasket and doesn’t sell just a gasket. Comes in in 3 days so I’m going to put a ball valve on the waste line to stop the leak for now. Think There will be a problem with a ball valve on the waste?
No, everyone does that. You are good.
@@SPL Thanks! Installed valve today, no problems.
suppose you don't take a photo or mark where the lever is and it gets moved. How can you get it back to the proper spot?
That is the same question I have. I don't feel like having to pull it apart. My backwash setting is where the filter setting should be. I was thinking about relabeling or just getting a new label plate and having it turned 180 degrees
You don't mention relieving pressure before starting on this valve. Is that necessary?
No, not necessary.
What will happen to the multiport valve if i didn't off the pump and just switch the handle from backwash to filter and when i switch on to normal operation, the water from the tank keep rushing out of the waste pipe to the floor trap. Is it due to valve damaged, please advice.
+Alex Huang Could be a damaged spider gasket inside. It is highly recommended that you turn the handle with the pool off.
I am getting de in my pool. Noticed 2 screws very loose and others not very tight. Will that release de?
Typically no. But maybe the spider gasket inside is bad.
@@SPL it looked ok. The de only came back when i added back in after cleaning grids. I added slowly and only the amount in the manual. 6lbs. Not much came back after i changed the oring inside the filter at top pipe. Then tightened down those 8 screws that where all loose. So can you expect a little de back in pool when you're adding in after cleaning?
I was wondering, would this filter work with a hot tub? I am being given one and was thinking of rigging it up.
Cartridge is preferred. Better micron and bacteria filtration.
Hoping you can help. What would cause water to backup through my skimmer? My basket won't fill completely. I've checked, and there are no leaks that I can find. Thank you.
Air getting into the filter tank. What type of pump do you have - brand?
It's a Hayward. My husband changed the pump cap gasket, and the top gasket on the sand filter (per the pool store's recommendation), but it didn't fix the problem.
How do I remove a spider gasket that was OVER glued? It wont come out.I have tried with a small screw driver and went along all the edges....Is there any adhesive remove I can use or will it damage the plastic housing?
Pretty tough to do. So in your case the spider gasket is not part of the multi-valve?
Apparently they sometimes melt/fuse together from the heat of the sun is what I was told by a parts/service guy. He said just keep scraping at it until it comes out. Well I finally got it out.It was NO EASY JOB.. IT took about 3 agonizing hours ..HOLY COW.. Don't want to have to do that again... What a huge pain in the butt!
hi i have a pool w a hayward sand filter. the pool had algae i treated and shocked when vacuuming the pool the remaining algae clouded up back in the spa no sand in pool or spa so i don't believe i have a broken lateral is this a channeling issue ?
Did you vacuum in waste mode? A little odd.
no i was in filter mode
Probably just overloaded the filter and some of the algae dust came out the return lines. Better to vacuum in waste mode in the future.
Hey when I put it on filter it's not on filter because it's draining the pool like if it was on back wash or waste mode
+Towelyey Spider gasket is probably damaged.
We replaced the efile assembly on our multiport valve (couldn't find just the spider gasket). Now the handle won't turn. Suggestions?
You replaced the complete top portion? Could be a defective unit. Had that happen before.
I have a pool that has an old pump motor, and old filter sand system. After a few hours of it running strong, it then starts to barely blow any water out of the filter into the pool. I replaced the pump and the sand, after a few hours it does the same thing. I backwash, rinse and put it back to normal operation. It will work for a few hours and then barely have any circulation again. To note the motor never cuts off on the new pump. I have a very slight leak from the multi valve port ring to lock it into place but I didn’t think that would be my issue. Anyone have any thoughts?
The air coming in could be the issue.
I had replaced a cracked handle of my Hayward Multiport Valve, I discovered that my filter setting is now backwash setting and the original backwash setting is filtered setting. Is it possible that I could just relabel or put a new label plate with the 180-degree setting discrepancy?
I think that should work - your the first with this issue so let me know if it works for you.
Ok, I will Thanks for getting back to me so quickly! I definitely didn't want to pull it all apart again
Thank you
Hello, We have a Multiport Valve of Praher Ocean 159447. Each time, we use the backwash function, and put it back to normal, it seems to work normal. But after a few hours or even after a day, we notice that the water, flushes slowly away throught the backwash flow. Could this be the spring which operates the handle? When we open the valve, what should we look at, to find the fault? Thank you in advance for any advice, Kind regards, Marlene
Probably the spider gasket on the bottom of the multi-port valve.
Thank you for you're free and gentle advice ! We live in Belgium (Europe) and the company who built our pool, doesn't care about us anymore :(. When the pool was finished, after 4 months, we noticed two bumps under the liner. The pool is built with isomo blocks, which are filled up with concrete. The pool cover resides in the pool, behind a false wall. This wall is fitted on to the side walls, and my guess is, that the person who put in the liner, added some cement to the false wall fittings, and that didn't dry enough. The pool builder says we had to report the problem while they were still building. But how could we, we saw the problem only after 4 months. The pool builder said he couldn't care less... So any issue we now have regarding the installation, we're on our own. Luckily there'se someone like you!
Thanks !
OMG! That sounds horrible! I hope you posted a negative review so that other prospective customers don't go through such shotty work.
Sand is coming out from my filter pipe can u provide some suggestions
Maybe a broken manifold. Maybe have a pool service company come look at it.
my pool is releasing water to our outside drain when we turn the pump on in the filter setting
Bad spider gasket inside not sealing off the filter port.
looks like you got alignment wrong when refitting although may be cam angle
Ah but then you correct it
Mine is stuck on filter and won't turn to any other option, I want it to turn to waste but it won't, any ideas?
saadi saade You can try to force it but that may cause it to start to leak water. The spring is won out in the handle. I suggest finding the part and model # of your valve and just installing a new one. It is pretty easy to do. Just remove all of the screws and insert the new one in. Around $80-$110
My multi port handle keeps getting gravel I'm it, making it unable to move. Everytime I vacuum pool, even when I have it on waste....help I've taken it apart now 3 times..
Maybe try adding a leaf canister to your vacuum hose to prevent debris from getting in there.
@@SPL Thank you for the tip.
I have a Hayward pro series sand filter. it works great while its running but the minute I turn off it flushes the water out of the pump/filter and basket back into the pool. I then have to re prime it to get it sucking again. is this just a bad check valve in the valve body?
Bad check valve. I assume the check valve is right in front of the pump? They good bad. What type is it? Some need to be completely re-plumbed while others you can get away with just changing the gate part.
could a bad multiport valve cause this?
mike ross If air is getting into the filter it could push the water out back down through the pump and down the pipes. Possible. Do you hear air in the filter when it turns off?
yes
its actualy a Sparco filter(not hayward) does hayward parts fit this brand?
I have water pouring from my backwash pipe when the Multiport valve is set on filter. When I put the setting on waste the water stops pouring out. I just bought a new Multiport valve thinking the spider gasket was messed up...and the new one is doing the same...Please, what am I doing wrong! (I have a Hayward pump and filter).
probably didn't put the head in the right position. same thing I did. I'm still trying to find out how to line it up. It worked when I moved lever to wrong position.
Yes the same with me. I have the backwash in the filter position too and I also had to "guess" the other valve positions, being everything is off by 180 degrees. It has been a nightmare.
Was that soap in the valve? Looks very sudsy.
I filmed two videos at once. One before was the filter degreaser. Thought no one would notice ;)
My filter started leaking from the waste side. Capped it now the bubble window started spewing.
Maybe a bad spider gasket.
@@SPL I didn’t know that the waste window screws on and off. It was loose. Glad I figured it out.
Thanks Man
Thanks! you have been very helpful.
For some reason my multi port is wasting my pool no matter what setting I am on. Even when I switch it filter it starts wasting the pool. I had a pool company out here to fix a pressure problem and he changed the spider gasket and the lid gasket. Ever since then it will only shoot water out like its wasting the pool. Anyone have any ideas?
+denice119 It could be that the spider gasket is still leaking or a defect of the unit itself. A Mickey-Mouse quick fix is to go to Home Depot and by a ball valve to attach to the 2" or 1.5" backwash pipe and close the valve. This will prevent water leaking out. I have this on a couple of accounts and it is an effective stop gap. Usually no gluing is needed as it is not under any water pressure. Just stick it on and close the valve. Just get the non-threaded type.

wont water shoot out the top of the filter once you remove the top
Jason Smith Not with the filter off.
Jason Smith just turn it off man :) try my filter troubleshooting guide here - simplepooltips.com/swimming-pool-filter-problems-solutions/ , so you dont have such questions in the future ;)
very helping
Can you tell me where online I can find parts for my 7 port Multiport Haywood thingamajig...Lol
It depends on the model number on top - if you can read it still -hopefully. Just get that number and Google it for a list of stores that sell it.
Thanks
what about if no water comes out when using backwash /rinse ?
cheers
Dan Sin Probably a bad spider gasket.
my sand filter is leaking from the bottom
Only thing on the bottom is usually a drain plug. That has an o-ring in it. They go bad over time.
Hello great vids .I have a problem with my Sand Filter, can't figure it out, I am getting no pressure showing on the gauge when the pump and filter are running in filter or normal mode, i also do not see water in the glass that is attached to the sand filter.The water has good flow, the pump sucks it into the skimmer then into the filter and returns it to the pool with excellent flow but it shows no pressure on the filter gauge,the gauge is new,, when i backwash it the glass on the filter fills with dirty water, when i rinse it ,,the glass fills with water but like i said when i run it in normal of filter mode i see no water in the glass, and i see no pressure on the pressure gauge ,also the return is sending some sand back into the pool.Thanks
Canadian Guitar Hack Possibly a bad spider gasket. Take off the multi-port valve and inspect it
Swimming Pool Tips, Reviews & How To -MrDgvb1 Thanks for the reply i will check that out,but would this be causing sand to to sent into the pool from the filter?
Swimming Pool Tips, Reviews & How To -MrDgvb1 1 more question to ask ,if i just want to circulate the water,will it bypass the sand filter? i just want to get the water moving around,or will some sand still end up in the pool.Thanks for the help
Canadian Guitar Hack Sand can leak in with a bad spider gasket in some cases. You can run it on recirculate and that will circulate the water and bypass the filter.
Swimming Pool Tips, Reviews & How To -MrDgvb1 Thanks for the advice,it's much appreciated,,,,,,have a great day.
When i refill my hottub dirt sand comes right bk in after draining n backwashing?
Have you tried leaving it in rinse mode for a minute after backwashing it? Maybe the spider gasket is bad inside the multiport valve.
1:26 Whi Is There So Much Soap Bubbles/Foam????
can the multi-port get clogged with debris.????
Not usually. It is more likely before the multi-port valve in the line.
right on brother thank you so much my pool is starting to look a little better
Mine is backwashing on filter and vice versa. None of the settings are correct. Can these be put on in wrong position?
Yes. Maybe the top was put on backwards.
@@SPL could you tell me the correct positioning please?
whenever i vacuum my pool dirt comes out from the other side of the pool is it because of the spider or the laterals?
Depends. If it is Sand it is probably the Laterals. If it is dirt then the spider gasket.
Leslie B you too
