The main house shutoff valve should have been swapped out to a ball valve & re-located, to be situated immediately after the city shutoff valve (prior to the pressure reduction valve).
Depends on code for state and local municipality
You can use a small piece of white bread stuffed in the pipe to hold the water back until you get everything soldered, then just forget about it and the bread will break apart naturally and go down stream when you turn water back on.
Did that hold water? That soldering job was off the hook. It was on the sidewalk too LOL.
great video, no filler BS and straight to the point!
Thanks!
I would of replaced the shut off valve & the water faucet to avoid any leaks or failure...It avoids problems down the road ...
Sounds good!
Why not rebuild as much of the whole section offline as you can? And replace the rotary knob with a nice new lever shut-off valve?
Sounds good to me.
This is how a video is done quick and to the point.
Thanks!
Your The jack of all trades sparky ⚡️
Thanks! Have a great day!
Do you have a video of doing the maintenance repair kit? I have one, and am having a hard time figuring out exactly what tool to get the hex but off the top to access the internals to swap out...
Excellent. What is the life expectansy of these valves? I heard it was 5 - 9 years. Why?
best video I could find on this subject, thank you!!
thorough and detailed - thanks for sharing this.
Did you skip a step at 7:56 in this video? After applying the flux, don't you have to heat the pipe and apply solder to sweat the joints?
Yes, that's correct.
Sparky, if my valve is 4” wide, how wide do I need to cut the pipe? With hardware and washers, would it be 5”?
Thank you for the plumbing share sir. I think
your outdoors which has me puzzled, unless
this is a tropical island where it never freezes.
How is this prudent or code legal if in USA where every state is subject to a freeze if rare.
Never seen a pipe through a side walk. As we
have learned when buying older homes one is
often chasing bad carpentry & plumbing. Not
sure why waterline was not buried under sidewalk, then into structure. For young home
shoppers a good home inspector will point out all the code compliant issues. Best of luck
to you sir.
Thanks! I live in San Diego where we don't have enough freezing temps to make a difference.
In San Diego CA, all older homes have the water pressure reducing valves outside. It never gets below 45 😅
We have this set up in FL too.
Very helpful video. Save me lots of time. Thank you so much!! Gracias.
You're welcome!
Thanks for posting this, very helpful and descriptive.
My pleasure, thanks!
Good little job Wild Bill ...Well presented ...
Thanks Eddy! Have a great day!
stupid question, regulators work vertical as well as horizontal ?
Yes, they work just fine either way.
What about deburring copper pipe before soldering?
Yes, that is very important.
@@SparkyChannel because you put fitting directly to cut pipe th-cam.com/video/1yDS6xD4Ppc/w-d-xo.htmlm16s
Does the PRV go after the shutoff valve or before ? Just wondering if it really matters
They usually have one after the PRV valve where I live, so it goes the street shutoff, interior shutoff, PRV, and another at the water heater.
Great video! Thank you.
Glad you liked it!
Thank you so much. This is great.
Should we put Teflon tape on the pressure regulating valve as well or are the washers good enough?
Washers good enough. Teflon wouldn’t help
It is a compression type connection where Teflon would be unnecessary
Love videos! Keep them coming!!
Thanks!
would deburring the inside of your cuts be recommended?
Highly recommend
Necessary
like how much do you charge to do that job?
Good job! With all these video, you are the one explained end to end easily to understand. I have the exact same model. Where did you buy?
Thanks! I got that one at Home Depot. I don't know if they still carry it though. I have an Amazon link for it in the description.
if i had shop vac, would that work to suck the water out ???
Yes, that will work.
About to install one myself, do the union threads on the regulator itself need teflon tape?
No they have a gasket
No Teflon if gasket
Can you use shark bite for this? I’m afraid to solder
yes
Good job bless you
GBY as well!
Good video Dparky.
Thanks Gary!
Shouldn't it be installed horizontal?
na, their manual says horizontal or vertical is fine.
what about a thermal expansion tank, is that necessary with this pressure reducer?
Yes it is
@@joshbarron4415 can you explain why? Just trying to understand.
@@ko6128 A pressure reducing valve (PRV) also acts as a check valve. When the cold water feeding the water heater expands due to temperature, it doesn’t have anywhere to go other than out the T&P relief valve which is why they drip when no expansion tank is installed. The expansion tank gives the water somewhere to expand to without opening the temperature and pressure relief valve and dripping
@@joshbarron4415 ok. So with a tankless water heater, the hot water is flowing out a fixture. Doesn’t that path give the pressure somewhere to go? Thru the open fixture.
@@ko6128 Yes it does but only when it is open. The most common complaint is people find their temperature and pressure relief valve valve dripping in the morning because the heater was heating at night and the increase pressure had no where to go bc there wasn’t an expansion tank and no one was awake to use any of the fixtures.
what is the expected lifespan of these? thanks!
Perhaps 15-20 years although there are rebuild kits which will keep them running even longer. It also depends on how hard your water is.
@@SparkyChannel thanks!
Well Done!
Thanks Derek!
Good job 👍👌
Thaqnks Cesar!
That was dangerously high lol
True.
Thanks a lot, next time can we see you solder
LOL! Thanks!
Wow 10 bar langsung ke kran kran di rumah pasti menjerit kencang ruh kran nya bunyi maksudnya kang pompa/ plumbing pasti tau lah
untung pakai pipa Cooper seperti buat AC 100bar an aja masih bisa
Coba pipa plastik PVC jebol dah semua kare a maximal nya 8bar kecuali yang upvc warna abu abu 10 bar masih aman
I enjoyed your video. But.. your soldering looks like you dropped the solder pot out of a helicopter on the pipe!
Can this increase the pressure higher than what you were getting before installing the valve?
No! Typically they are factory set around 50 psi and top out at 75 psi depending on which one you have
@@stevetheplumberbreeding7402 Thanks for the response. If this type of valve can't increase pressure, how can I increase pressure in my home?
@@harleyb-ham266 install a booster pump
no new main valve installed before the WPRV? and why is the old valve still there? boooooooooo. great install
That original 1960 shut off valve still works. LOL! Thanks Dave!
@@SparkyChannel Hi Bill. But if you replace that old shut off with a quarter turn ball valve, you'll make sure that you don't need to worry about the seat washer or packing going bad on that old shut off.
Also, did you ream the cut ends of the copper line before soldering to remove any burrs and taper the ends to reduce turbulence in the line?
Hope you and your family stay safe and well.
@@ccadama and use less solder.
What will happen if the regulator happens to be installed backwards?
I won't work correctly.
Extremely low water pressure and heavily water hammering!
Double the PSI of course
Universal paradox. We all end up back in 1985! ⏰ flip it around unless you have access to a DeLorean
How much should i pay for a job like this?
$250
In my area it’s 500 +parts
full price
@@pablopantaleon1499 good one!
The straw trick is cute lol just use a vacuum
Great tip, thanks!
or a spray nozzle from a spray bottle
Large turkey Baster would work very well too
👍👍👍💋
Thanks!
I know it all depends but want some advice and input. Is it okay to install a PRV in place of a gate valve. Would there be any harm in doing that. Saves me work and digging. I live in a house with foundation. Please feel free to give me advice. Tes my gate valve is on the ground about 5 feet from the main city shut off
No, your house needs a valve so that you can turn off the water to the house. It would be bad to eliminate it. Use both the PRV and a good quality valve.
@SparkyChannel
Honestly, what's the purpose of the gate valve if it's only like 5 feet away from the main shut off valve to the entire house. Could I just not use the valve I could care less for that valve. I can use the main shutoff valve for that
Thanks for sharing, Great Video!
Our pleasure!
