My neighbour had an inch or so water come into his basement last week. Called me over to check his sump pump. It was running but the float came off. Had the sump pump replaced under warranty that afternoon. That night more hurricane Debbie heavy rain. Three feet of water in the basement and now he discovers that he has a backflow valve. And it is not working. Just wondering. Can sewer rats get up through that pipe.

fantastic Thank you ,now I know what it is and how to clean it also know why my basement flooded. Great Video Thank You

Very useful video, thank you

Ok. Thanks. I will try it. I hope it works.

How do you get a manual hand crank valve unstuck. Mine will not turn clockwise or counter clockwise?

We just hear pounding

The water running made it difficult to hear the voice

Looking to install one soon, your Video inspired me, thank you Sir,, wish more people were like you.

don't forget a vacuum, very handy.

definitely a good video if you have one of these. Mine are 32 years old and I never needed them or inspected them. Now I know what to look for when I try to snake out my drain (first slow flow in 32 years). Watch out for splooge! The talking while chiseling concrete part provided comic relief. Aboot time, too, when you work sewers...

Sewer specialist found a chunk of grease building up at flap 。 he recommended not use it. One month later I remove it because it causes problem.

Thanks, very informative.

What are the best Settings I have a e8

I've got a question if you could please answer. Should the check valve assembly be installed at an angle where the valve flap rests on the outgoing direction, preventing inflow? I have a check valve flap that was installed for it to be straight up and down. It has failed several times since installation. I replace it once a year and have started cleaning it every time there is rain coming. What else do I need to do to prevent it from failing?

Can you recommend a few models / Name Brands that have a good reputation for reliability? Thank you….very good video

Hi...can it detect those leaking from pipe concealed in concrete wall?

We just did a jet cleaning at a house and got stuck… ‘o I must tell you, the council install a non return valve in our line’. We have a sewer nozzle and half inch pipe stuck in the line AND it is 2.5m deep with no access!! We need to do some serious excavation and it is between walls! I just hate moments like this. It maybe a good item, BUT it was seriously installed wrong. My 2c. We in South Africa

It is amazing how fast you can detect water leak with such simple equipment. Right here in Singapore, our Government boards in charge of housing and the town council, still uses dye flood test to find the source of water leak. It has been 6 months since they investigated my corridor ceiling leaks and (1) still failed to get the responsible party to fix the toilet where the leak comes from and (2) just yesterday an inspection at my house still cannot find the leak on the spot. No they don't use the simple equipment you are using. I am getting my own infrared thermal to help them. Such incompetence. Yes, here in Singapore, and they are Government organizations.

For all the people out there who love to design devices using Arduino, here's a great opportunity. So what I see here, is that it would be easy to place a water sensor into this box (drill hole in top, insert sensor, seal the hole with silicone) and set it near the top or perhaps even 1/2 way down. Then, have the Arduino use a wireless transmitter so that one can monitor on a receiver Arduino, the condition of backflow system. If the water starts to rise (to the point of the sensor), the a signal can be sent to the receiver and perhaps even a BEEP warning sound can alert to a problem well before the problem gets really bad. I'm going to use a different unit, because this one I just don't trust. I see so many videos and while this box looks great and works great, the way the flap lays on the bottom is just asking for trouble. As we said, "stuff" builds up under the flat and acts like glue, holding the flap down. I'm liking the other style where it's basically a pass through and the flap hangs from top down. Sure, it still needs cleaning, but appears much easier to clean AND is very easy to replace the flap.

More bureaucratic bull shit.....Here's what happens to these devices: 1. Someone runs a snake through it (not knowing it's there) and breaks the flapper off it's hinges...causing chronic back-ups. 2. There's a rubber "lid" seal inside some of these devices and it rots into pieces that fall down and cause the flapper to get stuck...causing chronic back-ups. 3. Once the rubber seal is gone it allows roots to enter the system...... causing chronic back-ups. Somewhat counter productive right? I have removed about 5 of these devices (including my house and my rental's) and zero issues now. I'm a new construction plumber and have installed 1000's of these....none have ever done their actual intended job....kinda like air-gaps, water savers, anti-siphon valves, double-check valves and liquid plumber... none have ever done their actual intended job. But it creates jobs for those who make them.... HELP! (bureaucratic bull shit)

Thank you very much for this video, my wife and I just moved into a beautiful little house for the first time last year and we have one of these, which is actually in an extra bedroom in our basement. We've had a clog 2 times already..........2.5 /3ft going towards the city side. I'm going to access it at least once a week to make sure everything is working fine and their are no clogs

83 baby

I appreciate you sharing this video as I decide if I want to install this as an upgrade in my new build.

Oh man...I didn't know about backwater valve though this machine is installed in my house. It's been 12 years, no maintenance is done. Now I am worried about it and I have to clean. Thanks for uploading this video.

So how is the thermal camera seeing behind plastic vapor barrier? I thought a therm can only sees surface temp

Wow great find! Kind of scary! U just answered a big concern I had about the thermal imaging cam being able to see behind a plastic vapor barrier! Thank you. I'm buying one!

Cool, does it need to be a Flir brand? Could 200 thermal imagers see where the leak is in the walls? Any affordable thermal imaging cameras you can recommend to see hidden leaks? Thanks.

I absolutely would not buy that design it’s made to fail! The hinge should be at the top out of the muck so that water leaving the home continuously move the valve,And doesn’t cement it in with all the junk that goes through it.

What's the brand of that thermo cam ?

Would this stop mice getting in through sewer?

Whats with a video with your lead lamp on?

Instead of using a small shovel, try a shop vac first

Thanks for the advice. Is there a problem if we keep the valve lifted for a few minutes to clean underneath ? Will the waste water keep flowing during this time ?

Flir thanx China for pipelines etc products Not sayin all products..

Thank you for the very informative video! You mentioned concrete flow and I am wondering if you might have some advice: I came across a valve cap that is blocked by the retainer, compressed with some concrete behind it (pushing inward, directly overtop of the cap). Would have any recommendations to safely break up the concrete in order to access this valve assembly? A friend commended to perforate the concrete using masonry bit (would have to be drilling through the retainer and likely also take a chunk out of this compressed side...). Any advice is highly appreciated, thanks!!

heavier dutier, Ha Ha Ha!

Would could you do a video of water of different temperature interacts with itself . Hot bath then turn on cold water what’s that look like

Name.of this Camera using?

What is the name of that camera?

Interesting! I'm kind of surprised that this would be the system on a new house where you are. I live in Chicago and here we have overhead plumbing that is mandated by building code for houses built starting in the70's. My house was built in 58 and has surprisingly also has overhead to prevent backups. Is that not common in Canada? I wonder why they haven't gone to this method?

Yup, its amazing what you can find with a thermal camera.

Thank you Sir. After watching your video, I was able to fix the problem which is a clogged back flow sewer valve. You saved me $150. Thanks again

Naaah No worries. Flush the toilet poop goes away. Its amazing. No worries.

It’s great to see local home inspector videos.

That happened to my toilets

Very nice that theu covered it with cement. .

Thank you!! Thank you!! Thank you!!! Amzingly awesome video. I wish i had seen it and known this can cause be so helpful. But thank you so very much for this in depth tutorial!!

es ist schon eine feine sache so eine thermografie kamera, man kann sehr viel damit entdecken! www.rutengaenger-und-mehr.de/

What model camera is this?

About how much money you going to charge for your time with your infrared camera
