Campbell Mfg Llc 2" Quietsewage Chk Valve B-0823-20C Well Supply Accessories

Using in a basement sump pit with grinder pump. Before installing, my pump was running for long periods of time (it typically only runs for 5-10 seconds at a time to empty out the sump pit). I wasn't sure if a) the pump was bad, b) the check valve was bad (my original valve was not a 'see through' design) or c) my pipe had a clog somewhere.Turns out it was my old check valve that was bad. The install was easy (basic PVC cutting and gluing) and it comes with PVC attachments that let you unscrew out the valve if needed. This might be handy if I have to replace someday -- can just screw another one in without having to cut or glue.This valve lets huge amounts of flow through, and best of all it is COMPLETELY quiet. If I have problems in the future then being able to see the water flow will let me know if water is flowing to help with the diagnosis. No more water hammer when it shuts off, you don't hear it at all. Why didn't I buy this years ago?I've had it installed for about a month, so I can't yet speak to it's longevity but I see no reason it shouldn't last a long time. Completely satisfied.UPDATE - 15 months later and working perfectly. It's one of those things that you 'enjoy' every time it works. Sounds silly for a check flow valve but it's quiet and works so well. If you need a valve you must buy this. I paid full price for mine and have no relationship with the manufacturer!

Our sump setup previously had a cast iron backflow valve, with rubber "fernco" couplings. The cast iron valve failed, causing excessive vibration, which led to the rubber couplings slipping off the pipe. Needless to say, I urgently sought a better solution.This is it!Easy to install onto standard PVC pipe, with standard PVC primer and cement.When I first installed and tested, there was a slow leak. Realized that the o-ring in one of the mating faces had shifted out of place when I slid the whole fitting into place.Easily remedied, and now I have no more leaks!I also immediately noticed how much quieter this unit is compared to the old cast iron valve and rubber couplings. The cast iron resonated, and the rubber vibrated every time the sump pump kicked on. Now, it's about as loud as running the sink or a quiet toilet flush. Much better, especially because the sump is installed next to a couple bedrooms.This is great!

The media could not be loaded. About five years ago I went on a quest to silence a sump pump. I was tired of the water hammer that that followed every triggering of the pump. During and after any considerable rain there was a predictable hum and thump from the floor as the sump cistern filled and was emptied out in the yard. I did all of the recommended steps. I got rid of as many 90° turns as possible, I moved the piping away from joists then fixed it in place with thin foam insulating it from the wall and the clamps holding it. The last thing I did was install one of these valves. I can honestly say I don't know if the sump is still operational unless I'm standing staring at it when it runs. The clear body allows you to see the valve move.Cut to three weeks ago when we utilized new space in the basement. A family member slept in the newly renovated bedroom and made comment about the thump the sewage pump makes Everytime the cistern fills. When I ordered this I didn't expect it to be clear. When I received it I almost sent it back. I've been staring at the last three weekends. I finally gave in and installed. It was simple to place because of a ball valve I'd installed above the original. Unplug the pump, shut off the top-side valve, wrap the whole thing in paper towels and remove the old valve. I made a single cut on the bottom stretch of pipe to make the proper amount of room. A little primer and adhesive was used to set the end connectors in place and screw the flanges down to the valve housing. It's silent. The noise you hear in the video is predominately water from a toilet flush and sink running into the cistern to trigger the pump.If you have a noisy sump or sewage pump, don't hesitate to find one of these. That spring holding against the pump's water pressure will save your sanity.

Great check valve that allows me to watch the operaation of two individualy installed sump pumps set at different levels Pirmary and Backup.

Works brilliantly. I wish they had an opaque version. I'm using it for my basement sewage pump and I really don't want to see what's passing through it. Plan to keep it covered. I'm using a 1½ " version on the sump pump for the past 4 years - no issues (knock on wood!)Careful when cementing the coupler piece to the PVC pipe. When I inserted the pipe into it with both pieces cleaned and cemented - the pipe nearly completely popped back out instantly. I was able to immediately push the pipe back in and give it the required twist and hold the pieces together with pressure to fuse the pieces. So make sure that you hold both pieces under pressure from 30secs to a min to give the pieces time to fuse. Otherwise it will likely pop out and you'll end up with a weak or leaky connection.Docked a star for their non-existant customer service. No way to reach them. Which is a bummer!
