Should I install 2 valves on the sump pump piping ?
I have relatively new setup and the valve is located all the way down by the sump pump as it should to prevent the back flow....however, I am a bit annoyed by the sound of the water flowing back along the pipes..... I have about 6 feet horizontal pipe to the exterior wall and another 7 or 8 feet down to the pit.
All are 1.5 inch
Would it be advisable to install another one-way valve right on top of the pipe ?
I know this is purely "cosmetic" since there is nothing strange about water flowing down an 8ft vertical pipe and my only objective is making it silent (yes...I am very anal when it comes to noises and sounds LOL).... just worry that two valves along the path my impact the pump ability to work efficiently,
Any input ?

If the check valve at the pump was working properly there wouldn't be any water coming back to the pit.
A check valve won't help if the water noise you hear is from water draining away from the pump.

Agree with PJmax. I suppose if you have a horizontal section that is sloped wrong you might get some flow back toward the pump. Make sure the horizontal section is sloped from high at the pump to lower at the outlet outside the wall. Are you sure you're not just hearing the water in the pipe when the pump stops draining to the outside? Not much you can do about that besides insulating the pipe to muffle the noise.

the horizontal section is pretty much leveled.....that's why I get a bit of that water going backwards and down.... I guess I will just install a second valve at the very top of the vertical pipe.
Thanks!
Thanks!

One problem of water falling back down the outlet pipe and into the pit is that this water detracts from the pit volume remaining for new ground water and then the pump has to cycle on more frequently.

Allan - the water doesn't drain back into the pit..... There is a valve right before the pump....the water only travels back from the top of the pipe to the valve....it all stays inside the pipe until the next cycle.

So long as the check valve right before the pump is holding, after the pump shuts off the vertical pipe is still completely full of water so no additional water will travel back from the top of the pipe to make noise.
Occasionally the check valve gets held ajar by a bit of sediment. Then the water in the vertical part of the pipe and maybe some from the nearly horizontal part higher up (if the pitch going out is not sufficient) will come back down into the pit.
Depending on the kind of sediment, that may or may not be pumped up and away on the next cycle. You may need to dismantle the outlet pipe and clean out the check valve by hand.

thanks Allan - that's an excellent point and I appreciate it.
I was thinking that as the water is expelled from the pipe, once the pump shuts off, then a bit of air gets in and that's why I have sound of water travelling back down the vertical pipe....
Your explanation makes sense and if the pipe were full of water - I shouldn't be hearing any water travelling back....
