The link above shows a picture of my system. The pipe with the clear
coupling that is circled is leaking.
Is it normal for this pipe to be full considering we have had a pretty
Is this pipe incoming or outgoing?
I plan on calling in help to a plumber, I just wanted to get familiar
with the system before I do so.
P.S. If this post is a duplicate, please forgive me.
That looks like the check valve. It lets water go up but not down So
after it runs the pipe above it is still full and could leak. You want to
keep the value there, it keeps water from outside from coming in and
flooding your basement.
That looks like a check valve which is there to keep water from flowing
back into the sump pump hole after the pump shuts off. Normally it
would have water in the line from above the valve to the point where it
exists the house and begins it's downward journey to wherever it ends.
So, it could be leaking without the pump having run recently, however
there should only be a gallon or so of water to leak out.
Can you tell what's actually leaking? It's most likely the clamps and
you may be able to fix it yourself quite easily. Worst case, you can
just take off the whole check valve assembly and bring it to a plumbing
supply or home center and they could give you what you need to fix it.
Probably save at least $100.
As others have mentioned it is a check valve which consists of a rubber
flapper that allows water to pump out and then seal from the weight of
the water in the pipe once the pump shuts off. It is normal for water
to be in the pipe above as the rubber seals quite well from the weight
of the water on top. If the pipe is full of water, then the check
valve sounds like it is working just fine. Check for cracks in the
valve body and consider removing the check valve and reclamping it on
the PVC pipe to reseal it. If all else fails just pick up a new check
valve at your local home improvement store for about 10 bucks and youre
good to go.
As others have said its called a check valve. Yes, its normal to have water
above it. Its for discharging water from your sump.
Now, considering a dry spring, why would you have water in the pipe? Easy -
I can see from the picture that you also have a water softener. Every time
the water softener 'recharges' it will dump some water into your sump hole.
You sump pump will pump it out when it gets full enough.
Its an easy fix, no need to call a plumber. There are band clamps above and
below the check valve. Just use a screwdriver and loosen them. Remove
everything between the top clamp and the bottom clam. Take it all to Lowes
or Home depot or your helpful hardware man. Ask him for ... Just give him
what you removed, tell him you want a new everything, same size. Then just
put it all back the way it came off.
FYI - There will be some water above the valve. It will pour out when you
remove the old valve. Just have a few towels and a bucket handy. Shouldn't
be too much water, certainly not enough to fill a bucket.
a small leak in the check valve is not such a bad thing.
If the valve were perfect, the water would just sit there in the pipe
for a long long time. It can cause freeze problems outside
If the valve leaks a little, that water will slowly empty back into the
sump and be absorbed into the ground.
