I recently replaced my old Liberty sump pump with this model and notice a gurgling after the check valve closes, is that normal?

Do you by chance have a second/backup sump in the mix? Like perhaps a water powered sump?

hard to day where the "gurgling" is coming from, but i would think its related to the check valve, and that you didn;t hear it before or theres something preventing the check valve from seating properly

I'm not a plumber, but I would suspect either the placement of the check valve or the valve itself. The valve should be screwed into the pump housing - not somewhere up the line. If that's okay, there might be something keeping the valve from closing properly - dirt or a faulty valve. Does the gurgling stop right away? Is water backflowing after the pump turns off?

I had the same thing also. The check valve i got from lowes was not good. There is one on here, I think its called the Quiet check Valve. Its clear and white. I added that and i done even hear my pump run. I had to go down to listen and make sure it worked. No thud or gurgling. Great addon. Also its clear so you can see what the check valve is doing. I love my liberty pump with the valve i was walking about.

I haven't experienced any noise after the pump stops and the check valve closes. It sounds like the valve is leaking a little bit and allowing water to drain back.

Not normal! No motor noise, maybe just a hum. Unless the motor is not stationed firmly and is maybe vibrating, I would return. Mine is so quiet, I sometimes forget it is there until I here running water!

my pump is quiet however sometimes it will touch the top sides of the lid and make noise. I am just mindful of that and will move it accordingly.

I have not had this problem with either pump I installed. Possibly water is not staying in the line and the gaskets are getting dried out or your intake and overboard discharge are clogged and water is not flowing smoothly through the system or (if you have one) your holding tank is full so there is no place for the water to pump into...

It could be the pump rotors are beginning to rust and expand like I mentioned in my review. When this happens, they start scraping and making noise, and the water circulates less. There is not much you can do about it.

My pump runs very quiet especially compared to my old pump. I don't think there is noise after releasing the float for about 15 seconds.

Hello. The filter will start making a gurgling noise when you need to change it. They are small and seem to need changing frequently. If it is a new filter you also may want to add water to tank to stop the noise. Filter should slide in the grooves and all the way down. I don't think it's suppose to be partially pulled out

Our pump works perfectly and is very quiet. It sounds as though you may have a faulty pump.

Yes that is normal. That is happening because the diaphragm is pulsating. If the hose stops doing that, then you should check to see if the diaphragm has a tear in it.

Nope...that's not normal. There must be a leak. Do you hear any hissing? If so, try to locate the source. It might just be the valve where it attaches to the tire. Mine shuts off when it reaches a little over 100 psi...it's supposed to do that. It must be cycling because of a leak. I suppose you could remove the cover to inspect. Might just have a fitting that needs to be tightened. Good luck.

I did not shake mine so I cant tell if it makes noise. Previous answer sounds right. If in doubt, call the factory. I am very pleased with the filter. You might want to buy a brass fitting for the water connnection. I dont like the plastic connector. I had a brass fitting from my old filter that worked perfectly.

As with all backup systems of any kind, you should occasionally check its operation. I check mine about every 6 months, especially in early spring when most of my water starts to come in to the sump pump. All I do is unplug the main sump pump and wait to make sure the basepump kicks on. If there is no water coming into the sump, I have to run a garden hose into the sump to test it. The first year I had it, one of my tests failed because I must have not clamped the float down tight enough and the float got caught on the side of the sump wall and wouldn't raise but that was my fault for not tightening down the clamp enough. Thats why its always good to test any backup, no matter what it is.

That is odd. Sometimes I get a gurgling sound but that is it. Should be silent. Remember to run filtered water through it. Might want to hit up seller.

It is the permeate pump causing the noise, the motor makes noise and then you hear the pressurized flow run through the lines. I bought this unit because I thought I needed a permeate pump being on a well, and my water pressure is perfectly fine. It actually caused too much pressure and made my faucet leak which was the main reason for my return. I now have the exact unit without a permeate pump and I couldn't be happier. If your water pressure is around 60PSI I would return this and get the non permeate unit.

A couple of things come to mind. Is the panel dirty and need to be wiped? The pump may be working but the intake could be clogged and needs to be cleaned out? Is the pump submersed fully? I found my pump not working (but I can't see mine) because it was above the water line, adding water solved it.

It's barely a hum from the main floor of my house. Replacing the check valve surprisingly made mine significantly quieter as well. The cheap original sump pump was easily twice as loud and when the pump cycle would end stopped with a thud sound. The thud sound stayed until I replaced the check valve (with a Zoeller). Now, you have to really listen for it from the main floor. From within the basement you know when it runs but it's not intrusive. I've helped five neighbors install this and they all love it as well (or pretend to, at least).

It's normal at first fill up, I was concerned about the noise also but after about 2 hrs the tank filled up and the noise stopped. Follow the manual it's very descriptive. After the tank fills up you have to let all the water out (about 5 min). When it fills up again the water is safe to drink and there's no noise.Good luck.
