Hello. There is a tiny rubber ball inside the valve that often gets worn. When it gets worn, the water flows back into the pump as soon as it shuts off.

Hi there, I checked my three way connectors, both of them ( I have in both bathrooms ) came with 3/8" not 7/8". Maybe try to check in Home depot or Lowe's. My husband told me it's came with that 3/8" adapter.

I wish I could answer your question. So far, I have tried every search, been to Lowe's and Ace (They usually have every answer) and so far I am coming up with nothing. I bought the Blue Source at the C-co and didn't realize I had a 3" valve and that the unit wouldn't fit until halfway through the install. I'm not giving up yet though.

This item has a 3/4" flange on the back side. I didn't want anything larger on the flange.

I spent months trying to find a valve that behaved like a hydraulic valve used on pipelines. Was dismayed to discover that shower valves were required to allow a small amount of flow to continue in order to keep the water the same temperature when it is turned back on. To avoid cold water shock I suppose.Finally had to buy a less attractive valve from an industrial supply store that actually performed as I wanted, meaning full off or full divert.

I would use 3/8". You will need to purchase a barbed tube fitting 3/8" tube x 1/2 npt

I'm not sure. It could have been something my son did. But, I will say, it is definitely worth a try especially with Amazon's great return policies. We still use it, you just have to get used to how to play it with the valve.

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 believe that the 3/8 is usually the buckle size used. There is a size difference in 550 & 450 paracord!!

No, its an 1 1/4" to 1 1/2" discharge. A 3/4 " hose would create too much back pressure. Also all sump pumps need to a check valve on them to guard against any backflow back flow.

I searced on Amazon for the the phrase "3/8 to 1/4 water connector" and came up with multiple results. I think what you are looking for is this product with ASIN # B008214L0Y. Here is the URL to the product.MettleAir 120-CB 3/8" NPT Female to 1/4" NPT Male Brass Pipe Adaptor/Adapter Straight Reducer/Reducing Coupling Male to FemaleIf this product is not what you are looking for, you can try going to your local hardware store like Home Depot or Lowes, and ask the people working there.

Instead of removing you can drain the backflow preventer. In my opinion, it was easier to remove than drain.

I don't know what you mean about the check valve...what you see in the picture is what you get...It works perfect....

Not quite sure as the valve has never been a problem. I have had problems with the lid releasing pressure around the perimeter since I've owned it. Sent it back once now the company wants nothing to do with it. Sorry! Rjl

It's a three way valve!!It's not a check valve, but I guess you could use it with a secondary discharge pipe so you can manually switch the location of the discharge.

I don't care about 3/4". The thing works great. I bought a cheaper one and put up with it for years that leaked at the joints. This one doesn't leak. Delta makes a good product.
