For a new install did you add a check valve before it? Does this pump have enough output pressure to open a swing type check valve?

David, It is a 1/2" brass check valve that is installed on the discharge side of the pump.It operates just fine. Down stream of the check valve the plumbers installed a 1/2" ball valve that is opened 1/2 way to throttle the volume of hot water that it circulates. It's great. Allan Lynch

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.

There are terminals that you plug into. If you are replacing a bad pump the old pump will have the same set-up. Check your old pump to see if there is a plug running to it.

Yes, it does have a check valve. I've used several of these converting forklift tanks over.

Since mine is installed, the main valve has been remained open. If your spray head is leaking, my guess is that you have less than perfect parts and/or the installation was not done properly.

I don't have an answer for you on that one. I didn't try what you did. The pump worked fine, we are using it as a spare.

Probably some fittings and a reverse flow check valve. Depends on your existing system. I installed mine with minimal additional items as my system was previously set up for a pressure tank (different kind).

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 purchased the valve but did not do the work, so I do not know the answer to your question.

There was no direct adjuster on the pump itself. I ran the output thru the tubing into a small flow-switch I bought at Lowe's that has an adjuster. I just barely cracked it open and got all the way down to drip level and it worked great. You can try it on either end to see which works best for you with the pump pushing into the adjuster or pulling from it. The valves are very cheap and work wonders and makes you wonder why they weren't added to the pump in the first place. Good luck.

you will need 3 threaded adapters, 1 for in which will be the size you have, 1 out, 1 vent, the pvc pipe and fittings dependent on where and how you have to run the pvc, I used a check valve because of the height of my run as it keeps from cycling the pump so much. The install was SIMPLE the pipe, plug it in and that is pretty much all there is.

just installed it. VERY quiet and it seems to working great. Make sure you wire it before plumbing it, small area inside the pump housing to connect the wires and it is easier to do so when you can move the pump.

Did you try adjusting the switch shut-off screw on the end of the pump. This adjusts the pressure the pump will maintain. My guess is it needs to be turned clockwise if this is the problem. There should be a manual with the unit that has troubleshooting guide.

I installed this pump and check valve to a existing system. I replaced the check valve with a new one and it didn't come with the pump. We used her tank. She uses the water for her yard like you and the last time I talked to her she was very happy with the pump. The check valve I bought was the TC2505LF 1-1/4-Inch Check Valve. It was a little more expensive then another one but just wanted to do this once and be done.

A pressure gauge should have been included. I would contact Amazon and let them know the gauge was missing so they could send you one.

No, you will need to install a check valve in the discharge line; something like Campbell Mfg Llc 1.5" Quietsump Chk Valve B-0823-15C. If you do a google search for Liberty Pumps 287, you will find the liberty pumps website and you can review the engineering specifications as well as installation instructions in PDF format. The installation instructions are printed and included with the pump.

It has a built in check valve, although not a very good one. Use a rubber splice when connecting to the tee, in case you ever have to replace the check valve.
