What is the "Manual Pressure Equalization Valve" and when/why would I need to use it?

It's like a Pelican case....basically, the case fully seals all air inside, causing pressure buildup occasionally. The valve, when rotated, releases that pressure so it doesn't damage anything inside. At least that's how I understand it...I could be completely wrong...but I know anytime I've taken my case on an airplane I have to use the valve.

Atmospheric pressure changes with altitude. If you fly with the case (even in a pressurized cabin) the air inside the case will expand and create a vacuume effect that could prevent you from opening the case unless you use a pry tool. Sticking a small piece of paper on the edge when closing will also prevent this from happening in cases without this feature.

No, its a manual handle. the pressure gauge is on the other t fitting. it did increase pressure from 15 to 20. pool co said that's fine.

There is an adjustment valve on the handle. It allows for pressure control also.

It's called a presta valve. I bought a hand pump from walmart that's interchangeable between the two types. It was like 20 bucks. I bet Amazon sells them.

Yes...you don't want to bleed off pressure unless unless you are replacing seals or valve parts...BUT, you don't want to leave it cocked.

It appears to be a compression fitting. As long as the water pressure is constant, the selected water setting remains static to your choice. Therefore when pressure is dropped, the lack of compression retracts the "selector" to the default setting.

I am not an expert. I have mine hooked up to the Natural Gas company line that has a meter on it. I think it reduces the pressure.

It's a standard valve stem (Schrader valve, I believe it's called) connector used on auto wheels. You can fill it with any tire inflator that is connected a source of compressed air. It's located on the brass assembly that connect the hose, air control valve, and gauge to the tank.

Push the valve to one side to release pressure. Not sure if that was designed like that but it works

You cannot adjust to a desired pressure with this device. It regulates to a fixed value and shows you the reading so you are sure of it.

This works for me. I'm in the same situation as you have just described. Most electronic timers out there require certain amount of water pressure to assists the opening/closing of the valve, but this particular timer, Toro 53746, does not require any pressure at all to function. Hope this helps.

The bottom valve is used to adjust water temperature. the other controls operate the overhead, the hand spray and the jets. the amount you open or close them controls the flow/pressure.Each can be operated independently or all can work at once. Obviously ,if using all at the same time, the pressure is less than if you operated one only.Hope this helps.

Hi, We purchased this valve through Amazon. American Standard R110SS Pressure Balance Rough Valve Body Only with Screwdriver Stops. It installed easily and works well.

As far as I know, you may only use a GROHE Pressure Balance Valve trim with this valve. You must be careful not to purchase a GROHFLEX valve trim, as it will not work with this valve either.

You should need nothing else. If for some reason you wish to control the flow you may want a inline valve. I didn't use one and every thing is fine.

I didn't buy the check valve for a pump such as you appear to be using. What is the purpose of the pump and why are you concerned about back-flow or back-flush?

A pressure relief valve, which was not included and I can't find one locally, so I asked the company for advise, but so far they have NOT answered.
