I don't quite understand. Can you elaborate further?

I ordered a new valve, and it was WAY larger than the old one. The one I purchased is a 2" valve. I thought I was ordering the correct size based on the OD of the union threads. Wrong! I am having some real difficulty finding this valve in the same size. It's a bit confusing. When the...

I just took the valve out, and measured the opening force at the center of the valve. It measured 3/4 lb. I just ordered a new one rated at 1/2 lb. That's a good point. I believe it is about 15 psi when set to the spa. The pump motor is out of commission, so I can't check it right.

At this point, I am not sure. When they reference 1/2 lb, is that 1/2 psi, or 1/2 lb force to open the valve?

Jim, These are very good questions. The check valve appears to require the same pressure to open it, and holding it open. I don't feel any sticking. The filter was recently cleaned. I disassemble the Pentair filter for cleaning, rather than back flushing. That way I can make sure it is...

I can't find the receipt now, but I believe it was this one. https://www.amazon.com/Valterra-200-CU20-Swing-Spring-Combination/dp/B00B95UUJQ/ref=sr_1_14?keywords=pool+check+valve&sr=8-14

I have a Pentair Superflo 1.5 pump. It gives me about 11 psi pressure when the filter is clean.

Hi Jim, Yes, it won't fill and spill into the pool. I put a new check valve in, but it did not correct the situation. The valve will work occasionally when the filter is clean. The valve is definitely not in backwards. Here is the other strange behavior. If I set the output valve to "spa"...

I put a new valve in, and it didn't help unfortunately.

Here you go. The pipe in the middle going to the valve is from the hot water heater. The pipe on the right side of the valve and going down goes to the pool. The pipe on the left side of the valve and going down goes to the spa. The swing gate check valve in the middle flows from the pool...

I appreciate the tip on the Neptune motor replacement. I have a service factor motor now that is 1.1. The Neptune motors look much more programmable than the Century units. I'm going to do some shopping for the Neptune NPTQ165. Thank you!

Thank you for the link. That give me a better idea of how to set the schedule up.

The bearings on my Pentair Superflo 1.5 h.p. pump starting getting noisy, so I ordered new motor bearings. While waiting for parts, the pump failed to start one day, and I could tell it was going into thermal cycling. I immediately cut power to the pump. Lucky me, I took the pump apart, and...

On the outlet side of the pump is a T-fitting with a swing valve that bleeds some water going to the pool and sends it to the spa. The problem is the swing valve doesn't open reliably, and then no water goes to the spa. The swing valve acts as a check valve for times you have the t-valve set...
