Yes, weak flows come out of the heads, but not strong enough to pop them up. I have a small diameter valve that diverts spillover from pool side to the spa. When I turn the return valve fully to pool, the filter pressure goes up from 22 psi to 28 psi, weak outflow from heads, medium flow from...

Update: Tested outflow of 5-valve. All have strong flow, thus there must be blockage in all 5 pipes. But the 25 ft auger is not long enough, I ran it through all 5 pipes but wasn’t able to get through any of them. Just bought a 50 ft auger on Amazon, hope this one could be enough.

Finally figured out the water level is now too low that the skimmer suction is unable to suck from the main drain hole. It can only drain to this level, the rest of it must use a separate pump.

Read the article and watched a few videos, it seems the main drain will not drain the pool completely if it’s plumped to the skimmer. Somehow, when I removed the short pipe it sucked water from the main drain for a few hours, but stopped when the water line dropped about 1 ft. After then the...

Thank you so much for your help! Yes, I cleaned the strainer.

Thanks! Yes, I cleaned the strainer.

The two holes in skimmer are not covered. I guess the reason it sucked air was because I have a short pipe connecting the suction hole to the cleaner’s pipe, thus it raises the suction hole up and couldn’t suck from the main pool drain. I removed that short pipe and now the pool drain works! I...

Thank you so much. Yes, 2 drains in the spa and 1 in the deepest end of the pool. 2 holes in the skimmer. When water level drop below the skimmer, it sucks a lot of air into it. What should I do to the 2 skimmer holes to allow the pool drain to work? Thank you so much for your help!

Yes, when suction is from the pool, it’s the skimmer. I have a cleaner connected to the skimmer suction as the in-floor is not working. The return valve pool side goes to the IFCS. And it does have a small diameter pipe to send some spillover to SPA. If I switch it to SPA, it will bypass the...

My heads are old too. Would the new one fit in the same hole? Thanks!

I have two other valves to control the flow near the skimmer. Somehow that picture was not accepted by the server. The valve on the right is return switch between pool and spa, left is suction from skimmer or bottom drain. Now they are both on pool side. The three switches are heater, pump, and...

Thank you so much for your help. I took the pictures yesterday at night. I just took more with good lighting. I actually opened the housing and checked all the gears and they all rotate normally. However, as you said jet is small and should result in higher psi, I completely agree, but in my...

Yes, I did clean the dome and inside, also replaced all o-rings. It was leaking before. Now no more leaking, but heads still not popping up.

Thanks for your reply! 1, the 5-valve gauge is 5-25 psi, 5 when returns to SPA, 25 when returns to pool. 2, Pentair FNS 60 DE filter, Pentair Whisperflo High performance pump 1 HP. 3, Yes, I cleaned the filter thoroughly, though after cleaning the pressure went up 5 psi, instead of going down.

Dear folks, I bought the house with a nice pool, but as a first time pool owner, I had no idea what everything was supposed to be. It turned out the entire in-floor cleaning system was not functioning. 0 out of the 15 pop up head works. 1 was missing. I bought a new one, but still couldn’t...
