Very high pressure HELP!!

[ALGESIDE]

thanks pooldoc ill send some pics, i did a little bit more research and i found my pump is a 1.5hp, but i was looking at the TOTAL hp. but i did talk to a friend that had the same problem with his shasta pool, " they are both 20 year old" the pop up assembally is not a care taker but a shasta pop up cleaning system. he said he removed the internals of the cleaning system gears and all, and reattached the dome with noting inside and his pressure went from 30psi to 12psi and he uses a vaccum plugged into skimmer to clean the pool, my only question is since the water returns to the pool threw the popups, will it still be able to do so or will i have to take out the popups and install screens? thanks for any input at all!!

Welcome to the forum.
Do you have normal sidewall returns in addition to the floor popups and a valve to select where the return water goes? Filter size aside, 30-35 psi is probably in the totally blocked range. Whatever you do don't run the pump for more than a few minutes with pressures this high. If the flow is totally blocked you can raise the temperature of the water in the pump high enough to warp the case.

there is no switching valve, the return goes from the filter strait into the shasta cleaner " the floor cleaner " its 20 year old. when ever the gears inside switch to a diffrent set of pop ups the pressure drops to 22psi then goes right back up to 30. i believe the restriction is in the floor cleaner control head. also some pop ups where replaced, could the outlet holes on the floor pop ups be to small causing the restriction?

I really don't know anything about that cleaning system. Hopefully someone else has some ideas.
