Loss Of Pressure In The Return Line
I have a brand new Hayward 1.5hp pump and just installed a new multiport valve head. All but one of the hoses are new as well. Also changed sand and checked fingers. Problem is that when I turn the pump on, I get great pressure out of the return line. Pressure gauge on filter is at 11.. as the pressure gauge moves up (like 19) the pressure on the return losses pressure? After I back wash and pressure is restored. Pool is very green. Will everything be ok once the pool clears up or do I have another problem? Thanks for your help. Thanks for the question Check the pump impeller as it may be clooged with debris. Turn off the pump and remove the pump basket. Stick your fingers into the suction hole in the pump strainer housing. If the seal is broken or wobbles, you'll need to fix or replace it. Be sure the skimmer and pump baskets are clean. The problem could be a dirty or clogged filter, a blocked return line, or a valve that is partially or fully shut off. Is the pump making any strange noises? If so, the impeller may be clogged. This will cause it to rotate at a lower speed. Is your pump a variable speed pump and the tension is ok? Can any air be seen through the lid? Check the gasket around the lid and replace it if it's squashed or worn out. You could also try this: Turn the pump off and take the lid off. Insert your garden hose in the hole above the basket (this is the pipe where water comes into the pump while it's on). Wrap a large piece of cloth around the hose to cover the hole to prevent a loss in pressure. Obviously don't jam the cloth into the hole so you can't get it out. All you're doing is trying to create a seal the best you can. Turn the hose on and open one of the valves and close the other one (if applicable). With more than one valve you will alternate between a closed on and an open one. Notice if there's anything out of this "backflushing" that clears the line. If you see that the line isn't clogged, try opening another valve. You'll notice water coming out of the skimmer, for instance. You can also check the diffuser on the pump motor. These tend to go quickly if you're not careful Also, your algae could be building up in the filter quickly and back washing is the only way to get rid of it.
