Hi - We just bought a home with an in-ground pool in the fall and I am starting up the pool equipment for the spring. I do not have any experience with pool equipment. The previous owner left me with some notes but I think something is wrong.
The filter is a Hayward sand filter - 30". The model is 711 which I think is older. Much of the labeling is coming off.
The pump is a Hayward 1 1/2 HP
There is also an auxiliary pump use to run a little pool cleaning robot
The pump starts up fine and the skimmer sucks in water pretty well when it first starts. Water is moving through the system. I can see it in the pump and can see/feel it coming out the return. Within a few minutes the pressure reduces. it does not completely stop but the pressure is no longer enough to pull in the water effectively and clean the pool.
I think the pressure gauge is broken as it does not move at all when turned on/off. And it has a tiny water leak.
The glass sight at the top is empty (should it have water in it when set to "filter" or only backwash?)
I have lubed the o-ring with a silicon lubricant.
The skimmer basket and filter basket are clean
I used a wire to see if any gunk was on the pump impeller.
I went through these applicable low pressure checks
Any suggestions are appreciated. I am not sure if this is something I can fix myself, if I need to call a pro to fix it or if I'm looking at replacing the pump or filter?
