am I getting nowhere fast. I kindly hope this room of pool gurus can enlighten me on my quest to create a healthy pool. I took vinyl cover off the pool that was basically hanging in the pool all winter (Long Island NY) and it was green like this font and smelled like fish. I put in 9 bags of shock and 1 gallon of algae killer. and it began to get lighter. I also pulled out 2 garbage pails of leaves and assorted bugs.
Here are the problems I have encountered that I am confused about.
1- I turned on the sand filter in filter mode to test and it was running at 45 psi immediately so I shut it down only to notice that the psi in the off position was reading 27 psi. My 1st question is this a broken gauge or is it calibrated to begin at 27 psi? The gauge can only go up to 45 psi on the dial.
2- I then put the unit into backwash to lower the pressure by doing a cleaning and when I began to backwash, once the pump primed and the water was moving nicely in the unit the backwash began to spit out of the hole on the unit label "waste". I turned off the motor and attached a garden hose to the sand pump and began the backwash function again. This time the backwash was coming out in a solid flow through the garden hose and I left it one for about 2 minutes. I turned the pump off and then went to the other side of my pool fence and notice a bubbling of the grass due to water rising from the ground from the point that directly lines up with the pool system. The amount of water in my opinion was significant. Is this normal or a broken pipe and if normal why bother to have a waste connection spot on the sand filter if it is coming out of the piping underneath the ground?
3- With a gas heater attached to this system can I assume that even if you don't turn the heater on you must always have the flow of water open to the unit in order to function correctly and more importantly to back wash and rinse properly of else the pool wont clean out its junk?
Thank you for your time!
