I just moved into this house and replaced the broken old pump with a new pentair variable speed. So this will be my first time reading the pressure gauge. All the pipes are 2". I cleaned the DE filters thoroughly by taking them out. . At 2000 rpm, the psi is at 1-2psi only! The skimmer is doing a great job so i highly doubt the suction lines are blocked. I dont have a check valve either. Even if i switch to the drain, its still at 1-2psi. I even changed the gauge to make sure thats correct and made sure nothing was blocking the path way to the gauge. I have 4 return jets (3 in the pool, 1 in the spa) and if i switch the valve to the spa, i have 4 return jets in the spa.. IS it possible that this system is very efficient?? If i lower the rpm of the pump, its pretty much at 0-1psi. If i make it at 3000rpm, i can get it up to 7psi.. Is there any harm in having a low pressure system?
At my previous house after I clean the filter, the pressure would be around 12-13psi which is normal.
