sand/silt in pool

[uaguyua]

Thanks Ben. I didn't realize that my pump/filter were mis-sized (the manual says the acceptable flow rate is between 73gpm and 98gpm). I had assumed this was okay since the HR in HRPB30 stands for 'high rate'. I will look into buying a smaller pump.

I was kinda guessing that either I missed a problem with a lateral or the hub or I somehow damaged the laterals when I put the new sand in (I followed the instructions and filled it 1/4 way with water). But my main question for the forum is 'Do the tiny mesquite leaves blowing back into the pool indicate that something else really serious is wrong with the filter or could they also be caused by a broken hub/lateral? I don't want to spend a lot of $ fixing the lateral/sand issue only to find something else is also wrong. At this point should I just bite the bullet and buy a new filter or is there anything more I could do to diagnois this?"

thanks again,
Dan.

The "high rate" thing references some old changes in filter ideas, that were mostly bogus at the time (30+ years ago).

The leaf problem points to something like the filter air vent. If there is an air vent, it should have a screen or something like it, on the upper exposed end. A small leaf could transit that tube, under certain conditions. Look at the part #12a in the image -- that's what WOULD keep out the leaf, if it were there.

Regarding the pump, depending on the particular pump model, it may be possible to replace the impeller / diffuser so that it will run as if it were a 1.5" HP pump -- the electric motor won't care, and your electrical costs will go down, while your filter efficiency goes up.

BUT . . . before you do that, you'll need to send photos to [email protected] of the pump, filter AND piping. I'll post them, and we'll see what's possible.
