Okay so now I'm neck-deep in research mode. This all started because I was trying to find what bearings I need without tearing the pump apart. Alas, I can't seem to find anything. Perhaps my Google-fu is weak.
So now I have additional questions.
1.
Pump size vs filter size. Is there a general rule of thumb about this? My pump is a 1.5hp single speed (will update sig momentarily with model #). Filter is as noted in sig currently.
2.
Plumbing. I actually don't know the size of my pipes; I'm about to go out and look. As far as pressure and head and all that is concerned, I need to know not only the diameter of the pipes but how far they travel, correct? Of course since everything is underground I won't have an exact measurement; is an estimate close enough?
3.
Eyeball returns. My husband bought a couple of these and fitted them into the existing returns; our filter psi rose to 29 and he thought we were losing water (I didn't notice anything but I'm also not super observant). Haven't done any tests yet but we took the eyeballs out anyway. Filter now running somewhere between 22-25, I believe. We had to buy a new pressure gauge and so I don't actually know what the pressure was before I fixed the filter (replaced lateral assembly and replaced 1/2 of the sand). Could the increased pressure have caused a leak somewhere?
4.
Pressure gauge. I haven't checked in a couple days but the last I saw, even when the pump was off, the needle was around 10. Remember: brand new gauge. Is it broken already? Does it indicate something else is wrong?
5. AM I WORRYING TOO MUCH AND SHOULD I JUST REPLACE THE G-D BEARINGS???
I tried to do my own research but I was drowning in hydraulics (hyuk hyuk).
Thanks!
