Hello all,
I recently purchased a home with an in-ground pool (I have never owned a pool before). The existing pump was bad, inner seal leaking water into the pump rusting it from the inside out, so it was making a horrendous noise. I am using the existing filter which is a 100 sq ft filter in a very old Pentair tank (probably 15 years old), and the pool is about 10,000 gallons. There is a newer salt water system attached as well. I believe the salt water system is designed for an above ground pool, but this one seems to be plumbed in nicely.
Anyway, when I replaced the pump (1 hp Harris in-ground pump 240v) I decided to replace most of the plumbing and also add in a dedicated vacuum line which was already existing in the pool but never hooked up to the pump (not sure why). If you look at the pictures you'll see there are 1.5 inch suction lines feeding into the diverter, then to a 2 inch line feeding into the new pump. Then a 2 inch line out of the pump and reduced to a 1.5 inch line going into the filter, and 1.5 inch line the rest of the way out. In the pool I have three return lines all 1.5 inch. All of the plumbing you see in the picture is what I pieced together. Before I took it all apart the 2 inch out line was reduced after the salt system.
The problem I have now is the pump basket only fills about half way with water and a lot of bubbles come out of the return lines. At first I was thinking air leak, but now I'm wondering if reducing the 2 inch pump output to a 1.5 inch line creates back pressure and doesn't allow the pump to operate properly? I am thinking the line is incorrect because I was messing around with it the other night after the pump turned off and I accidentally left the air relief valve open on the filter. So when the pool turned on in the morning it was spraying water out for about 30 minutes before I realized it was open. After turning it off I saw the pump basket was just about completely full of water and only a few tiny bubbles were seen in the window. I figured the extra pressure relief was enough for the pump to work properly? Also, my filter pressure is constantly at 15 psi, is this too high?
So, do I need to re-do the plumbing and move that 2 inch reduced to 1.5 inch to the end where it goes into the ground?
Thanks for your help!
