I need to replace the front housing of pump. It cracked and spews water when the pump runs. I found 3 different part numbers for the front housing, and don’t know which one is the right one. How do I know which part I need? Also, when I replace the grey ABS outlet pipe, what is the best way...

I left for work in the morning, and when I came home in the evening, noticed that the water level was down several inches. The pump runs from 12pm-5pm daily, and I know that the pool was full when I left in the morning. The pool water level was just below the skimmers when I returned. The...

I have a Century Electric B855 2hp motor running my Pentair pump. After a big storm 2 weeks ago, I found that the motor wasn't running. It hums and trips the breaker. I figured the capacitor may have died, but the capacitor looks fine - not bulging at the bottom as it has in the past when...

Hello all. My setup: 18K chlorine inground pool, Pentair DE filter, main pump has 2HP motor, Polaris cleaner with 3/4HP motor, waterfall feature with 3/4HP motor, and 2 nonLED lights. The switches for the waterfall and lights are located in a separate location far apart from the filter...

Hello all. About 10 days ago, I noticed that my pump wasn't running. The breaker was tripped, and when I reset it, the motor hummed and then tripped the breaker again. I looked around on the internet (including here) and figured the capacitor was bad. I was able to turn the shaft by hand...

Howdy all. Firstly, thank you for all the helpful information you provide. I have learned alot on this forum from trying to troubleshoot a few problems since I have joined. To the matter at hand - My pump is leaking at the outlet where the vertical grey pipe threads into it (red arrow). I have...

Recent convert to the BBB method. Testing with TF-100, and my numbers are in line with the recommended values for CC, CYA, pH, TA. 18000 gallon, in ground, gunnite pool. Was using trichlor until I noticed brown stains and found my CYA= 100+. Current values: FC= 1 CC= 0-0.5 pH= 7.2 (lowered with...

Recent convert to the BBB method. Returned all my trichlor and cal-hypo "shock" (I know - its a verb, not a noun) to Costco and spent the day testing the pool after the second partial drain and fill to correct high CYA and CH. One question though - while at Costco I noticed they are selling...

My pool lights are the 8" Pentair type. The bulbs (500W) had gone out in both, so I recently replaced the bulbs when I was draining the pool partially. When the bulbs had fused, they did not just go off immediately as I have seen other incandescent bulbs do... the brightness sort of faded over a...

Hello all. New member. Apologies if this should go to another section - the description suggested this was the area for discussing stains. My pool: 20K gallons, plaster/gunnite, DE filter, trichlor. My numbers from testing at Leslie's: FC 5 CH 480 CYA 120 TA 60 pH 7.2 I know that Leslie's...
