I recently self-installed a new Jandy CS150 for my 20,000 gallon in-ground pool. I have a 3/4 HP pump. Although I'm not a plumber, I understand the basics of flow, pressure, air leaks, and so on, and I think that the installation went 99% well. With the pump running, the water flow into the pool is very good.
After 2+ days of continuous filtering (in a very green pool to start with), the water is still pale greenish cloudy such that I cannot see the bottom. I've shocked and waited 18+ hours three times. When I pulled the cartridge out for cleaning, the first two times, it was full of algae and other organic matter, and I cleaned it off with a hose.
There are two anomalies that disturb me. First, the pressure has never gone above 0. I expect it to run at low pressure, but is not actually pegged to the 0 bar. There seems to be a small amount of air leak somewhere prior to the pump ingress, since after a n hour, I can bleed more air out of the filter using the top air release value. I don't think this small amount of air leakage would reduce pressure to 0, especially given the flow I feel when I put my hand in front of the wter return in the pool.
Second, when vacuuming, I witness a couple of very green algae plumes going back into the pool. This means significant water must be bypassing the filter element. I was told that there could be a rip in the paper, or missing parts that should go around the cartridge. I have two cartridges, one of which came with the new filter, and neither came with any extra parts, nor does the installation manual mention needing any, so I kind of rule that out. I'm currently using the second cartridge for the last 12 hours, and haven't yet vacuumed, so not sure if a big plume will form using it, but the water is still foggy as summer in San Francisco.
Any idea how I can troubleshoot the water bypass problem and/or the 0 pressure problem?
Thanks!
