Hoping you guys can help me.
For 2 years (1 summer) we have been limping along with this pool, we even hired someone to take care of it, but he gave up and disappeared.
The pool is an outdoor, gunite pool, built in 1990. It is 75 ft long, and the width varies from 10 ft to about 25 ft. I estimate the volume to be about 72,000 gallons.
The pump is a Pentair IntelliFlo VF, the filter is a Jandy CL-460. A Pentair chlorine feeder is plumbed in after the filter.
The cleaner is a Polaris 9300 Sport robotic.
All of the piping around the equipment is 2" PVC. There are 2 skimmers, both have 2 holes in the bottom (neither has any diverter for switching between the holes).
There are 4 returns, the returns are 1" PVC, cut off at the end of the plaster, not threaded, no eyeballs.
The equipment is placed at one corner of the pool, and the return there is very powerful, while the one in the other (shallow) end is weak.
There are air bubbles coming out of the powerful return, and air bubbles in the pump basket.
There is a 3-way diverter valve in front of the pump, switching between the 2 skimmers, I am very suspicious of this valve as the air leak, when I place my hand around the elbow attached to the valve I can hear the sucking noise change. It is an older, grey colored Jandy valve, not the never lube kind.
Current problem, pool is just not getting clean. Been running the pump on manual at 100, 110, 120 GPM for days, still have cloudy water. The filters do not look that dirty, we have 2 sets, and rinse and reload, and keep trying.
The gauge on the top of the filter is not working, it was replaced by the pool guy before he quit. So its brand new, just installed, but not working.
Also replaced all O-rings in the filter, the O-ring in the feeder, and the O-ring at the pump basket.
The filter manifold was replaced too.
The pump seems to think there is pressure, (it reads filter at 67%), and it does prime, and run, and I can see and feel water coming out of the returns.
We had been testing with bad kits and strips until we found this site and started reading. We ordered the FAS-DPD kit, and here are the readings I got (keep in mind, this was my first time using this kit).
FC: 0.6 PPM
CC: 4 PPM
Calcium carb.: 490ppm
Obviously it needs chlorine, but I am still concerned about the filtration issue.
We tried, about 5 days ago, to raise the chlorine level to over 5PPM at least and poured 8 gallons of 10% liquid chlorine in.
The test kit we had read around 5PPM at that point.
I stopped adding chemicals until the better test kit got here.
When we called the pool guy originally, the pool was green and had an algae problem (yellow algae, mustard algae?).
Now there is what looks like sand all over the pool.
When I run the Polaris it gets clogged after about 15 minutes. Should I just keep running it over and over?
The pool guy complained that he could not get his vacuum to work due to suction problem.
He was blaming it on the manifold.
How do I clean the filter cartridges well enough that they will work again?
1 sets is about 1.5 years old, the other is about 1 year old.
I was planning to order another set just to see if it made any difference.
Thanks for any help or suggestions!!
