Hello, I am finally going to add a SWG to my pool and am looking for advice on selecting equipment. My plan is to purchase the equipment and pay a local pool company to install it. My pool is approximately 27,000 gallons. My existing pool pump is a Pentair WhisperFlo Two Speed Pool Pump with...

My current setup includes a Pentair WhisperFlo Dual Speed WFDS-24 Pump connected to a 48 square foot DE filter through 1.5 inch PVC and a 1.5 inch multiport valve. I run the pump on low speed except for priming and it works great. I only need to run it for 12 hours on low speed in the summer...

Hi, I have a 48 square foot DE filter that is probably at least 25 years old. I think it is a Pac Fab Nautilus Stainless D.E. I do almost all pool maintenance myself - but the one thing I pay to have done is the cleaning of the DE Filter once a year. The manifold is cracked, and the grids...

So, I need to replace my multiport valve. It is a Hayward 'VARI-FLO' Model Number SP71. My DE Filter is a Nautilus 48 sq ft, it is old and I cannot read the model number. I think it is an 'FNS' style??? The reason I have to replace the valve is that a piece of male threaded PVC pipe broke...

Hi, My pool was replastered 6 days ago. I have brushed the entire surface two or three times every day. The amount of plaster dust does not seem to be reducing. While brushing, a small cloud of plaster dust can be seen around the brush. The amount of plaster dust seems to be about the same...

Hi, I'm having my pool replastered and today they did all of the prep work. They drained the pool, acid washed, and bond coated. When I got home from work tonight, my timer had turned on my pool pumps (both the filter pump and polaris pump). The pumps ran for just over an hour. Now there is...

I'm getting my pool replastered. I intended on going for plain white plaster. The company doing the work is offering to add 35 - 45% blue quartz to the plaster for strength. This would cost an additional $650. My pool is about 27,000 gallons and has 10+ year old whiter plaster that is in...

I just replaced my Polaris booster pump supply line (flexible reinforced hose. When I disconnected the old hose from the tee off if the return pipe, a fair amount of de-cloudy water flowed into the filter pump. I set the backwash valve to CLOSED to stop that and also to stop water from dripping...

My pool's main pump is dying, probably won't limp along for much longer. See here for details. I've determined my best option is to replace it. I'm trying to learn as fast as I can, there is a lot that goes into selection! I've read Hydraulics 101 and I think I understand most of it. Here...

Hi, When I turn on my pool pump, it makes a very loud vibrating / grinding noise for a few seconds and shuts off. It has been making a grinding noise at startup for as long as I've had this house/pool; over one year. It was also probably louder than normal while running after startup, but...

Two weeks ago I had my DE Filter cleaned, and everything was normal. My typical PSI after a cleaning is 6 PSI, and it has been there since the cleaning (good flow at returns as well). Last night I noticed bubbles and enemic flow from the returns. It had been 5 days or so since I checked the...

Hi, My pool FC has been dropping 10 ppm daily due to sunlight. CC is always zero and I verified an overnight chlorine loss of less than 0.5 ppm (dropped from barely 14.0 to 13.5 from 10:45 pm to 6:30 am). So I tested everything last night and this is what I got. FC 3.5 CC 0.0 pH 7.9..8.0...

When I drained the pool down, the water seemed much cloudier, cloudier than I think can be attributed to removal of the water... I left the filter running through most of the drain/refill (diverter valve set to DRAIN only - no SKIM). Right after refilling, when I brushed the walls/floor, white...

Hi, I became a pool owner in October 2009 and so far so good. Just found this website and there is some great information. So far my 'system' is based on the advise of the previous pool owner, and is working well. However, I thought I'd get some feedback on what I've been doing, as it is a...
