I hear most people need to constantly add acid to their pools as the pH rises. The pH of my pool always goes down. I have never added acid and am constantly adding washing soda. Typical test results: FC: 3 to 6 ppm depending on the time of day CC: 0 ppm TA: 80 ppm CYA: 40 ppm pH: 7.4 I'll...

The plastic flange on the return of my pool cracked and about 1/4 of it fell off. The pool does not seem to be leaking now. How hard is to replace the flange without the liner moving? Am I better off replacing the flange or just leaving it? What's the best way to replace it? Thanks!

I bought a house with a liner pool in 2007. The sellers gave me a receipt showing the liner was replaced a few months before we purchased the house. When we opened the pool the following spring, there was a divot on the ledge of the deep end. The divot is about 6" x 3" and about 2" deep. I have...

My pool has no main drain. This makes pumping out the pool to lower the water for the winter a problem. I tried using a vacuum head connected to the skimmer, but there was enough air leak around the hose in the skimmer that the pump started sucking air when the water level dropped below the...

I've been looking for a description on how multiport valves work and can only find general overviews. The question of Waste vs Rinse has been bothering me. Can any of the knowledgeable and esteemed members of this board educate me? When in the "Waste" setting on a multiport valve water flows...

I just started opening the pool for the season. Everything was working fine when I closed in the fall. The equipment is fairly well protected in a small pump house, so I leave the pump out over the winter. All the equipment was installed well before I bought the house. I believe everything is...

Over the winter I had a GFI added to my pool electrical system. (The pool was built in 1967 and had none.) Now that I have a GFI, I'm finding it trips whenever there is a heavy rain. Not good. The only place electricity comes near the pool is the pump. I don't have lights, SWG, or heater. As...

Someone I know is filling in their pool and offered me a fairly new Hayward SP2610X15 pump. This is twice the size of my current pump (see signature). I estimate my current pump is 12 to 15 years old and the price of this new one is unbeatable. The filter they have is damaged, so I can't use the...

My multiport valve (probably as Pentair SM10-2D.E., but the label has long since fell off) is leaking to waste a bit. Reading on the forums I saw that replacing the spider gasket is fairly simple. I removed the six bolts holding the valve together without too much trouble. Getting the halves...

I'm now attempting to bring my CYA up to 40 ppm after it dropped to zero (see http://www.troublefreepool.com/cya-from-60-to-0-ppm-t8686.html). I know the CYA test is difficult and somewhat subjective. After carefully reading the test instructions, I'm still finding the test is very...

When I opened my pool this spring, the CYA was 60 ppm. I checked the level again a few weeks ago and, as expected, it was still 60 ppm. I went away on travel and vacation from July 14 to 21. When I was away, I set up a Hayward chlorinator with four pucks and had a neighbor monitor the water...

18 months ago I bought a house with an in-ground vinyl pool built in 1967. The liner was replaced in 2006 -- I imagine this is the fifth or sixth liner in this pool. The filter and pump seem to be about 10 years old. It looks like all the plumbing was replaced at the same time the new pump and...

I'm slowly cleaning up the deck around the pool in the house I moved into just over a year ago. There were some rather strange things done with house when we bought it. The strangest is how they built a pump house for the pool equipment. You can see some photos at...

I moved into a house with a pool just a year ago. This was the first time I owned a pool. Because I was clueless, I hired a pool company to open the pool last spring. It was the same company the previous owners used to close the pool in the fall. It cost about $450 to open the pool which...

This is my first year with a pool, which came with the house. The pool is about 12000 gal, in-ground, vinyl, with a 3/4 hp pump and DE filter. Figuring that DE came from the gound, I've been allowing the backwash water to flow onto the lawn. This leaves some DE on the surface, but it seems to be...

This was my first season with a pool and my first closing. The pool came with the house -- it's about 11 x 24, in-ground, vinyl with a 24 sq. ft. DE filter and a 3/4 hp pump. I calculated the volume to be about 12,500 gal. When I started the pool in the spring, I had trouble getting the filter...
