I am getting concerned that I have a liner leak. First, the weather here has been hot, dry and windy for the last month with cold fronts passing through bringing in dry air, which never happens in August. Through all of that my water loss has grown to about 1/2" a day. The heat has backed off...

We are changing the liner in our pool within the next few weeks and I need to know the best way to handle chlorination during the refill period. The pool is around 25,000 gallons and it should take about 40-50 hours to fill with the hose based on the top off I gave it after the winter. The tap...

Is this hose okay for a temporary hookup on the outlet side of a pump? A few days at most. I want to test my new pump (Pentair #304204 Dynamo 1 hp 2 speed) without waiting to set up the PVC connections. I've got about 15 psi on the existing 1.5 hp Dynamo, but cant find a pressure rating for...

I discovered that my liner is leaking. It's under the skimmer and the previous owner had laid out a path of flat cinder blocks leading up to the skimmer area and hidden the leak. There is a patch on the liner where it is leaking and several other patches in other areas of the pool. It's...

My 1.5 hp Dynamo pump is leaking where the pot mounts to the pump housing when the pump is off. The picture below shows where it is leaking. What holds the pot into the pump housing? The pot looks like it is sagging a little. Is there a way to tighten it from inside the pump housing. I have...

I bought a bottle of Aqua Chem Algae Eliminator before I found the TFP web site. The active ingredient is dimethyl benzyl ammonium chloride. Should I keep this stuff or go ahead and take it back? Thanks, Russ

We've had the pool open for about two weeks and have had a continual brown dust problem gathering in the bottom of the pool. Test results are: FC=7 ppm CC= 0 pH = 7.6 CYA = 40 Alkalinity = 90 CH = 170 I've read a lot of the old posts with this problem and it seems to fit the same pattern as...

Here's a question I have from my one pool store visit last fall. They told me that I should only rotate the selector handle on the Sand Dollar multiport valve in one direction (I forget which) or it would tear up the spider gasket in the valve. Specifically this is a Pentair #262506 valve. I...

We bought a house with a pool last fall and we are getting the pool opened up now for this season. The pump is a Pentair Dynamo 1.5 hp with 110V service run to the pool. The filter is a Pentair SD60. Both filter and pump are probably 8 years old. I put a clamp ammeter on the motor yesterday...

We bought a house last fall which already had an above ground pool. The skimmer has no name or model number anywhere on it, but I found an instruction sheet for it with other information left by the previous owners. The company name is Competition and from looking on the internet, I gather...
