When I opened the pool the other day I found that I have two tears in my liner. The're both above the water line where the liner is white. I'm having a heck of a time finding plain white liner material to patch. I called all the local pool shops, looked on ebay, and have been searching with...

How can we remove these dilapidated stickers from our inground pool without harming the fiberglass rim? It seems like what remains of the stickers is sun baked into the fiberglass. We've tried Goo Gone, 409, etc to no luck.

I have a half-union 2" PVC ball valve that's missing its o-ring. I think the valve was made by Hayward. The logo on it is an "H" with waves through the middle. What's the best way to find a replacement o-ring? Are these things standard? Can I walk into a pool shop and tell them I need a...

I have an AO Smith S48B74A03 motor that I'd like to fix. Here's the story on the motor. It was running fine on the pool but the impeller seal was bad causing a severe leak. I tore everything down and did my best to remove the old impeller from the shaft. Nothing worked. Since the motor...

What's the consensus about using teflon tape on union threads. I know that it's the union o-ring that seals and not the threads but I've heard it said that the decreased friction on the threads allows the union to be tightened better which compresses the o-ring better which makes for a better...

I have a small 1970's vintage Fox inground pool. The pipe that goes from skimmer to the pump pad and from eyeball to the pump pad is black plastic with an outer diameter of approximately 1.84 to 1.87 inches. I know from recent landscaping excavations that this pipe does run all the way from...

My new Pentair Dynamo arrived yesterday. According to the drawing below from Pentair's website the output should be a 1.5" female NPT. There are female NPT threads on the output port but there are male threads around the outside of the port as well. There's no indication of them on the...

The pump on our little 12,000 gallon IG died and I'm trying to choose an appropriate replacement. Since the pump is totaled I can't take pressure/vacuum measurements to calculate dynamic head. I'm stuck trying to ballpark it from calculations. I'm hoping some of the more knowledgeable folks...

I upgraded to a Taylor K-2006 this season. I 've used walmart kits and strips in previous years. I ran though my first round of testing with the K-2006 today and I have a few questions. Here's the FAS-DPD procedure given in my kit: 1 - Add two spoons of R-0870 (DPD- Powder) to a sample and...
