    Pool heat pump - annual service needed? Unit leaked pool water and now rusted out

    Hi all, I have an Evo-heat heat pump located in Australia. I have had it just on three years and now the unit has totally failed. It's a expensive 27kW 3 phase unit. The techs said the unit failed because; 1 - the coupling to the water pipes was not properly installed so pool water ended up...

    Salt in AGP to help dry skin - will my AGP corrode?

    We are just starting to use our brand new above ground pool and we’ve noticed that our skin is extremely dry. I’ve read multiple posts that adding a little salt up to 1000 ppm can help with the dry skin but my pool is not rated for salt water. The problem is so bad that I’m thinking about...

    More corrosion questions from a skeptical SWG wannabe convert

    Hi all, After adding solar and keeping our pool warmer this summer, I'm more seriously considering adding a SWG as the chlorine demand is getting more intense. The general opinion here at TFP seems to be in favor of SWGs, and that the risk of corrosion is low. Many seemingly informed sites...
