The wife and i have our first home with pool since 2016. I never imagined of how much there is to take care of pool and the equipment running it. Always something breaking, always fixing things. But, its worth the efforts. And it kept us from going crazy during the lock down by giving us some entertainment. I am hoping to find some advice with the maintenance and repair of, and in exchange to help others with my experience i have had so far. And I had a lot of problems. The pool is 20 years old, 16,000 gallons, pebble tech, salt water, aqua rite T15. I have Solar water heater , most of equipment is Hayward, but main pump is now Pentair VS. It uses half of the electricity the old Northstar one speed pump was using. Water slide and spa still run the old Northstar pumps.
