    Old House - Backflow Valve Question

    My house was built in 1985. There is a back flow valve but if I close it off, it doesn't appear to shut off the autofill lines. Should I care? I am trying to sort out the plumbing. We have a very minor leak and the autofill Iines were pressure tested and didn't find anything. Now I just want...

    Does time of day matter in running pump?

    Hello from AZ. In winter my electrical provider provides a big discount from 10am-3pm so I programed my variable pump to run at high during those times. Now that it's back to summer rates, I was wondering if the heat of the day put an extra strain on these motors and I should reprogram it back...

    What would your approach be??

    I am trying to migrate to using only Liquid Chlorine. I recently did a partial drain of my 25,500 gallon pool in Scottsdale AZ. Its 97 today. Pool is open all year. Full sun many days. Due to where I am on the city water line, I fight high PH all the time. Here is where I am at? FC 3 CYA...

    Waterline Scale Removal

    I read the additional reading post Waterline Scale Removal and it seems that you have to hire an expert. The Biodex and Pumice both have issues. Just checking to see if that is still the case and there are no other options to remove it?

    Bleach at WalMart - Too many choices - is this ok?

    I am trying to find a supplier of bleach that is close enough to me that it's convenient enough that the bleach can be stored in my hot AZ summers. There are no HASA dealers close enough. I found this Clorox 7.5% at WalMart and am wondering if its ok for the pool. Appears unscented. Two...

    Wall Whale - brush choices and replacements

    So I read some old threads here and have emailed Pebble Tec but no response yet so thought I would post here too. They clearly recommend nylon to start but my pool is older. Has anyone here actually used a hybrid brush (nylon and SS) and found no damage to Pebble Tec? Secondly, my nylon...

    Partial Drain; what is the risk?

    I am going to partially drain my pool. CYA is at 113. Its 27,000 gallons. My question is do I close all the valves on the pumps and filters? Turn the pump off, yes of course. What other gotcha's are there as I haven't done this before. My mistake as a new pool owner was leaving my tabs in...
