    Is it OK to turn waterfall all the way on? On booster pump with pool cleaner

    We just moved to a new home that has a main pump and a booster pump. In the plumbing with the booster pump, there is a two-way diverter for the pool cleaner (Polaris 280) and the waterfall (sheer descent). I had a pool guy give me an orientation and he said not to turn the waterfall all the way...

    Leak - Pool Builder Wants to Drain and Inspect Behind Liner

    I've had a leak for a few months. It's an inground vinyl pool, about 6.5 years old. The pool was losing an inch every couple days in the summer, and even in December it was losing about 1/4 inch per day (air temps in the 30s to 50s). I did do the bucket test and the bucket had zero loss for...

    Vacation for 5 days - how to project FC loss

    I recently learned the hard way that FC loss is not linear or constant. At a target FC of 5 ppm, I was losing about 2-3 ppm per day, so I thought that for a 5 day vacation, adding 3x5=15 ppm would be plenty of chlorine. But it was not enough and I got lots of algae. I read some posts and...

    How much to suction from Skimmer vs. Drains?

    My skimmer and drains are on the same valve with a hand crank. I can have water suctioned through one or the other, or partial from both. I have always kept it right in the middle -- 1/2 drains, 1/2 skimmer. I understand the importance of having at least some water coming back from the drains in...

    Should I remove chlorine feeder now that I use only bleach?

    My pool came with an automatic chlorine feeder (Hayward brand) that is plumbed between the pump and the filter -- the kind where you put chlorine pucks in and turn the dial to open or closed. I switched to BBB a couple years ago (thanks to this wonderful site!) and have not used pucks since. So...

    Is a pool cleaner necessary?

    I have a relatively small (16' x 28') in-ground vinyl pool. I used to have a pressure side pool cleaner with an attached bag for debris, but it would always get stuck at the same spot by the stairs, no matter what adjustments I made. So I removed it over a year ago and now I just use a leaf rake...

    Refilling a Vinyl Liner after 60% Drain

    I have an in-ground vinyl liner pool, about 4 years old in good condition. My CYA was about 150 (from prior puck use, now I'm on BBB), so I just drained about 60% of the pool, making sure to keep at least 1 foot of water in the shallow end. I'm refilling right now, and the sides of the liner...

    Is high CYA a problem if pool looks clean and clear

    I have an inground 12,700 gallon vinyl-liner pool near Sacramento, California. For the past couple years I have used pucks and bags of shock, and this summer I developed a bad algae problem that took about 2 weeks to clear up with constant brushing, vacuuming, backwashing, running the filter and...
