I understand that completely draining a pool is abnormal and not normally recommended. This pool however is 50ft wide x 50ft long with a depth of 1-3 feet. In order to winterize the pool with water in it more than half of the water needs to be drained anyway, about 23,000 - 25,000 of about...

Nevermind, I figured it out. I've been deep cleaning for over an hour now with 4 hoses. There's still junk coming out. This filter hasn't been cleaned for 15 years, possibly for over 50 years.

I tried to deep clean one of the filters today. Unfortunately I couldn't overflow the filter. The water just ran right through the multiport valve, which was on "closed," and backwards into the filter basket as well as out the waste line, and into the returns. I replaced the spider gasket a...

Got it. I'll take a look once I finally get those awful caps off tomorrow. Is there any way to make sure it will be easier to remove them next time? When I opened the one up last year I made sure to use plenty of lube, and it is definitely on correctly, but it's still jammed real tight. And...

How can I tell if I need to remove it? Low flow rate? Is there any way to tell by looking at the sand if it needs to be changed? And Tim, Deep Cleaning involves opening up the cap and sticking a hose in the filter and overflowing it, yes? I'm asking because this filter is inside. It's not...

Last summer I had to replace the pressure gauge/release valve on a Pentair 100c filter. When we opened up the cap (which was a 6 hour awful task) the inside of the filter smelled horrible, and I could see the inside of the filter was a pretty big mess. This is a free community children's pool...

Thanks for the ideas on places to look. And don't worry Patrick, I already know what to do, and already did it. I just was trying to remember where the law is because the current project I'm working on at these pools is "Stop breaking laws." It's a project that got held up with old...

It's not commercial or residential. Borough pools run by the local government. So for the most part, same regulations as commercial/public pools.

So, I need a little help from somebody with a better memory than me. I know it is illegal to have a chemical storage area that is separated by a permeable barrier (like an indoor fence/gate). You need a solid barrier or the rest of the area is considered chemical storage as well. I know this...

Thanks, the owners are the town government. These are free community pools, (not that uncommon in NJ). I'll take some pictures in the morning and post them when I can.

I'm a pool manager in NJ who is taking over some pools with problems. Both pools have Hayward sand filters. The sand for both pools hasn't been changed in 6+ years. There may also be broken laterals. Pool A I found that Pool A's filter reeks inside after opening it up and I can even see...
