Hi All, Does anyone have experience on tightening this union for a System 3 filter? I can’t get it to budge in any direction. Also can’t get a strap wrench in it.

Hi guys, My pool has persistent iron staining. Two seasons ago I drained and acid washed. Last season I did an AA treatment and then drained. Pool was clean all summer and closed clean. I just opened the pool and found iron stains (confirmed by absorbing acid test) again. The iron stains are...

I am in the process of opening up my pool and noticed the floor of the heater is really rusted. The rest of it seems to be in fine condition. Is it safe to operate. Can I replace just the floor?

Last season I had a continuous drip coming from the union. Unsure if it was the black union directly attached to the filter or the white union on the adjoining pipe. I tightened the pipe side as much as I can but can’t get in to tighten the union in the filter; not enough space. Any advice would...

Can’t seem to find a replacement fixture for my American Products light fixture P/N 98708400. My current one somehow burned a hole through the casing and I need to replace it. Anyone have a current part number that would work? Thanks!

Changed all pool light bulbs to LED this year including Spa. Also switched to SWCG. A couple months later the spa light stops working. I just got around to dealing with it and found this hole in the housing. The housing is original to the pool I would guess (1997). Any chance the bulb or SWCG...

I’ve been seeking and using the advice on this forum for a long time now but never had the opportunity to give back. So hopefully this post will help someone! I finally bit the bullet and bought a robotic pool vacuum— a Maytronics Dolphin Aquarius XL. My plan was to leave it in the pool while...

I’ve got some stubborn staining in a pool that I inherited when I bought my home two years ago. The house was a foreclosure and the pool wasn’t being properly maintained for sometime although the bank did open it and install new pumps and cover. Last summer (second season with the pool) I...

I have a pool with significant staining. I’m currently doing an absorbic acid treatment and some stains are reducing but others won’t budget. I’m planning to drain the pool after the AA treatment. Can I acid wash some of the residual stains while the pool is draining? If so do I need to raise...

Hello! A couple of years ago I purchased a home with a pool that had significant staining. Last year I had the pool drained and acid washed; staining was greatly reduced but there’s still some residual. I’d like to do an absorbing acid treatment and then drain the pool again (I don’t want to...

Hey all, I have an old Compool controller that controls my pool equipment including lights. An issue I’m having is that my lights don’t turn on when I’d expect them to. I push the button but lights won’t turn on. Hours or days later they will turn on. I hear the relay in the CP-2000 unit at the...

Hi everyone! I recently purchased a home with an inground pool. When viewing the home last summer before purchase I noticed staining in the pool. I opened the pool last and same staining exists. It does not brush off. Was hoping that slamming the pool would lighten it but no such luck. I’d...

Hi! I recently moved from a home with a pool that I maintained myself using the amazing advice and methods on this forum. My new home also has a pool that I intend to maintain myself. Directly next to the equipment pad there is a pit that is made of cinder blocks. This pit has a wooden access...

Hi everyone! I am installing an auto fill on my pool by tapping into my irrigation supply line. The irrigation system currently doesn’t not have a backflow preventer but I believe I need to install one for the auto fill. I am not quite sure where to install it (e.g. basement, outside on main...

Hi Everyone, This is a bit of a long story but hopefully the information will be helpful in troubleshooting my problem. I inherited a 22,000 gallon Hallmark Hybrid pool when I purchased my home two years ago. It is kidney shaped, the walls are fiberglass, and the bottom is concrete with...
