I need to replace my Maytronics Dolphin S200 Is Marina Pool & Spa the "go to" to purchase these? I seem to remember that units bought on the internet / non retail were not eligible for repairs under warantee? Is that still the case? Thank you in advance!

Deleloped a crack in my Leslie's Cyrstal Clear II (Hayward DE-LE-42954) 48 sq foot DE pool filter housing and after reading a number of posts relalize that replacement is the only option. Here are my questions: 1) Are the inlet and outlet tube spacing / height / location on pool filters...

So out of nowhere, the indoor / inside panel that controls my Compool cp3800 system went completely dead / dark, no indicator lights on the panel. I took the panel off the wall and disassembled, nothing obviously wrong with the circuit board, wiring etc. What are the logical steps to start...

I started noticing progressively less and less pressure in both our in ground jacuzzi as well as the pool then determined that I have a leak at a PCV joint just before the pool pump (see photo), which causes an alternating leak/suction phenomenon, so the pump never really builds up appropriate...

Minimax 250 spa heater (older model) was working fine for some time, then sporadically for a day or two, then quit completely. Upon inspections, there were no lights on the control panel, and it didn't take too much detective work to figure out what happened (see photo below). Questions: Can...

Relatively new pool owner, diagnosing an older traditional grid-style DE filter system. When I moved in, I could tell that larger items (pine needle fragments, larger specs of plant material, etc) were passing through the filter elements and returning to the pool. I read the "DE Filter Cleaning...

Thanks to significant help from fellow member on this board, I was able to get my compool 3800 / Minimax NT 250 spa working. Family is super happy and we have already enjoyed many hours of use! One small issue though... I am setting the spa temp at the control panel to the maximum (hard coded...

I am replacing the pressure switch on a pretty old Minimax 250 (IID) pool heater. The factory manual says I should buy replacement part #071580 (picture below), but this goes for over $75 online. Wondering if any of the experts can confirm that I am relatively safe to use some of the cheaper...

Adopted this nice three stage waterfall - pump, filter etc work fantastic. I'm a new homeowner and relatively new DIY'er, so my thanks and apologies to those who might be reading this for my lack of knowledge and experience. Unfortunately the lowest section, which is about 50 gallons...

Just moved into a home with an in-ground pool with a Pentair Minimax 250 NT heater that has not been used in at least five years. This unit has four LED indicator lights - Power, Pressure, Heat, and Service. With the pump turned on, the heater's power light comes on, but the unit does not fire...

Brand new pool owner here... we adopted a Hayward Pool Vac Ultra that worked well for a few weeks, but now seems to turn the same direction every few feet it travels. As a result, it seems to only clean 30% of the pool, a circular area around where the suction hose comes out of the water. I've...
