    Jandy LT - hose from air flow switch

    I replaced the fan motor on my Jandy LT heater circa 2007 with the same model circa 2013. The new model does not have the hose connector for the air flow switch. On newer models where does the hose connect? I can drill and tap a place to put in a fitting but wanted to ask first.

    Jandy JXi 400N Not Igniting - Help

    I opened my pool two weeks ago. At the time, I was able to fire up the heater and it ran for about 20 minutes before mysteriously shutting down. I decided to troubleshoot this on my own which may have been my first mistake :) I used the troubleshooting guide in the "Workbook JXi Pool & Spa...

    Internal bypass valve Hayward H250

    Hello Everyone, Just discovered this site after converting to a SWG. Had the pool installed 14 years ago and had a real good run as far as everything holding up. Only issues were a Pump motor, 3 sets of pump seals and a heater digital control membrane (all of which I was able to DIY). Got 14...

    Replacing Laars Lite 325K with Raypak 366K

    Old Rheem Gas Heater Good or Bad?

    I have an older Rheem Gas Heater (Model No. P-M337-A-EN-C) and was wondering if it's in good enough condition to use safely. I took everything apart as best I could and it appears the wires are in good condition (not chewed or ripped). I did see some Gekos in there but I believe they're gone now...

    Heater Questions from a noob

    Hey guys, I inherited a pool when I bought a house last fall, and the set up includes a Raypak Heater (Model 156). I just have a few (probably stupid) questions. 1) During my summer start up, should I try to isolate the heater from the system? My pH is likely going to be low on start-up and I...

    Which solar water heater?

    The second season I had my above ground pool, I built a diy solar water heater. I have a few dollars to spend on an upgrade, and I'd like to get a commercially produced version such as one by SunQuest since these are sure to be more efficient than mine. There are a lot of different...

    Long metal stick in heater header where I removed drain plug

    In Austin and out of fear of losing power, I pulled all the drains plugs I could, opened the diverters, and allowed the pool equipment to drain as best I could. As I finished unscrewing the drain plug in the heater header, I noticed this metal stick fall into the snow. What is it? Is it in...

    New Pentair Heater Broken - Rattling Sound, Trying to Diagnose

    Our brand new Pentair heater is broken. We're trying to figure out what could be causing it and if it's a quick fix or we'll need to make a warranty call. We are hoping it is a quick fix, since we're sharing the pool with several other families (with a google calendar so there is no overlap)...

    Hey everyone. I just replaced my MasterTemp 400's thermistor in March (old one was reading 126F so was definitely bad) and this one has been working fine all season until this week when the heater started cycling on and off within the span of a few minutes, now down to a few seconds! The temp...

    Heater Gas line size

    My previous plumber installed my sediment trap about 6 feet away from the inlet of the heater (directly out of the source line). He also installed a regulator/governor and reduced down to 1/2" pipe for a length of about 6ft to my 400k NG raypak heater (the distance from the meter to the...

    What size heater?

    I have a 24’ round pool in Michigan. We’re looking to get a heater and are between the Raypak 156 and 206. I don’t plan on running it constantly, just a few hours on the mornings I know we will swim and water is cold. Does anyone have experience with either? Obviously the 206 is a more expensive...

    Jandy LXi heater - get initial ignition, comes up to temperature, but won't re-light to maintain temp.

    Hey folks! Hoping to get some clues as to what's up with an older Jandy LXi heater that's not working consistently. Been in my house for about 5 years - pool and equipment came with the house, and was clearly a few years old at that point. Heater outdoors, but in a covered area so it's not...

    HL2 Code on Raypak r206a

    Hey guys, this season I've been getting an HL2 code on my Raypak 206a heater. I'm aware that this is because the outlet temperature is exceeding 135 degrees Fahrenheit. This happens regardless of the rpm that I set variable speed pump to. However I will note a high pitch squealing sound once the...
