Replacing Heater Ourselves?

If you have the same or near heater type, this should be an easy install.

Make sure there are Unions at the in and outbound plumbing lines of the heater. If not, then now is a good time to install them.

Next, do you have a check-valve btw the SWG and the heater? if not, then a Jandy ck-valve is something you should highly consider.

Finally, if your husband knows a reliable plumber, he could pay him to come inspect the job and certify if all specifications are met and all testing passes. This overcomes the DIY barrier of voiding warranty for a pure DIY install. If you can post a pic of your heater from the plumbing side, we can determine if you have unions and/or a ck-valve; just make sure the pic includes up to the SWG - good luck in the Garden State - tstex
We do have a local plumber we use for stuff so that’s a great idea. And to clarify do I need the ck-valve since the comment after said no? I’ll post a photo if it helps.

No, Marty was correct bc you have a SWG that doesn’t produce anymore chemicals after it’s off, unlike a CL tab dispenser that continues to produce CL as the tabs dissolve / i use Tabs only to increase CYA as required.

Per Jimmy above, there are very, very few companies that manufacture their own products. At best, they design a few module boards, then maybe assemble the main parts, but ultimately slap their name on the finished product. Therefore, look at overall reliability, support of product and warranty timeframe.

Take a pic so I can see the puping going in amd out of the heater. In your pic its taken from above get low. Then take another pic of the gas line into the unit. That's an old style Hayward surprised it was still working

That heater may still be available. Google "Hayward H250" and call some of the places you get. You might just get lucky:


That would be a trivial replacement job.

It’s not working :) When we bought the house we were told it was up to us to repair and we never felt we needed a new heater until this season so we just left it.image.jpg

Yes except for the same prices as new ones it’s probably less efficient and maybe not built as well?

The way the heater is sitting I don't think it would be that hard to replace with any model heater. You might have to make the pad area a little bigger :)
But the plumbing and gas line all look like you have room to rework.

Well he did it. We went with the Rheem Raypack and it should’ve been a fairly simple swap and rerouting of plumbing. But of course nothing is simple in our house. When he took away the old heater he found that there was actually no electric connected. At some point (and we have no idea how), the electric was just cut/never installed/ missing, who knows. So he had to tap into the source for the filter and SWG and configure all new wiring. Then when he turned on the gas it took a while and we weren’t sure there was even gas actually run (not unexpected since the electric was MIA). But in the end, a day and a half later we have a working pool heater. Thank you all so much for the help and advice.

Probably saved yourself $1000 😇
