Went on a call to figure out some error codes on a pair of Rheem tankless water heaters.

All I could say was :eek:!!!

Here's the short list:

The two units were connected in series rather than parallel the same way two tank wh are often done.

There was no communication cable between the two not that it would have mattered anyway with them piped the way they were.

2 lb. gas system with two 1/2" regulators and 1/2" flexes supplying the units.

No isolation valves serving either the regulators or the units themselves.

One of the unit's vent (horizontal) was not long enough to connect properly which left about a 1/4" gap for combustion gasses to escape into the space.

No means of electrical disconnect for either unit.

The units discharged into a fully energized 120 gallon electric water heater about 15' down the line which was being utilized, apparently, as a return tank for a recirc system.

Well all I can say now is that it will cost plenty to go back and correct it all.

This is the worst install I have ever seen.

I'd love to be able to post pics but I'm on a Mac and haven't found any software that will let me get the file sizes small enough to post.

:laughing: I love those Joe Home owner jobs.
I come across a lot of mega home owner hack work. Would love to take pics with my camera phone but my brand new cell phone camera has no flash. My old one took nice pictures.
