I have a salt water pool and a new Rheem P-M206a. The manual recommends:
Salt - 4500ppm Max
Total Dissolved Solids - 3000ppm Max **
Underneath the table the ** is explained as:
**In salt water chlorinated pools, the total TDS can be high a 6000ppm.
Does this mean 6000ppm is the TDS max for a salt water pool or is it a warning for swg pool owners and 3000 is still the max? The second option doesn't make sense to me since 3000 is a normal salt level and they even state 4500 max for salt.
The manual advises:
"If the mineral content and dissolved solids in the water become too high, scale forms inside the heat exchanger tubes, reducing heater efficiency and damaging the heater."
I had my chemistry tested at the store the other day and TDS was 4000ppm, outside their range of 300-3000ppm.
My salt was 2700ppm. What does this mean? Does my reading mean 4000 total = 2700 salt + 1300 other things (my guess)? Or 2700 salt + 4000 other = 6700? I would guess that my TDS & salt is within Rheem requirements ie less than 6000 and less than 4500.
I've read on here not to worry about TDS. I checked a Pentair and a Hayward manual and they don't mention TDS. What's the real story?
In addition to water chemistry, the manual recommends periodically checking flame (easy visual inspection), checking the voltage on the water pressure switch, cleaning burners, and tube cleaning. Anyone do these themselves or best to have it done annually by a serviceman?
I dismantled the old corroded Raypack 2100 millivolt heater so I can bring it to the junk yard and learned alot in the process about how they are built. It seems pretty much to be the same design except for the digital control and electronic ignition. Are there any parts worth salvaging?
