converting to a salt water system with a heater/metal parts

[thetinkerer]

I am considering converting my fresh water pool to a salt water pool...One thing I am concerned about is corrosion of metal parts...I have a heater that heats the water in our jacuzzi as well as the pool.....

A check valve installed on the inlet line to the heater is supposed to prevent salt from entering the heater..

If I did not have a heater I would not be concerned but having a heater well what do you think...?????????

Advice? TIA

The low concentration of salt will not affect your heater. There are MANY that have heaters with SWG's with no issue, including myself. My water goes through the heater full-time.

I'm a little confused, if the pool water runs through the heater it will always have salt in it, and conversely if you have a check valve before the heater nothing would work.

It's sometimes advisable to have a check valve between the heater and SWCG (which should always be installed after the heater), to prevent heavily chlorinated water from backing into the heater when the pump is off.

Sounds like you are right about the location of the check valve...thanks!
