Rain water as boiler water
Is rain water suitable for Independence IN-4 residential steam boiler? Rain is very low in Total Dissolved Solids, and having a PH of about 5.5, an addition of a small quantity of 8 Way Rectorseal woul bring it up to ph of 9.0.
My boiler is about 15 years old and I’ve used city water (very hard) and for the last 2 years used bottled spring water.
