Test #1 today for my hillbilly pool heater...
I used a submersible pump with a T to divert some of the water..... so it would feed slower...
worked pretty dang good....
BUT...
it's still got a slight rust color coming out....
it was REAL bad when I first fired it.... let it run in the grass till it cleared out.. so I thought..
but I can still see it clouding the water orange/brown slightly when it hits...
Any idea what I can fill the upper (coil) chamber with to rid the rust?
I have some Phosphoric acid I may try.... I have a feeling most of the rust is on the bottom of the coil/chamber anyway...
Ive used that successfully for rusted gas tanks...
all thoughts welcome...
water is scalding hot coming out .......
