Hi jagans & joecaption
Thanks for getting back to me,
This was a Trial and error for me, worked out in the end.
Yes, I was careful to just blow thru the Hot water feed without having the Cartridge installed and my Gas Hot water heater was installed in 1991, not too bad for that HO Smith unit, but is that where the "scale crap" is coming from ?
2 Questions I have is the thought of stopping the Junk from getting out into my Copper delivery system, I could put a Sediment filter on the "Out side" of the water heater. and a Whole house system, I have been looking as my Wife would like that - what system is out there that's not $500.00, I'd blow out the Faucet if I had to every few years, it's not a problem, my wife likes it when I fix this stuff
Makes her feel she is Lucky !
