NE SD | I had a similar issue with 2 of mine, took the valves apart and saw they had alot of condensation build-up and and that things were pretty rusty on the inside, but i do believe on the 4410 and later they used different valves, i guess its just a thought maybe you could take the cover off of one and see what it looks like on the inside!!!!!!!!! BTW, replaced all of mine with Banjo and haven't had a issue since!!!!!!!!!!!!!!!! | |
