Re: heater valves

Huw,

There are different constructions to these things. I think the ones with the
multi sized holes are the older ones. I don't remember how the newer one is
constructed (bought new & installed) but it was very different and more
functional IMO. Was pretty cheap too (appx $20). Worth checking out if your
heat is not measuring up - eh? If all else fails there is always
powdercoating. What do you think would be the best color???
