The thermostatic modulation gas control valve on my old AO Smith boiler is leaking gas in 2 locations. Rather that attempt a repair, I'd like to replace it. Problem is Honeywell stopped production of the V55155 line in 2000. There are a few 1110's on Ebay for $160 but non-returnable with no warranty. My boiler contractor will install one he has for $320 part + labor warranted. Does anyone know if there is a functional equivalent replacement available new?
