Rebuilding heads seems to be a popular activity at this time of year; I replaced all valves in my Headmate head last weekend. It's not a bad job, but I always remember why I bought the stubby Phillips #2 screwdriver when I do it. The previous weekend I dumped four gallons of vinegar into the system to clear scale off. It worked for the joker valve, but I was still having issues with the pump losing prime and not drying easily without holding the valve leaver down. Once apart, it was pretty obvious why - the metal backing washer from one of the inlet valve had corroded off the rubber piece, and while I was there I just changed all the parts that were in the service kit.
Joker valves seem to be common across head designs, and a necessary evil, but I am fed up with having to rebuild the pump on the Headmate once or twice a year, so am planning to replace it this winter. Can anyone share experiences with their heads (ours gets very light use, strictly no solids)? I am considering the Jabsco Twist n Lock or the Raritan PHC.
