Anderson Brass just sent me a new 4-way valve. My current problem is that I've taken the various connections on/off too many times - the washers are not keeping a tight seal. I'm looking for replacement PVC hoses (3 of them are about 12 inches, another one about 3 feet - although at least a couple of them have 90 degree fittings on one end). I've looked online, but can't find any. Does anybody know where to look?
