Hey y'all - I'd like to piggyback on this thread. I've also got a Watkins 240V6KW heater and think I have the same leak as Sea4me. Haven't removed it yet to see if I can pinpoint the crack/leak, but am hoping I can use some type of sealant or find a repair kit. Any advice welcome...rather not shell out $400+ for a new heater, if possible. @Sea4me - where did you find the replacement endcaps for $120?
TIA
Mike
