is it the heater tap leaking? or is a hose that is leaking going to the heater tap? i had a leaking hose but got recommended to replace the heater tap as well as 9 times out of 10 it will break due to it is very brittle.. I managed to replace the hose without breaking it and it hasn't leaked ever since, $215 is way over priced your better off doing it yourself its not hard at all
