I have an 8 year old indirect water heater that recently developed a slow leak from the hydronic boiler inlet pipe. In my past experience I haven't seen a lot of plumbing leaks start due to loss of seal within 8 years. This might be unique due to the higher boiler water temps (180 degrees F) involved.
To avoid a $130 service 'diagnostic' call, I'd like to first inspect for myself first (retired engineer). I'm interested in removing the boiler supply inlet pipe, cleaning it up and resealing it (I'm familiar with depressurizing and filling the hydronic boiler system as I've done this several times to add treatment and rebuild all the original zone ball valves). There is some corrosion discoloring of the water leaking (brownish) from the tank fitting. Am I in for any surprises (corroded fitting that sealing won't solve) or is this really just a sealer failure (PTFE tape with/without PTFE sealer) in your experienced opinion?
Thanks!
