Hi there,
My first expansion tank with the Navien tankless water-heating system was leaking in about 2 years so I replaced it with a new Calefactio HGT-30-4.8 us gal tank 9 months ago. However, I just found out today, it is leaking again, not event last 1 year?!!!! I have no idea that is the problem of Navien water-heating system or just the low quality of the tanks?
I know I have to replace the tank, again, but just want to get some opinion if my Navien failed me again!!!
Thanks for reading!!!
