My newly installed (Lowe's) gas, 50 gal water heater (whirlpool) is leaking water out the over flow pipe. I guess leaking isn't the correct term, it seems to be working, but why is it over flowing. My previous water heater (same house) never did this, also a 50gal, gas. Lowe's has sent 2 people over and each has come up with a different reason, but I am still not buying it. One said the house pressure regulator value needs to be replaced. (Then why did it not do this on the original water heater). The second guy Lowe's sent said we needed an expansion tank installed. (Again, why didn't I need one with the original water heater?). I am wonder if the new water heater is faulty and if I am getting the run around from Lowe's.
Thanks
