Title: Thermal Expansion Tank Replacement
Post by: DUNBAR PLUMBING on December 31, 2009, 09:20:33 PM
Dunbar Plumbing replaced a leaking thermal expansion tank off of Ridgepoint drive, in the lakefield subdivision, independence kentucky.

Had a pinhole in the tank, even though the bladder was still functioning.


CPVC was used for the potable water supply and they tried without success to break the connection loose from the brass to cpvc connection.

It proved difficult but we managed to get the defective tank removed and install the customer supplied tank. Also changed the thermostat

settings on the electric water heater. Setting was 150 degrees, lowered it to 120 degrees < Kentucky State Code.


Customer thanked us for our quick response.

Here's a video we put on youtube showing what a defective thermal expansion tank has inside of it.

Hey I found a thermal exspansion tank installed horizontal in the attic of a multi million $ home yesterday with no support. Along with a freaking mess of a pex install. I will take pics but it will be a week or two. Its a sight to see.
