Quick and easy.
Well the product is pretty self explanatory. It was shipped quickly, arrived on time, was packaged well and was simple to install. It replaced the old one that was there for 12+ years and the diaphragm had holed through causing the tank to fill completely with water.
The hardest part was checking and charging the air preassure ti the required 15 psi for my system. Mainly because I don't have a digital air preassure gadge.

Almost 5 Year Lifespan
I like the design with the clear schrader cap and all. But good thing it's there because you'll need it. Also have found it needs about 5psi added each year. Meh

Q: I have a Extrol #30 expansion tank. The direction say to mount this tank vertical rather then horizontal. Why is that?
Asked by Bill 16 years ago
Add your answer
Verified Reply- PexSupply StaffThis tank, like any diaphragm tank, works and lasts longer when mounted vertically. In the horizontal position, the diaphragm lays on the side of the tank. As the diaphragm goes back and forth, it rubs against the tank and could wear itself out prematurely.

Q: I'm losing about 1 gallon a day from my blow off on a hot water system.. I changed the relief valve (30 psi) but it is still blowing off. Currently the system has an Extrol Expansion tank # 30. Perhaps it went bad and needs to be replaced... Any suggestions.. Thanks.. M
Asked by Mark 16 years ago

Verified Reply- PexSupply StaffIt sounds to us like the bladder may be ripped in the tank. There is an air shatter valve on the tank--press it in and see if water comes out. If so, the tank needs to be replaced.
