Hot water expansion tank absorbs the expanded drinking (domestic) hot water produced by the water heater and prevents excessive stress on internal plumbing system components and frequent discharge of the pressure relief valve.
We offer a wide range of hot water heater expansion tanks - from small residential (system mount) to large floor standing commercial models.
Both Amtrol (diaphragm type) and Calefactio (bladder type) are great quality tanks, which come factory pre-charged and are NSF certified for potable water applications.
We also stock an extensive selection of Well-X-Trol well water expansion tanks.
This product does not meet the new low-lead criteria defined in Safe Drinking Water Act
and cannot be used for potable water applications,
including for drinking and cooking. This product can be used for non-potable water
Why don't we show the price?
While PexUniverse.com reserves the legal right set its own product pricing, some
manufacturers require internet retailers to display a price at or above
manufacturer's established MAP ("Minimum Advertised Price").
Since our price for this product is lower then MAP, the manufacturer does not allow
us to display our lowest price until you place the product in the shopping cart.
This allows us to continue offering our lowest prices while staying consistent with
product manufacturer's policy.
This process does not require you to purchase the product - it can be easily
removed from shopping cart if needed.
We understand that this is an inconvenience and are continually working with
manufacturers to educate them on how MAP affects our customers.
