Thermal
Expansion
Determine if a check valve is present on the inlet
water line. Check with your local water utility. A
check valve located in cold water inlet line will
create a “closed water system”. As water is
heated, it creates an increase in pressure within
the water system because the increased volume
of water doesn’t have a place to go.
Referred to as “thermal expansion”, the rapid
pressure increase can quickly reach the safety
setting of the relief valve. This will cause the
relief valve to open during each heating cycle.
We recommend installing an expansion tank to
control thermal expansion.
Connect the thermal expansion tank to the cold
water supply line (see Installation Instructions).
For additional information, contact installing
contractor, plumbing inspector, or water supplier.
