easy to reach. Provide for clear access to the storage
tank, pump, expansion tank, mixing valve, time clock
(optional, not provided) and other key components. If
a component in the potable water side of the system
may require future service or maintenance make the
connections with brass unions. Use only brass nipples
and unions and copper and brass ttings in plumbing
the solar storage tank and expansion tank. The use
of galvanized ttings or nipples, di-electric unions,
CPVC, PVC or other plastic pipe is prohibited.
Hard copper connections to the city cold water
supply line and the home hot water feed lines
are recommended. The gaskets in standard water
heater ex hose connectors can become brittle and
compressed over time and begin leaking on the water
heater. If not detected in a timely manner even a small
drip or leak may cause serious damage to the tank’s
electrical components or, in extreme cases, may cause
the tank to leak from the outside in.
Tank plumbing is required to provide for the isolation
of the solar storage tank from the city cold water
supply line by means of an isolating ball valve (No.
23).
Line thermometers shall be installed in the collector
supply and return lines to allow for a simple
diagnostic check of proper system operation. On
a sunny day the hot water return line should be
approximately 5 – 12° warmer than the water in
the collector supply line. Compare the temperature
readings in the two line thermometers (No. 3).
