Roof leaking
\
This complaint is usually made during or after wet weather and normally soon after
commissioning a new water heater. The movement of persons on the roof during
installation can crack roofing material if the load is borne on specific points or the roof
material is brittle.
Replacement of damaged roof materials is essential. Use of a woven plastic roof sheet
below the collectors will make water penetration more difficult in the future. It should also
be established if water is penetrating around the pipe or sensor joints through the roof.
Moisture under the collector glass
Small amounts of condensate on the underside of the collector glass are not a sign of
collector failure. The condensation is formed from humid air condensing when the collector
cools down. Because of high temperatures within the collector, ambient air is transferred in
and out of the collector through drain holes. Note: The collector is not hermetically sealed.
Hot water plumbing leaks
If hot water has not been used for a period of time, feeling the temperature of the hot water
line may give an indication of water flow if the pipe is warm. The method of checking for
plumbing leaks is:
1. Turn off the stopcock on the cold water supply to the water heater.
2. Open a hot tap to ensure the flow of water stops. This will confirm the stopcock is
operating correctly.
3. Turn off the hot tap.
4. Turn on the stopcock to make up the water pressure in the cylinder, and then turn the
stopcock off again.
5. Wait approximately 5 minutes then do either of the following:
a. With your ear close to the stopcock turn it on slightly and listen for any water
passing. If there are no leaks, water should not pass.
b. Open a hot tap while listening for any pressure release. If there is a pressure
release there will be no leaks in the plumbing system.
Mixing or crossed connections
If an automatic dishwasher, washing machine, flick mixer tap, tempering valve or
thermostatic mixing valve is installed there is always the possibility that the cold water
could mix with the hot water through a faulty or incorrectly installed valve. This is referred
to as a cross connection. The complaints of insufficient hot water, water too cold or
excessive discharge from the T&PR valve may be attributed to a cross connection. The
method of checking for a cross connection is:
1. Turn off the stopcock on the cold water supply to the water heater.
2. Open a hot tap. If water flow is persistent and cold a cross connection exists.
