Inspect Fittings
Which fittings need inspection? Look at the hot line and cold line. They
are on top of the water heater. The cold line is on the right and the hot line
is on the left always. Inspect the T&P valve. The T&P valve is located on top
for some electric water heaters. All others will be found on the side of the
tank. It looks like a spout with a one inch movable lever. A piece of plastic
pipe may be connected to the spout, but not necessarily. Check the drain valve
which is at the bottom of the water heater. It looks like a standard outdoor hose
bibb. Also check the thermostat located behind a panel on the upper half of
most electrical water heaters. In order to check these areas, simply wipe a cotton
swab all around the areas.
Leaky Fittings
As already discussed, the problem areas for leaks are the drain valve,
heating elements for electrical water heaters, and the hot and cold connections
on top. The ball valves on hot and cold lines can leak around the nut used to
rotate the lever. This leak can in time destroy the tank enough to warrant a
new tank. If you notice water stains on and around the tank, do not forget this
hard to notice spot.
If you've followed some energy conservation advice
and installed an insulation blanket around your water heater, just be aware
that leaky fittings will be hidden beneath this blanket. Rusting may occur under
a blanket more quickly than without one. Do not insulate directly around fittings,
especially the hot and cold lines and the T&P valve.
