check for leaks. If need be, using a wrench, tighten the immersion heater another 1/4 turn or until the
leak stops, again being careful not to damage the threads or break the immersion heater. If you
cannot stop the leak, turn off the water pressure, drain the tank, remove the heater and try the whole
procedure again, this time using more windings of Teflon.

Note:
The immersion heater is in the left
end so it doesn't burn up because of a low water level. If you use the immersion heater, the person
who installs the electric heater must be a qualified electrician. You need to use an electricity leakage
protection plug and it should be grounded.)
