Water Heater Tips Video
VIDEO SUMMARY
Where the copper pipes attach to the top of the water heater, dielectric unions should be used. When you connect two dissimilar metals, such as copper and iron, in the presence of water, you can get electrolysis. This can cause corrosion of the pipes and eventually a leak. The dielectric union separate the two different metals with a rubber washer. A side benefit of these unions is you can disconnect the pipes quickly with the union's nut.
If you have a gas water heater, the vent pipe must be the proper size to vent the exhaust. If this vent pipe is too small, there will be a backup of the exhaust fumes.
Replace the pressure relief valve when replacing the water heater. Do not try to reuse the valve from the old water heater.
Follow these tips and you won't be in more "hot water" over your installation.

i know the a gas storage (30-40 mj/h) vs gas continuos flow (200 mj/h) use
about the same amount of gas in a dollar sense (if any thing the gas
storage is 2 or 3 dollars cheaper. i would assume the a similar situation
with the power cost and use of an eletric. If u have a hwu outside then it
take up no space inside the house. If its gas and the power goes out u
still have hot water. The sediment should be destroyed inside by the anode
and if u still want no build up of sediment the put a filter on after the
gate valve. I know its just an add but get the facts right. My figures are
from Australian conditions.
