Should I Get a New Water Heater


Looks nice! I really need to get a new water heater as mine has always been horrible at keeping a consistent temp and is 16 years old. Not as old as yours was but pretty good for modern stuff that doesn't seem to last like they used to.

I actually flush mine from the drain valve with a garden hose using the air pressure fed into the tee. My tee is on the cold side so that the air coming in will stir up the sediment but really don't think it matters all that much which side. I blow it totally dry through the hose on the drain valve into a nearby utility sink.

How do you know flushing is actually helping? Do you see solid particles coming out? How often do you flush it out?

I think I saw one on This Old House or similar years ago that was made like a chain with long links to allow you do insert it when you only have a couple of feet clear above the tank.

Anyone know where to buy these? My Google Foo didn't find any.

I enjoyed reading this as my water heater was manufactured in 1969.

I have a funny feeling the drain will be non-functioning on it as well and should probably start considering a replacement.

Wow, 1969... you've got your $'s worth out of that one! I installed my own new water heater this past weekend. Much more efficient than the old one and with the electronic controls much better temp regulation. I decided not to install a permanent tee for connecting an air compressor for periodic flushing since I used flexible water connectors. Easy enough to just disconnect one and connect up the air line when I need to.

When I took my old WH to the dump some of the gunk came out in my truck bed. The tank was laying down and the gunk flowed out of the open water connection nipples. It looks like a cloudy gel with white mineral flecks. Not sure there is a definite way to measure if flushing helps or not but it makes sense that it does. The gunk probably hurts heat transfer from the burner to the water and perhaps coats the thermostat if it gets deep enough. I can't say what it looks like while flushing because the hose end is down in a drain pipe but I bet if you flushed it to a sink you'd see cloudy water.
