Low hot water pressure...


My neighbor and I live in a small 2 apartment building and share the hot water heater and was working fine up till about 6 months ago and since then we have noticed a slow and steady drop in pressure. Its so bad now that the hot water is almost a trickle and also will literally stop running at all for a few seconds every few minutes and then start back up with the typical low pressure.

Twice we have tried draining the tank and its always clear. Also a friend was saying that since the water is flowing from the drain valve properly that its not a problem with the tank itself (not sure how true this is).

I guess my big question is... what on earth would be causing the pressure to be so low and also why would it stop and start every so often? Cold water pressure is fine. Its a standard water heater... not sure how old.

Old steel pipes?
Old gate style shut off valves?

If we sat around waiting on the landlord to either fix/replace/research the issue we would end up smelling like 10 day old trash sitting out in the dead of summer. I been here for a year and still cooking out of counter-top griddle cause he hasn't replaced the broken stove and walking around on concrete floors just as long cause he never replaced the wet moldy carpeting after a flood.

How do you put up with such a landlord? Bargain rent or stuck on lease contract for a while?

If the drain cock works--turn it on---if it blasts out water--you have good pressure to the tank---if it runs slow----the problem is at or before the tank----

Let us know----

Could be a gunked-up energy-saving device on the hot water output at the top of the tank. Little marble that's supposed to keep the hot water in the tank until called for. Should be easy to close the cold side cutoff valve, disconnect the pipe to the hot side, dig the marble out, and throw it away.

Slightly increased energy (gas or electric) costs.
