No Hot Water Pressure...

A few days ago, I replaced the pressure release valve on my 5 year water heater. The seals in the old valve had worn out. The house is over 200 years old and the pipes are very old as well (don't know the age).

After bleeding my lines, I noticed I had no hot water pressure going to my kitchen sink. It was the only faucet in the house I had no pressure. I checked the faucet, but nothing was clogging it there.

I read online that I should wait a few days for the rust and sediment in the line to dry up and then re-bleed the lines again (after emptying the water heater). I did that. After bleeding the lines, I now have no hot water pressure anywhere in the house.

The cold water pressure is fine throughout the house.

What could be causing this?

How can I fix it?

Thanks!

Chances are the HWT has anti-percolation valves and they probably got gunked up with sediment.

I should stop calling it that and call it what much of the industry does, namely heat trap nipples.

Do I need to call in a plumber for the heat trap nipples? Or can it be a DIY project?

If you are capable of removing the piping from the top of the water heater, you are probably capable of removing the heat traps.

Gate valves failure mode is to have the gate break off from the shaft of the handle. So, then, you can't really retract the gate. It's possible you have galvanized nipples or heat traps, and those can corrode or the trap valve stick. If you open the drain valve on the tank, does any water come out?

Thanks, everyone for responding. Turns out it was just sediment in the lines.
