    Sudden Loss of Hot Water Pressure
    I had good hot water pressure in my flat for many years, until Tuesday when I found the hot water was only trickling out of the shower, and all the hot water taps in the flat were about the same. I also found out that there was an emergency on the estate and Thames Water were out fixing the problem on Monday. Could there be correlation? It is now day two and Thames Water simply say that they only deal with cold water pressure. Can anyone advise on how I can resolve this?

    Is there good pressure on the cold water side ? If so some time when the plumbing system is worked on sediment will loosen up , and then can clog plumbing parts. Can not understand why the men that looked @ plumbing , would not take few minutes , and check it out. You may Have a hot water tank issue? Hard to solve over the internet.

    Yeah, if there is good cold water pressure to the home then the problem is probably located at the cold water feed into or out of the water heater. Here, if this is the case, then there is a possibility that some sediment that got disturbed at the water main (s) clogged up the HEAT TRAP NIPPLES of the water heater. You or a plumber would need to check these by removing them from the in/out connections to the water heater.

    You could attach a hose to the drain on the water heater and open that wide open...see if you have good volume/pressure or poor flow. If you have low volume/pressure from the hose after say 2-3 minutes of running water then I suspect the problem is at the inlet nipple or the shut off going into the cold water feed of the water heater.

    Start there and then post back with questions/observations, OK?

    The water company may have caused the issue by breaking debris loose when they did their repair work. That debris entered on a cold line and that debris could have found its way into your water heater. However, you will never be able to prove this therory. In any case, first check to see if you get a strong flow/volume of hot water out of your drain spigot at the bottom of the tank. Back to you
