Water tank not filling up, no water coming out of the hot water taps

Hi so I’ve emptied the water tank to sort a pipe that runs the hot water, Now turned everything back on the tank in the loft is filling up but the tank for the hot water doesn’t seemed to be filling as there is no water flowing to the hot water taps? Just seeing what could be the problem? This question has already been posted and answered with the send cold water under pressure up the hot water tap, in my case, I have done this seveeral times without success, are there other ways to clear this issue? Cheers **Further Update** Left it overnight while I had a think about it, the plan was to see what my brain could figure out today and if nothing came good, call a plumber out. Well, first think this morning, turned on the hot tap in the kitchen, it’s working, the pressure does still seem to be a little less than it was but not massively so hey, I’m chalking this one up to a win. It was effecting all the hot water taps in the house so I thought i’d better give em a try, all taps now work, the one exception, the shower is trying to pump with no water at all andf sounds terrible, i’m tempted to let it carry on screaming at me till it gets a hold of some water but probably not the best idea – it has hot and cold feed, works fine on cold but when I turn it to hotm within a few seconds its screaming again, Ideas? Cheers

Answer-

Based on your updated situation, it seems the main issue with hot water has resolved itself overnight, which is great news. However, you’re still facing a problem with your shower. Let’s break this down and consider some possible solutions:

1. Air in the pipes: The most likely cause is that there’s still air trapped in the hot water pipes leading to the shower. This is common after draining and refilling a system.

2. Shower pump issue: If your shower has a separate pump, it might be struggling due to the lack of water or air in the system.

Here are some steps you can try:

1. Bleed the shower system:
– Turn off the shower pump if it has one.
– Open both hot and cold taps fully.
– Let them run for a few minutes to push out any air.
– If you have a handheld shower head, hold it at a lower level than where it’s usually mounted to help gravity assist in clearing air.

2. Check the shower pump:
– If your shower has a pump, make sure it’s properly primed with water.
– Some pumps have a small bleed screw. If yours does, you can try carefully opening it to release trapped air (have a cloth ready to catch water).

3. Gradual approach:
– Instead of switching directly to hot, try gradually moving the mixer from cold to hot. This might help push air out more gently.

4. Check valves and filters:
– Your shower might have inline filters or check valves. These could be blocked with debris stirred up when you emptied the system.
– If you’re comfortable doing so, you could try removing and cleaning these.

5. Wait and repeat:
– Sometimes, these issues resolve with time as air works its way out of the system.
– Try running other hot taps in the house, then attempt the shower again later.

6. Professional help:
– If these steps don’t work, or if you’re not comfortable performing them, it might be time to call a plumber. They have specialized tools and expertise to diagnose and fix more complex issues.

Remember, don’t let the shower pump run dry for extended periods as this could damage it. If you hear it “screaming” or running without water, turn it off promptly.
