No hot water!

[Mamps]

Hello
I hope someone can help me.
I had a new team shower pumb attached to the taps in my bath. It hasn't been working for a while so i've just replaced it. I turned the hot and cold water off in the loft, turned the electricity off, took the old pump off and put the new pump on, then turn the hot and cold water back on - without turning the electricity back on, check the taps and the pump for any leaks. There was a leak on one of the pipes from the pump, so i turned everything off again to take the pipe off and try it again. Again i turned everything back on (apart from electricity) but now the hot water doesn't work. it kind of dribbles out of 1 tap. If i put more than 1 tap on - only one dribbles and the others.
Have I got an air lock? if so, how do i get rid of it?

Please help!!

You have either and airlock or you have snapped one of the valves you shut the how water off with in the "OFF" position.


To clear and airlock can take time and patience but a quick trick to try is to connect a hose between you hot and cold washing machine valves and turn them on.

Thanks for that. Just tried something that has the same result (i think) Turned on the kitchen hot water and blocked it with my hand and then turned the cold water on still blocking the tap. This seems to have got rid of the air lock.
Thanks!
