no water coming up the supply pipe anymore?

Question

We moved our en-suite around and as a result the hot tap supply doesn't run anymore. It did do before, and we have no leaks or disconnections, the water is in the pipe. But it is as if there is not enough pressure there. the basin has only moved 1' to the left and the pipe hasn't been extended. Why would this happen?
Any ideas? thanks!

we have a combi boiler, no water tank.

Answer 1

It's probably an air lock in your hot water system. However if you have a combi boiler then this is quite unlikely. If you have a hot water cylinder then this is most probably the fault. Try sucking on the pipe, or if you've got the tap connected then suck on the tap. If it's air causing the problem then after a few sucks you should hear it rushing through the pipework and the water should follow. Hope this helps?

Answer 2

Plastic Y pieces are often bad news, especially if you are using a cheap one from somwhere like B&Q. Sometimes you can find that brass ones are much better. You should not connect the dishwasher to hot water supply at all, and if the washing machine only has a single water inlet that must also be connected to the cold supply. There are good reasons for this: the main ones are that the dishwasher needs cold water for rinse and its hot water must be hotter than your hot water supply; and the washing machine will heat the right amount of water that it needs much cheaper than the cost of drawing it from your tank (as you say, it takes a long time and the machine's heater will be on long before the hot water arrives). First make sure that the rubber washers in your Y piece are all intact and in place. Then get some PTFE tape (often just called "Plumber's Tape") and wrap this around the threads of the pipe splitter. This tape in not glued but it does "cling to itself" which makes it interesting to handle. Make sure that you wrap it around following the direction of the thread (not across it) so that the tape sits in the grooves. About half a dozen thicknesses is usually enough. When you screw the pipes onto the taped threads this forms an effective waterproof seal. You could also call in a plumber. The fee of £70 or less to plumb in your machines isn't a lot compared with the cost of them. It's probably less than a family day out. You'll save money in the end by using the right water supply that the machines were built for.

Answer 3

sounds like you have an air lock in the pipe ........ connect a hose pipe to the hot tap and the cold tap turn on the hot and cold taps and the cold water will go in to the hot system and back to the tank ..... then turn off the cold and the hot and you should have water from your hot tap :) that is assuming that you have turned the gate valve back on ( by the hot water tank )

Answer 4

I had what sounds like a similar problem, how they fixed it was to attach a (shower) hose to the cold tap the other end to the hot tap turned both on, the flow of the cold unblocks any trapped air apparently.

It was a good trick that has now been used several times in my house.

Good luck.

Answer 5

Blocked from new joint efforts?
Tap/faucet damaged?
Debris forced into base of tap?
If there is water, as per, I, personally, would take it apart again and check all above.
If your pressure is low, check your boiler.... it may be low water pressure in the boiler (combi type) and that may cause an 'ERROR' in the system.
Usual (UK) pressure: 1.5 bar... when off and cold.
Good luck.

Answer 6

when you moved the basin you must have turned a valve off to the hot water ..other wise the water would not have stopped for you to disconnect ..turn this v alve back on

Answer 7

If it has service valves, as it should have, did you turn them back on? If it has fleible connections, are they kinked? If all ok, turn off the cold water, open hot taps from highest to lowest, then turn water back on slowly, turn taps off going from lowest as water comes through them.
