MM Put a plastic bag over the external outlet of the prv pipe for a day and see if you collect any water. Does your pressure rise significantly when the boiler is in operation? Gooba Your expansion vessel is most likely fooked. The cheap alternative, as suggested is to fit an external one...

The police should check the local garden centers as it might be being used as part of an irrigation system :D :D

You only have one water main comming into your property (I assume). When the hot tap is open you will get the full flow through the boiler to the tap. When you open a cold tap in addition the water flow will be split between the two and therefore the flow reduced to both taps. There are other...

The expansion vessel should not be full of water. There is a diaphragm inside and if you momentarily push the center of the schreader valve you should hear a small amount of air escape. If wheen you do this you get water, you will need a new ex vessel or fit one externally. If the diaphragm is...

The normal shower delivery should be around 13 l/min so looking at your figures, it looks ok. Take a look at the Aqualisa digital Quartz combined bath filler/shower. If you can afford this product, it is money well spent and comes with a 5 year guarantee.

See FAQ about re-pressurising expansion vessels and testing if it is knackered.

It has an internal condensate pump also.

My strongest advice is to get the plumber out of your house ASAP and get somebody that knows what they are doing :shock:

Ball valves sometimes have a tendency to leak from the spindle. If you decide on these you should ensure that you purchase full bore ones or you may suffer from flow problems.

The thread size is normaly 1/2" BSPT and I assume you refer to valves with a built in drain cock. You will need a special allen key (Available from plumbers merchants) to remove the old valve and a spanner to tighten the new TRV. You will need to fit an auxilary drain cock assuming that the...

After would ensure that there is no air in the pump.

it sounds as if you have created a second problem. I think that you may be looking at a new pump and most likely a new fan. The fan will need to be changed by a RGI as it forms part of the flueing system.

My guess is the electrician in order to get the socket where he wanted it :lol:

Persist with the screw in the centre of the pump - it opens anti clockwise. Do this with the boiler off and until you get a small trickle of water out. When filling the system, vent the downstairs rads first. Steve

I would have done it for a tenner :D :D :D

Looks ok to me. What sort of boiler/system do you have

Did you vent the pump once replaced? The pump is knackered and needs replacing.

How about using anti vandal paint - the stuff that remains sticky

The problem is not getting the fitting but getting the insert. I had to get one made on a lathe when I had a similar problem.

Open the lockshield valve a little.
