Difficult to know. It could easily be a blockage. It could also be insufficient fall on the waste pipe. If it worked once then became a problem the waste may have sagged. Why not ask your plumber to sort it out, after all you paid for a correctly functioning waste and if he is a good boy, he will no...

You could but it will not have much effect. How about connecting your outside tap if you have one to a hose and firing mains water into the system via a drain cock. It is crude but will give more benefit than gravity. Also you will be backfilling the header tank so you will need to take care not to ...

It makes no difference how long you've been in the trade when sizing gas pipes. You will need to know the heat input of the appliances and the length of pipe. Without theses details you introduce an element of risk. Dont take risks with gas. Corgi state that gas pipes must be sized according to the ...

Sounds to me like your jumpers stuck. You could try opening the tap and giving it a whack. Also try warming the tap up by pouring very hot water over the tap body and then give it a whack. If that gives no joy then have it appart.

Thiscould be water hammer caused by the ball valve patially closing. Shin up in the loft and see if water is coming from the outlet of the valve. You could put a bit of upward pressure on the valve arm to force it closed and this should indicate whether the valve is the source of the noise.

Yes, but bear in mind that a bathroom is a special location from an electrical point of view. If a tool is needed to access the pump I think it counts as outside of zone 2 but check this. Your switch gear will have to be ipx4 if it is located in the bathroom, so you will need to consider this too.

Chances are that its mains. You need mains for your drinking water so the kitchen tap should be mains. Turn off you main stoptap and run the bathroom cold supply. If it is dead, then you bathroom is mains. Bear in mind that your hot could also be mains unvented. This will run for quite a while as th...

You need tools.

To check flow rate you need a wier gauge. You can get an idea of flow rate with a 2 litre measuring jug and a watch but not very accurate. For pressure you need a pressure gauge. Flow rate is more important than pressure. Check with the shower manufacturer.

No Squire but....

Your thermostatic rad valves may cause water hammer unless they are bi-directional. If you can connect as existing it might save you some agro.

No that wont be fine.

To size a gas pipe correctly you need to know the heat input of all appliances running off that pipe. You also need to know the length of pipe run. To that length you need to add 1 metre for elbows and 1/2 a metre for pulled bends. These figures are required to ensure that there is sufficient gas av...
