Could it be a previously mis-read meter?

1. Locate your internal stop tap, fitting a new one if necessary. 2. Turn off the water to your property using the internal stop tap. Make a note of the meter readings at the same time. 3. Leave water off for as long as possible. (Or repeat exercise). 4. Before turning the internal stop tap...

1. To turn the syphon round you have to have an alternative hole on the left hand side side of the cistern to fit the handle through. Not all cisterns have this. 2. You may also find that the cistern fouls the overflow pipe, in which case you have to change the syphon as well for one with an...

1. For a condensing boiler to operate at high efficiency, the RETURN temperature at the boiler should not exceed 55 degrees. At or below 55 the boiler will work in condensing mode. Above 55 it won't. 2. With a condensing boiler, the temperature drop across each radiator should be about 20...

1. Danfoss or Pegler. Seem fine but have only been using for a couple of years. 2. You can just replace the head by undoing at the knurled metal ring. But: 2.1 The heads are quite expensive. 2.2 Unless the quality improves, you may have the same problem in a few years.

1. If you mean an electric "greenhouse" type radiator, then assuming you have removed a hot water cylinder to fit the combi, then there should be enough space that the heater will not interfere with the boiler. 2. However, the cost of running such a heater is likely to exceed the cost of...

In my opinion the quality has deteriorated significantly in the last few years. I have had a number just come to pieces, apparently in the same way as yours, with the adjusting knob detaching from the body. After 30+ years of their being my favourite TRV I no longer fit them.

1. It would help if you could post a picture of the existing shower. 2. If you know the exact make and model you may be lucky and find an exact replacement (same make and model). Even so, a lot will depend on how it was originally fitted, in particular whether inlets are accessible and with...

Just be aware that if it is a mid-position valve in the Y plan system, you may need an automatic bypass valve fitted when you change to S plan. With the S plan, you could have the hot water valve closed, and if you have TRVs on all radiators, then the central heating circuit is effectively...

1. The boiler heats water for the central heating, and also for a coil inside the BoilerMate. 2. Hot water from the boiler flows through a coil inside the BoilerMate. The heat from this coil passes into the main body of water inside the boiler mate and keeps it a high temperature. 3. When you...

Looks like the seal. Try fishing it out with a hook of some sort (old wire coat hanger cut and bent?) and see if it can be re-used.

1. Looks to me as if the 90 degree elbow is missing its sealing ring. 2. The black pipe should have (from black elbow towards open end): 2.1 The white knurled nut from the white elbow. 2.2 The orange coloured plain washer from the white elbow. 2.3 A black rubber sealing ring. E.g. McAlpine...

1. Make sure any tap you buy is suitable for the hot and cold water supplies. 2. If you have a combi boiler or an unvented hot water cylinder, you should be OK with pretty much any mixer. 3. If the hot water is from a vented cylinder you will almost certainly need a mixer where hot and cold...

Try re-installing the radiator and running the system. With it running, turn down the lock-shield valve on the problem radiator and see if the bottom centre starts to heat up. If it does, then with both valves fully open, water was going straight through too fast without losing heat to the...

No. Sounds as if you have a heat only boiler running a sealed system. If so the filling loop will be elsewhere. Look for a braided hose running between two pipes, with a valve at each end of the hose. Typically under the work top below the boiler or in an airing cupboard. Exact model of...

Pegler full bore lever valve. E.g. Screwfix 11085 for 15 mm or 18343 for 22 mm. Check size of incoming pipe first.

1. Yellow lever is gas. 2. Look to the right of the gas valve. There should be two pipes each with a 1/4 turn valve, screwdriver operated. Open one by turning the screwdriver slot 90 degrees. Then open the other, slowly, in the same way. Pressure should start to rise. When is reaches...

Three possible reasons for central heating header tank overflowing: 1. Fill valve not shutting off. Per. dilalio above. 2. Central heating pumping over. Could be various causes, including blocked system feed, pump on wrong setting. Tie an empty jar under the vent and see if it gets water in...

1. Are you sure the meter is cubic meters or is it cubic feet? 2. No other gas appliance (e.g. hob) used during the measurement week? 3. Photograph of meter would be useful. 4. A 38 year old back boiler would be lucky to have an efficiency of 50%. You might want to do the cost / benefit...

In which case, first try just tightening the back nut. Turn the water off, remove the top of the flexible hose and use a box spanner to tighten the back nut. Spanner = Screwfix item 844RH or similar.
