I am currently living in a four storey building where the intake box for the communal stair lights is under the stairs between the ground and first floors. Possible malfunction of the timer to switch on and off the lights in the stairs persuaded the electrician to fit LED lights and leave the...

I have watched more youtube videos to understand better central heating systems and establish checking procedures. With them I managed to identify the problem. The ball cock valve in the small tank in the loft was stuck. The tank emptied after filling only some of the radiators and the boiler...

The comment from Regsmith was most helpful. I have switched on the hot water and central heating and noticed that now the boiler does not ingnite. I checked the pump and loosen the screw from the top to remove possible airlock, then restored it to its original position. After a while the pump...

Thank you for the replies. All extremely useful in clarifying the problem for me. I have watched a couple of videos on youtube and now the difference between the two problems I have experienced in the past: - the air lock in the hot water tap and - the cold radiator and the vibrating...

Thank you very much for your reply The pump does not seem to work anymore, and for over a year. I intend to extend the house in two years time and decided to deal with the pump then. Consequently the shower pressure is just normal, as if there was no pump. Hot water is running normally in...

The heating in my house has been switch off during the summer months and the boiler checked in September. In September all the radiator warmed up without problem. Today, however, the radiators in the ground floor did not do so and there was a vibrating noise around the emersion heater. Few years...

Thank you for the information. I wanted to calculate the optimal position for my dish from first principles, but unfortunately I cannot find information on the precise location of the satellite. I found the required link...

They forgot the earth wire above the false ceiling. In extensive projects it is difficult to change builders half way. There is no easy way of assessing fees fairly. All that remains is to supervise the work as closely as possible. Thank you all for all your help.

The house is semidetached. Unfortunately the side wall faces North West. I am most grateful for all your help. You have educated me. I am a Doctor in Mathematics with limited practical knowledge.

There was an earth wire. The old fuse box was replaced with a new one. The builders removed the old fuse box and installed a false ceiling leaving the earth wire above it.

The flat is one of ten along an opened balcony. The fuse box is inside the flat and the electrical box is in the communal stairway. The builders run the earth wire from the fuse box, through a hole in the seating room wall to the balcony, below the gutters passing three other flats to the...

The house faces South West. If the dish was fitted at the back of the house close to the gutters, facing South East and upwards, is it likely that the roof will obstruct reception? The roof is at an angle of around 45 degrees.

Thank you for all the replies. I hope you do not mind if I ask related questions. Ericmark's reply suggests questions: 1.- Does the location and length of the wire deteriorate reception? 2.- The work of moving the dish from the front of the house to the back and clipping the wire will...

If there earth wire became disconnected from the box or was physically damaged would be property become more exposed to possible fires? If a fire could be attributed to a faulty electrical installation insurance companies are unlikely to pay for the damage. Fires in my building have spread...

TV reception in my property is extremely bad due to very tall trees outside my home. I would like to move the satellite dish from the front to the back of the house. I will not be able to change the location of the wire's entry into the house because to enter the seating room it would have to...

Builders have been refurbishing my flat. As part of the work they had to rewire the entire flat, change the fuse box and lower the ceilings. The fist thing they did was to remove the fuse box and fitted the false ceiling. After re-plastering the flat, installing a new fuse box, fitting...
