Hi, I have a clog in my kitchen drain. I have bought a high pressure manual water blast/suction "plunger". However, I cannot create a sealed pipe, as there are two sinks, and also two outlets for the dishwasher and washing machine. I tried to unscrew the various compression fittings, and block...

Hi, What is the best type of paint for communal areas in a block of flat. We get some marks due to people moving in/out, deliveries etc. I am considering using Dulux Trade Diamond in a mid-grey colour to keep the walls nicer for longer, but is there anything better on the market...

Hi, I live in a block of flat, with 33 flats. The roof is flat, and quite large. I think the usable surface for solar panels would be at least 150 m2. We pay around £4,000 for communal electricity per year (communal lights, lifts, car park etc). We use around 3,000 watts per hour...

Hi, I live in a block of flat with 33 flats. The existing carpet is around 11 years old, and is a bit worn out in some places. We also have carpet in the staircases. I believe the existing carpet is: http://www.jhscarpets.com/range/signature-ii Apparently, it was typical mid-range...

Hi, My block of flat has 64 round wall communal lights, using 2D 4 pin tubes (16w). Most lights are also emergency lights (with battery packs). If we want to convert those to LED, is it just a matter of buying a 2D LED lamp to replace the fluorescent tube? Something like...

Hi, We are currently installing CCTV in my building. The recording equipment will be in the underground car park, so not easy to get a telephone line there with ADSL. Therefore, I am thinking that maybe we could use homeplugs between the underground level and ground level to network the...

Hi, My block of flat has two pedestrian gates leading to a car park. They have Locinox LAKQ U2 locks. Unfortunately, people have to remember to lock the gate after opening it. Is there a quick solution to make the door self-locking, i.e. a key is required to open it at any time...

Hi, I live on my own in a block of flat (build around 10 years ago). My yearly usage was 36 to 50 m3 in the previous years, but has now increased to 100 m3 according to the last bill received, based on water meter reading. Online estimators say that I should use around 50 m3 per year...

Hi, I would like to install multiple PIR detectors in a large residential car park, and control them all through a single control box/single timer (to switch about 20 fluorescent tubes at the same time). The PIRs will be hard to access, and therefore it would be better to adjust the delay...

Hi, I live in a block of flat that has a large underground car park. In the car park, all the fluorescent lights are always on, so the electricity bill is quite large (about £2,500 just for those). We have about 60 tubes (58w each). I was thinking about getting some motion sensors to be...

Hi, I have electric underfloor heating in my living room/kitchen (one cable, wattage unknown) and when switched on, the spur switch (with a 13A fuse) on the wall becomes very hot, particularly the fuse section, and there is a bitter/fishy smell (like something melting). The electric board for...

Hi, I just moved to a modern flat that has Devi undefloor heating throughout all the rooms. The heating elements are build into the concrete floors (not visible even when carpets and underlays are removed). On the electric board, there is a Devi 710 system with several adjustment dials...

Hi, I am purchasing a flat with a Devi electric UFH (part of the concrete floor, was installed when built), and white carpets are currently fitted everywhere (not great for maintenance!). What would be the best replacement? 1) Thin engineered wood flooring with special underlay. Wooden...

Hi, I am buying a flat that has a Devi electric underfloor heating system. The surveyor says that "elements are located within the cement floor screed but couldn't be inspected due to fitted carpets". All rooms have Devireg 550 thermostats on walls. I have a few questions: 1) Is it...

Hi, I am buying a flat, and the home buyer survey just came back. The surveyor states that "hot water is provided by a Sadia Megaflow Moonsoon sealed and vented system, providing hot water at mains pressure. There is an associated Sadia pump and expansion bottle. Pressure was low at time...
