I am trying to lift some old cork floor tiles in my bathroom but it is difficult. They are stuck down with adhesive on to vinyl tiles underneath. The Vinyl tiles are stuck to the concrete floor. The whole lot is very hard to shift using a scraper. I don't care whether I remove just the cork...

Thanks masona for your swift answer and the link to a fascinating article on the subject

I have several USA books which refer to nails by "penny sizes" e.g. 2d nail, 6d nail, 8d nail (presumably these are "old pennies") Can anyone help with converting these to British equivalents, please?

Just one other thought. You may want to disconnect the cable at the cooker end rather than the wall plate end, so that you can re-use it with the new cooker if it doesn't come with new cable.

There's no special problem about disconnecting, just be absolutely sure the supply is off. Check that nothing on the cooker is working. If your cooker control switch has a socket included check that it's not working either. Don't rely on the cooker switch, switch off the circuit breaker or...

The problem is not really about how to use a multimeter but rather a lack of basic electrical knowledge. You need to understand the relationship between volts, amps and ohms (Ohm's Law), the difference between a.c. and d.c. , a bit about simple circuits, etc. before you can use a meter to...

When doing a domestic rewire, is it usually possible to pull new cable into existing runs with capping and plaster covering or does it need new runs to be chased out ? Does capping come in various sizes e.g. for 1 sq mm, 2.5 sq mm cables? Would it be sensible to use oversize capping to...

Thanks for the replies. I've found some info in Which? magazine :- Q. My engineer told me that condensing boilers are expensive and unreliable. Is that right? A. Some of the first condensing boilers weren't well made and there were many problems which gave them a bad name. They've now...

I have been told by a plumber that condensing boilers will soon be compulsory (from next year?). He also said that they have a poorer reliability record than non-condensing types. Are both of these things true? I have a 15-year-old Potterton Flamingo II that still works fine. I have a...

I have to trim about 3/8 inch (10 mm) off 2 door bottoms to allow clearance for a new carpet. I think this could be done with :- a) circular saw b) jig saw c) handsaw d) power planer e) hand plane What are the pros and cons of these methods - which is best or is there another better...

A 45A mcb should not trip on 47A load unless it is on for a long time, so the mcb may be faulty. It certainly shouldn't be getting hot. I haven't got the regs and tables to hand but as a quick check go to http://www.tlc-direct.co.uk/Technical/Charts/VoltageDrop.html It shows that...

You also need 10mm2 cable from the MCB to the shower

Should have said Volts x Amps x Power Factor = Watts = True power

You've got it the wrong way round. Volts x Amps = Voltamps = apparent power (ignores phase angle, power factor) Volts x Amps x Power Factor = true power (allows for phase angle)
