    How many 'rafters'?

    I am absolutely gobsmacked by your advice. Not because you are wrong but, assuming you are right, it is difficult (for a layman) to believe the amount of support that three pieces of 0.8mm thick plastic (total weight possibly 2kg) require. I appreciate the point made by an earlier author about...

    How many 'rafters'?

    Thanks for the ideas. John D - The recommended way to attach the plastic to the wood is every fifth corrugation hence I would have to double the amount of wood used if I turned it round.

    How many 'rafters'?

    Thanks for the advice. Here's a picture which will hopefully explain my question better.

    How many 'rafters'?

    I am putting up a lean to roof using corolux corrugated sheets. Not sure yet whether it will be the miniature or 3 inch profile. The width of the roof is 180cm. I will be using 5 purlins supported by (what I believe are called) rafters at either end. The purlins and rafters will be 45mm...

    Plastic Corrugated Lean to Roof

    I am planning to build a small greenhouse (ish) between my house and a boundary wall. For a raft of reasons I cannot put an ordinary green house in that space. I intend to use Corolux corrugated clear sheets. I am confused about the wooden frame to which I will attach the plastic. I assume...

    Electric Motor Capacitor

    Thanks very much Zipper. I think you may have the answer I need. I was not totally honest. I got this shredder as a dump and realised from what little info I had that there should have been a capacitor in circuit but did not why. I think I can move forward now. Thanks again.

    Electric Motor Capacitor

    Can anyone tell me what function the capacitor connected to an electric motor performs? I have an ALKO garden shredder which runs forward or backward - apparently randomly on switch on and I am guessing the problem could be with the capacitor. It is single phase, 1100watts. Cheers

    Mains Hot, Gravity Cold

    Thanks very much for all the replies, particularly the final one which puts a lot of this in perspective. I agree to a certain extent re not a very good job. Unfortunately my daughter's partner has good ideas but does not necessarily always do his research fully. I think the idea of running...

    Mains Hot, Gravity Cold

    I think I have a common problem of hot water coming from a combi boiler and cold from a header tank. Hence when using a mixer switched to shower there is very little control of the hot water flow in order to have a reasonable temperature. Will a check valve in the cold water feed just before...

    Water Pressure Meter

    Yep Discovered that even though it is a block of flats in London sure enough there is a header tank. So is there any way of overcoming this pressure difference. I think I have heard of non-return valves. The head is about 10 metres so I am guessing the cold water is about 1 bar pressure.

    Water Pressure Meter

    gasafengineer Now I understand your earlier post. I thought you were just being sarcastic because I am tight fisted. I am not in London but I will get her to check. It is a block of flats so I am expecting it to be mains. Cheers

    Water Pressure Meter

    The problem is that when switched to shower to get a temperature which is usable the cold water is fully open and the hot water control is open the merest touch. Hence the flow is not particualary good. The hot water is set at 65 degrees and yes I have told her to turn it back to 50 when she...

    Water Pressure Meter

    D-Hailsham. It is a combi and the cold is mains pressure so I agree the pressures should be the same. However having taken flow rate measurements there is definitely something odd. If you are interested the flow rates through their normal bath/shower mixer unit are as follows: 6mm...

    Water Pressure Meter

    I do occasional plumbing for my kids and there is the usual problem (so I believe) of different pressure for hot and cold water fed to the shower. I would like to measure the pressure of the two feeds but buying a water pressure meter would be a waste of money given it may never be used again...

    Odd flow in bath/shower mixer

    A bit long winded but please bear with me. I fitted a Cross head Bath shower mixer (bought cheaply from Tool station) for my daughter, living in London, about 9 months ago. It is fitted with a 6mm shower hose. When switched to the bath the flow rates are Cold 21L/min, Hot 8L/min. When switched...

    Toilet Waste

    I have replaced three toilet bowls and cisterns over the last 7 years. I had to remove the bathroom one because of a leak on the inlet side (don't ask why that is a much longer story). When I have replaced it temporarily I noticed that the outlet where it joins the plastic waste pipe was...

    Gas Hob

    I fitted out my kitchen 3 years ago and did it all myself except the worktops which I paid a professional to fit. He fitted the sink and gas hob into the worktop using the supplied 'mastic'. I noticed sometime later that the hob was not fully in contact with the surface at the front and rear...

    Power Plungers for bath waste blockage

    Reading the reviews for these tools seems they are sliced bread etc... Before I buy do I need to ensure that the overflow on bath and sink are blocked to stop pressurised water escaping? And of course do you guys think these are good or just a gimmick? It is to be used on a (probably) 40/50 year...
