I've shot them a message to see what they say, but found identical looking ones somewhere else that specified 32mm was the internal dimension on the valve ends so would need 32mm od pipe. I suppose another alternative would be to not use standard waste pipe and just plumb it out entirely out...

Yeah I saw those, but one of the reviews say they don't fit 32mm UK waste pipe. I'm assuming that those valves have a 32mm internal diameter, but the external diameter of 32mm waste is more like 36mm I believe. EDIT might not be quite 36mm, but its more than the 32mm internal diameter of waste...

I'm looking at the possibility of installing a saniflush toilet (combined loo and macerator) in my somewhat frail parents house, and it would be nice to put a service valve on the probable 32mm solvent weld waste pipe close to the toilet to allow easier maintenance. Having a glance at the...

I quite like my smart meter, its currently saving me lots of money. I'm on the Octopus tracker tariff which as of February requires those switching to it to have a smart meter. Today I am paying 5.03p Kwh for gas and 20.99p Kwh for electric (price cap in my area is 10.23p gas and 32.72p...

The point in low loss headers is to allow the use of multiple pumps for different zones without them interfering with each others flow. In your case its so the multiple pumps for your zones can operate independently from each other, and also not interfere with the pump running water through the...

LLH can reduce the boiler efficiency as it can cause the return temperature to be a bit higher which reduces the ability to condense, but the heat doesn't just disappear in a LLH - if your calculations are correct 30Kw for 2 hours is a big amount of energy going somewhere. Maybe you have some...

Are you sure your gas usage calculations are correct? If the boiler was running 65 degree water at a full 30Kw constantly for 2 hours that heat has to of gone somewhere into your system, and I'd think that would be noticeable.

I would assume you will just become an Octopus customer. I was with Avro Energy before they went bankrupt and Octopus took their customers on. Once I was moved over and my octopus online account became active I noticed the option to ask for a smart meter on the website and thought I'd go for it...

I'm with Octopus and have a smart meter, and to be honest the anti-smart meter arguments are a bit lost on me. My meter works fine, I don't have to submit meter readings, I've been able to make a few pounds with the demand reduction scheme they ran this winter, and I don't fear my meter being...

Looks more like a microbore pipe bender, probably for 8-10mm pipe.

I thought the extreme right was quite possibly in some state of twist that may not of given the view across the cable at its fattest dimension - hard to establish without more of the cable in shot. Also given that cable is moving backwards away from the post perspective could throw out the...

I'm going to agree that it looks like X1.3 the diameter of a M20 bolt on the outgoing cables to houses making that a 35mm2 cable. The incoming cable to the post definitely looks much larger, and I still think in all likelyhood that is 95mm2, which to my mind would make sense given its feeding...

Looking at the right-hand edge of the right hand overlay I would be thinking 1.5 times the bolt putting it at possibly 50mm2, but then the left end does look more 1.3 times and 35mm2. I think the key thing to bear in mind is that the bundle is 4 cores and not perfectly round in cross section...

The first document I found describes the use of M20 bolts through 22mm holes in the posts. Now assuming that your post is using the same standard looking fittings and M20 bolts I present this terrible piece of image editing consisting of a coloured in bolt cut, rotated, and pasted over the...

It does seem strange given how specific all the other parameters are. I presume its to give different cable manufactures a little leeway in their designs using slightly thicker or thinner strands to meet the required CSA.

A little bit more google of ENWL documents found this document about ABC cables. On page 15 there is this table which has some maximum diameters of bundled cables (also including the possibility of 50mm2) and its interesting how little the diameter of the cable bundle increases for quite big...

I assume they are applying metric conversion in the document.

I also found this document from Scottish Power which I found interesting. When I had my house supply unlooped from next door the DNO dug up the main supply cable so that they could run a new supply to next door, and from looking at the pictures in this document I'm quite confident that the main...

I wonder how much of the L N loop impedance occurs within the transformer windings?

Quick google found this document from electricity northwest on overhead supplies. Makes mention of 35mm2 and 95mm2 cables.
