Oh Roger! Another absolute belter my friend. Especially loved the bits about Caesar’s piss and the American desecration of the English language. But all joking aside, there was an amazing amount of interesting information in there; even stuff I didn’t learn when doing my chemistry degree many years ago! Loved it. Please keep ‘em coming 👍

Great video Roger! Educated me and gave me a good chuckle too. Please do a video on the different types of water softener please. Very very hard water here and I think we're going to have to give in and have a salt softener as its ruining taps, etc.

[@sarge9733]

I already loved Roger and his teaching skills, but the snidey little dig at 'Flat Earthers' just made me love him even more. 😆

[@prenticedarlington2720]

Very entertaining. However, one mistake: In 'the continent' (eg: France) expanding water in hot water tanks is Not allowed to travel back down the cold feed. The excess water is either vented to the drain (via a 32mm waste pipe) or to an expansion vessel as you described. Every tank has to be fitted with a 'groupe de sécurité' which incorporates a pressure release valve (to a drain), a non-return valve and a tap. Enjoyable video, though!

[@peterremke]

I live part time in Scotland's highest village. The weather is severe. Learning the hard way, I switch off the Toby in the street, drain my tank, leave my house stop cock and all taps open in winter when I'm not there. Still I come back, fill up my tank and there is a little pipe that has burst under my bath. I know now that is because the pipe is going ever so slightly upwards, water is trapped and bursts the pipe which is not a biggie, better than having left water in the tank and flooding the whole house for weeks. Never mind, the hotel next to me had three burst pipes this winter while their heating was ON! Good to find out about hard and soft water, airlocks and expansion tanks etc. Vey informative for me as a layman. Presented with good old English humour.

Thanks Roger, great video. Having moved to a house which is on a private water supply earlier this year I must admit my water/plumbing knowledge had to get up to speed fast! This has been a really helpful addition. Cheers!

[@gdfggggg]

Plumbing can be quite complicated. I’m not a trained plumber but trained on pneumatics and Diesel engines, similar stuff. I switched over to building about 18yrs ago and after working on plumbing I’ve concluded that you need to be on the ball, cause it either won’t work or there will be catastrophic consequences. Sometimes us builders need to just get on with stuff and employing a trained plumber to crack on just isn’t an option. I’ve had no choice but to learn and get on with it. I’ve got a Boilermate3 boiler in my house and was insured with British Gas; they didn’t know how it worked; I fixed it myself in the end. I’m currently working in a 4 storey Victorian house with 6 bathrooms, 100yrs of pipe mods and we sussed it out removed all the lead and improved the water pressure. I think sometimes us builders deserve a little bit of credit. There is an assumption that we’re a bit thick. Training is always a good idea though.

[@bimble7240]

0:08 Are you putting PTFE on compression fittings ? or am I seeing things?

[@SkillBuilder]

Yes wrapping the olive with a couple of turns of ptfe is a belt and braces move. Some people use jointing paste which clogs the filters in the valve. I use PTFE and it never leaks. It is a well known trick among plumbers.

[@bimble7240]

@@SkillBuilder I have only seen it done twice before so it would be interesting to know how many plumbers do it. The first time I saw it some DIY wonderboy had connected 22mm to 3/4" copper with 22mm rings on a mains feed pipe. He had overtightened it to try to get it to seal on the 3/4 pipe then wrapped it with PTFE which worked, for about 3 years, but then it failed catastrophically and flooded the bathroom with over 30mm of water and part of the bedroom next door. Fortunately it was discovered fairly quickly, but the laminate wood flooring and the basin vanity unit had to be replaced. Which is why I never do it.

[@paulhaggett3710]

Wow, that was interesting! I wasn't expecting that

[@SkillBuilder]

Me neither and I made it

[@johncoppock3823]

Many thanks Roger for great lecture. Can you do a bit more on airlocks some time. They do seem to defy common sense. A real airlock doesn't normally have a beermat over the end of the pipe. So I assume it's surface tension that holds the water together. Therefore the diameter of the pipe is important. Could you do a demo then for a couple of different dia pipes, say 15mm and another different size, as to what height of water they will support. It's majic! Thanks in anticipation. Also a bit of education to avoid airlocks - always open the valve furthest from the supply first and then work back towards the supply. Thanks again.

[@Bloated_Tony_Danza]

I could listen to Roger talk all day long. He needs his own channel

[@UberAlphaSirus]

I can't fault you and Clevit. Glad I subbed to you two.

[@johncoppock3823]

Great video. Can you do one sometime on surface tension and how the diameter of the pipe affects the chance of airlock (assume the smaller the diameter the more likely the airlock because of the relative increased effect of surface tension in a smaller diameter pipe). You can repeat the glass test to do that but use a piece of clear tubing and no mat on the lower end. See what column heights different diameters can support. The maths for surface tension is I guess fiendish but I'm guessing you can give us an alternative practical explanation. Thanks again.

[@GazosKingos]

[@jjkay100]

Thanks Roger: really entertaining video. Could I add something about the energy required to raise the temperature of water. You need 4200J to raise the temperature of one kilogram of water by one degree Celsius. So, a one litre kettle (1kg) filled with water at fifteen degrees needs 85x4200 joules to boil it. That would be 357000J. Bear with me. If, as some people do, you always fill up the kettle when all you need is 360ml for a mug of coffee then you have paid for about three times the energy required. The remaining 2/3 cools and next time you switch on, you have to heat it all up again under the same rules. This is what made immersion heaters in cylinders so inefficient even when the vessel seemed to be well lagged. I wouldn’t want this system now considering the cost of electricity. Another video could go into more detail about the anomalous expansion of water or change of state and latent heat. Maybe about how drinking water needs to be purified physically, biologically and chemically. Just suggestions. You are good in front of a white board. Keep it up!

[@SkillBuilder]

Thanks John I remember all the joules stuff from college but never really used it much. I will look at your suggestions, it is hard to find the comedy in this stuff though.

Roger have you done an in depth video about filling pressurised system in a boiler? I would like to find out what the ideal or most realistic pressure value to expect on the gauge when the boiler is just heating the water cylinder and not any of the CH radiators.

We use an electronic water softener on the incoming water main. It's a little box of tricks with two wires coming out of it, one winds clockwise round the pipe, the other anti-clockwise. We live in a fairly hard water area and have never had any issues. They need an electricity supply for the wall transformer, but other than that are fairly easy to fit and require zero maintenance, chemicals or salt. *EDIT:* Water King is the brand we used: waterking.co.uk

[@1414141x]

Yes, thanks for the recycled piss analogy Roger......I have a question you may have already answered in a video which I have not seen. It's often the case where you need to access the floor voids in a property with chipboard flooring - usually plumbers and electricians may need to cut out for re-wires, pipework and fixing leaks etc. So you cut a chunk (usually a rectangle) out of the chipboard flooring to gain access. Would like to know your method on re-instating the floor afterwards so that you get a good fitting , flush and stable repair to the floor ?

[@SkillBuilder]

I use the big hole saw from Armeg or SuperRod and then drop in a blank plug. It fits perfectly. If you need more then cut the floor out across the joists so you can pop it back.

[@1414141x]

@@SkillBuilder Thanks. I've developed a method which seems to work and does not require big hole saws or blanking plugs.Nor does it require you to put extra support noggins in (in most cases) because the cut out peice of board is now smaller than the hole because of the saw cuts..In the method I use you can use the piece you cut out again and glue it in place ! I'd like to share it with you and get your opinion on it. I can't do videos but I could do a mock up and take some stage by stage pictures with explanations.See what you think about it. I think it's my own idea but probably I saw someone else do it or a video years ago !

I believe in the US you are allowed to let it expand into the cold water line. However in many city water settings we need pressure reducing valves to knock down the pressure. In those cases my understanding is it's a closed system and you want an expansion tank into the hot water tank's cold line.
