Common mistake or Common problem? Day In The Life Of A Plumber
Вставка
- Опубліковано 23 чер 2024
- Day in the life of a plumber and we are back to the large renovation we are doing and another common problem we find on the new Worcester 8000 boilers...they suck the life out of the gas meters giving low working pressure but is this a common mistake or a common problem when it comes to these boilers?
Either way the low working pressure needs correcting so we need to update the gas pipe from 22mm to 28mm...which involved going under the floor boards and into the crawl space under neath the house which is never a nice job.
See how we got on re running the gas which wasn't without its problems..even before we started laying pipe!
Thank you all again for your continued support

Anyone had similar experience when fitting worcesters? Let me know, as always thanks for your support 👊
ALLLLL THE TIME. Every 4000 / 8000 has to have 28mm. The compacts are fine with gas norrmally. Also fist thing id do is remove the lead and see if that helps with the gas
Luke love the vid mate. Nice to know we all get the same jobs 😂😂😂 ( Make a site bog, standard bucket with some insulation around the top, a bit of cardboard for a lid, half fill with water) 👍👍😂😂😂
Yes mate, can’t forget the insulation, makes the toilet lot better…bag as well 😅😅
Great honest video, I’ve Faced this challenge many times also , used to gamble, found myself upgrading more than anticipated at times and its put a dent in the schedule. Moving forward from here unless I’m sure I’ll do a Calc and size it. Ten minutes work will give a good idea what’s required and save you over killing it with 28mm as sometimes happens with just estimating the run. Keep up the good work
Thanks mate much appreciated 🙌👍
Easiest way on that gas run would of been Gastite flexible stainless plastic coated pipework and fittings they sell a 28mm upgrade pack online no joins under that floor 😉👍
Never used it, what’s the costing like?
@@bluebulldog_ukIt is quite expensive. 28mm x 15 metre kit is around £300 or so from BES. They’re not the cheapest but gives you some idea.
Some installers don't check pipe sizing or read Mis when installing a new boiler they think the old boiler worked so it will be ok and wouldnt have a clue how to do a pipe size calculation anyway. Good honest video Luke
Thanks 👍
You have to do pipe sizing in your ACS so that’s not true
@@Brizzle9293 you do thats true but how much of the ACS do people remember or go back to…should be done but can be overlooked or ignored or sometimes not been able to gauge where the pipe runs can be a pain
That’s true not slating what you’ve done, more the comment of most lads wouldn’t have a clue how to pipe size. Hear it all the time and it’s pretty tedious, so quick to slate other engineers
@@Brizzle9293 I know what you mean mate 👍👍
Think manufactures instructions say if its a 40kw it can be 15.5 at the gas valve
Ahh you say it in the video
Great video. Big spiders and all!
Thanks mate 👍👍
Well done with that mate, especially on your own, I would have been cursing as well.
Thanks mate….empty house but in back of my head I kept thinking what if someone starts putting the boards back down while I’m under here 😅😅
Should've stuck 35 down the hole! 😂 Even though I think you're still a little low according to BS (1mb drop between meter and appliance) most real world installers know that boiler is going to work just fine. Boiler is only going to run at max during hw demand and will probably throttle down as well. Ch is somewhere round 24kw. Problem may occur if other appliances are fitted, but that's not your problem.
You need an apprentice that looks like a perfect job for one under there 😂 and he’s not allowed up until it’s done!
That was me 18 years ago…throw the apprentice under for the day 😂
I thought i saw a toilet under the floor 😮😂😂
@@mickobyobrien2650 😂😂👍
Got told by worcester on their 162 commercial boilers they will work safely down to something like 2mb gas pressure (obviously wouldn't get the full output though), not sure if that the same with there domestic range, also think their domestic range used to let you have 16.5mbar on the ilet due to the loss through the gas vale and gas connection firtings to the boiler
Just got to 24nmin and You've pulled the page up in the book I was on about😂
😂 yeah I’m sure they will test them right down to lower than what’s in book, commercial I’ve heard there’s more tolerance in the readings
An equivalent Ideal you wouldn't have had a problem with the gas pressure mate.
Yeah ideal am a lot more tolerance and don’t seem to suck the life out the meter 😂👍👍
🤘😎🤘
🙌👍 thanks for the support as always mate much appreciated
.010m3 or IVx1.5
Just remember to put your handbrake on.😀
I’ve never forgotten after that day 😂😂👍
Hi Luke
I'm not being a knob but have you considered the Gas supply being in voids as it's something I really find a difficult scenario.
I'm guessing the ground floor void vented through air bricks but not so sure under the bathroom floor.
I'm sure you're aware but the lead flex on the existing supply is basically 15mm bore and would have been half the issue if not more.
I replace them immediately if I see them
Hi Luke
How's the Installer Show been
Are you there tomorrow

Mark
Hi Luke
I'm a knob after all.
Nothing wrong with Gas pipe under joists flooring.
I've spoken to Gas Safe Register on their stand at Installer Show.
There's a Technical Bulletin on it according to GSR.
Basically test been done and gas will escape
Please accept my apologies.
I've seen your van at show but not you.

Hi Mark, sorry I missed you at installer mate, been a busy few days and not had chance to catch up. Always appreciate people asking questions mate no matter what it is as someone may be thinking the same thing and not know, so it’s always helpful, appreciate the comments and hopefully I can catch you on the next one 👍👍
@@bluebulldog_uk Hi Luke
I ambushed you by your van in the car park
It was great to meet you 😁
Enjoy your content
Have you thought of purchasing a GoPro as would be easier for you to film stuff
I spoke to two Gas Safe Register employees at their stand.
There's a Technical Bulletin about it.
Basically tests were done in relation to under flooring and tiles etc and gas still escaped
Worth knowing
He did though say you should risk assess it for yourself and if necessary fit ventilation
I've done it by fitting ventilation in soil pipe vent boxing etc
Can you put a test nipple on pipework just under boiler,then your first reading may of been ok?
That would be working pressure before boiler, Worcester would have still checked the boiler pressure and deemed it inadequate
@@bluebulldog_uk yeah,thats what it says in the mi
Before the gas vale - 2.5mb then minus on the gas valve itself
Transco are happy with 16mb at inlet gas valve in service mode on max
U should fit a 25kw and save u and the customer lots of hassles
Water pressure too good for a 24kw 👍
Its not a Worcester thing? If you fit a 30kw boiler or whatever size you have to size the pipe to the boiler output?
Yeah you do but it just seems Worcesters am excessive for sucking the gas
Have to employ a small child mate. At a bag of sweets a day it’s a no brainer
Just get central Heatking in for day, works for bag of quavers and a can of coke 👍👍👌😂😂
@@bluebulldog_uk 🤣😂🤣
Why you don't follow industry standards when determining pipe sizing and gas rating is beyond me!
Proper surveying equals a professional instal.
Pretty sure I explain this in the video if you watch it mate about sizing the pipework
@@bluebulldog_uk My point was you should have had a greater expectancy of the possible shortcomings of the installation pipework simply by walking the job and noting just the obvious straight lengths.
It's not just a Worcester issue, all zero governors suffer big losses across the valve.
The Gas rate will always be the ultimate determining factor!
@@johnward5006 pretty sure I had expectations When I explained to customer that it might need upgrading in quote..again said this in video, old boiler gas rate was fine and working pressure.
so the pipe which run vertically was clipped to the door frame is this ok?
I'm looking to do a new gas run in-between floors on a property I'm working in. The builder is trying to make as little mess as possible. (keep the cost down)
normally I would be run behind plaster board or chase it within the wall.. however this time they have requested to run in between floors clipped to the wall. (in the corner)
reading through volume 2 of the viper book I can't seem to find anything which says its against the rules as long as its sleeved both ends. equally I can't seem to find anything to confirm its ok !
How rude 😂
😂😂😂👍👍
Sod this , this is ehy a press gun exsists
I need a press gun now 😅👍
It's basic pipe sizing mate, nothing to do with Worcesters and I can't understand this worcesters suck the life out the gas? 30kw boiler will suck same amount of gas irrelevant of manufacturer. The 1.5mb drop between boiler and gas valve is the allowance worcester give through internal gas pipework. I.e a total of 2.5 mb drop from meter.
Just going off what I’ve seen and other engineers to be honest, I agree a 30kw boiler is 30kw but just seems the new Worcester drops in pressure more than other boilers
Glad I'm not the only one that understands this and quite simply, if an appliance is designed to consume 30kw/hr or 300kw/hr that's exactly what you are ultimately looking to achieve.
2.5 m bar drop allowed through gas valve. 1 mb at test point at boiler.
@@mikewebber5171 1.5 across valve, not 2.5.
I wouldnt be going below a floor with shorts on mate. Feck your knees
I bought some slip on knee pads I normally keep in van that cover most my bottom leg but left them at home 😅
