Hey Pete, im a plumber from Ontario, Canada 🇨🇦 I dont do much work on boilers and like to watch your videos to learn about them once in a while. Great work 👏 👍
Very neat drain down idea the engineer incorporated into the house, but he should have left the hoses off to provide an air break, the water meter fitter would have pretty quickly realised his fu then.😉👍
Great vid - Working up in Scotland now and nearly all H/W cylinders I work on have a drain off's that are hard plumbed - ie 15mm copper going to an outside wall. Must be a Scottish thing but makes draining down so much easier and I try and do my installs the same way.
17:30 Need to use quarter turn valves on those and not drain cocks for each one of those to completely isolate the lines. I am surprised they put all the plumbing in the attics there. Here in Texas we have no frost line per se. Although we have gotten down to -20C at times, our fix is to let the facuets drip slightly to keep water moving that is warmer, and prevents freezing of the pipes. 🤠👍
@ 6:46 this type of water pressure regulator does not need to freeze to fail ... they are of poor quality in general ... and during the load they do not maintain the regulated pressure on them ... the ones in the D06F series from Honeywell are much more stable - moreover, with any gas or water regulator, the larger the diameter of the internal membrane, the more they can deliver fluids at high flow rates with the pressure regulated on them stable and have minimal pressure drop in case the pressure difference between the inlet and output is small… A good way to choose a quality pressure regulator is to choose the one that has the largest diameter in the area where the membrane inside is located
Drain cock system looks like a setup for somebody who goes on holiday for long periods in winter and is paranoid about freezing pipes and resulting flooding
@ 6:00 I only use HONEYWELL D06F series of PRV - the one with the stranier at the bottom - if the water main has very high pressure, then I use the version with the brass filter housing😊
Hi Pete.. Always a relief when you can stop the water in a stressful situation for a customer, especially when you come across an unusual situation. Ref cylinder - Black rust/corrossion. Are those cylinders steel and glass lined ? If so there is a possibility that the glass lining has cracked creating excessive corrossion to the cylinder itself and possibly causing a structual weakness ? Take care
If it was an old engineer could have linked them together if system air locked. Keep out side drain off shut and mains pressure to blow air out of rads or hot water taps. Seen it before
Just a thought regarding the hose pipe linking the drain points. Would that potentially be against water regs? Surely that would be link a filling loop on a pressured heating system. You'd need a check valve and removable link. Only a thought.
it might be yes, but you’d think the guy fitting the water meter would have picked up on it Also not sure if working in your own home you have to abide by any regs, like you can work on gas in your own home
@@cliveramsbotty6077 as a home owner, you can work on your own gas appliance without being gas safe You only need to be gas safe if you’re being paid to do the work. At least that’s how I understood it, unless something has changed recently?
@@PBPlumber it seems to be a bit of a grey area where imo it should be black and white. RU-vidr Derek from TomKat gas training has an excellent video on what 'you' can and cannot do on gas with quotes and reference to the actual revellent regulations. As most 'information' available seems to say that it's okay as long as you are competent and not being paid for the work. You do not touch the heat producing components (combustion chamber ect) or gas line from meter.
May have been better if the drain pipe to outside did not have a drain tap on it 😟. Yes some of those immersion heaters don't want to come out very easy . 👍👍👍👍👍👍
Yeah all needs to be cut out I’m afraid as no air gap, or double check valve on cold main side. Could be used as a filling loop. The things people do. Looks clever but wras approved?? 😂👍
His contaminated his water with inhibitor and heating water 😂 if he did 2 external draincocks 1 for central heating and 1 for potable then cool. But they're potentially killing themselves.
@@PBPlumber yes very unlikely but mechanical failures do happen and it’s the law to require cat 3 protection (double check valve or air gap) love your videos!
