Well explained Derek. You're right it's a dying art, most jobs on these are just maintenance nowadays. Cylinders are making a comeback but all sealed systems now.

Well done Derek, lost count of the amount of Galvanised steel tanks I installed drilling the fitting holes with a brace and a tank cutter, then mauling them into position and piping them up 😄😄

Great video, on a lot of early 2000s newbuilds we had to fit a combined vent and feed pipe on f & e systems, i never thought it was as good but it was what the spec allowed

Yep remembered that one - cold feed teed into the vent at the side of the cistern....usually off a 'Aerjec'.

The chances of a vented cylinder coil springing a leak are extremely rare, i have only known of one in 55 years of plumbing, they are made of copper after all, good video mind

My understanding is that you can fit a valve on the out let provided the appliance has thermal cut out? Is this not the case?

Hi Derek very good, think you should do a follow up video, showing vent and feed pipe connections into central heating system, I always like the airater (4 pipe connection), still prefer open vent to a sealed system , heat only boiler are so much more reliable, the amount of call outs for low pressure is stupid 😢, also thermostat with battery!!, and smart thermostat, talk about going backwards!, keep it simple , as away great video,

Hi Derek just a quick rant, when I started out there were no national repair company’s, you fitted a system with a old style heat only boiler that just worked( still have boilers I look after 30years old!, only had to change ,could not get replacement flue) in that time your probably go through 3 combe!, do loads of call outs for national repair company and I really question are most boiler fit for purposes , even the so call top brands are not that great, nearly every call out is a combe, pressure or over complicated control, think I better retire 🤣🤣🤣, ends up most customer have a service plan they really can’t afford or never us to have, we have gone backwards

Can’t understand why you would ever want to fit an f and e in. Total waste of time so simple to instal but they can pump over draw in air and get really really sludged ….and I see loads of fitters who don’t understand the set up anyway. Basic plumbing.

@@tomkatgastraining because it makes cleaning a blocked cold feed easy by providing a compression join close to the point of blockage. Because it makes locking up easy with a 22mm speedfit stop end. Generally it just makes all the work needed more simple. Most of these systems have Mark and dirt in the expansion tank this needs to be cleared before we drained down so it doesn't end to the heating system. With an isolation valve we don't need to drain the tank or move the Mac into the system. Although some of it gets stirred up and moved into the system when we refill. In the 1990s I was doing callouts for Watford Council. We had 30 mins to fix any breakdown. An isolation valve in the cold feed make this very possible. So I think many reasons to fit an isolation valve in the cold feed when the boiler has an overheat stat. However your comments about the lack of skills in our industry are exactly correct and to encourage unskilled engineers not to fit these valves in case the boiler has no overheat stat. Properties with this type of system often still have old and out of date appliances. If we say safety first then this could be seen as poor practice. We really need some tighter controls on the quality and training what engineers in our industry. The work that you do here on KZitem is fantastic and contributes greatly towards engineers knowledge. I like to think that I contribute to this also with my own KZitem channel but there's such a big hole the review KZitemrs can't fill.

@@tomkatgastraining thank you for the super quick reply. I'll be working on a f and e system today. All the hot water taps have severely restricted flow due to a blockage somewhere. I'll be cleaning out the tank and maybe I will need to cut out and replace some pipework on the hot water supply from the cylinder. Any tips please about how to drain and or clean the tank and cylinder and pipework? What checks do i need to do to trace the blockage/s? And anything i need ti look out for before cleaning and cutting pipework?
