Real life day to day plumbing!

The Landlord just wanted a shower that worked, tidy up as best as I can and put the shower head on the adjacent wall.

Now am I happy with the end result, not particularly! If I had my way we would of been re routing supply cable and pipe so that they were hidden within the shower itself but as I was on a budget sometimes you just need to grin and bear it

Just another boring day of services for me. Started off with this Ariston(not my favourite boiler) but the heat exchanger cleaned up not too bad, bar getting the polish out.

Unless the boiler has a fan pressure test that tells me whether it needs cleaned out or not I always strip it down and clean it as best as I can, namely because;

A cleaner heat exchanger not only gives you cleaner combustion,thus higher efficiency, but at the same time I’d argue it gives your boiler a longer lifespan.

Ok I’ll try my best but this will be a bit of an Elm Street to tidy up

In response to all the comments on my recent post about the two boilers and undersized gas line. this is what an undersized gas line can result in so it is vital that it is done properly!!!

I was at an interesting one today. For context, I was at a property to service two boilers, a 30KW and a 29KW.

I went straight to the meter and noticed they had the outlet in 22mm, to supply 59KW 🤦‍♂️ if both boilers were very close to the meter you’d maybe get away with it.

For engineers out there the photographs are as follows;

1st OP at meter

2nd OP at farther away boiler

3rd OP at farther away boiler with second boiler in operation

Needless to say a call to gas safe was needed as I was panicking I would have to shut them down until gas line had been upgraded. Now, according to gas safe;

The line as it stands, as long as FGA and gas rate at each boiler is ok, is classed as NCS. I thought AR at minimum but I was wrong! Enables me to make the customer aware and book in to come back and upgrade the gas line.

No matter how long you have been in this game there is always more to learn! Thought I’d share this incase any other engineer runs into a similar circumstance.

This is why I always go on about doing gas line calculations properly, it really burns my custard when I see this kind of thing 🤦‍♂️

One of those afternoons, silly wee complications in this line of work do happen. In hindsight I’d imagine the boiler was fitted first as it was not possible to access FGA/flue integrity test points without some butchery to the top panel above 🤦‍♂️

Definitely my funniest birthday present 😂

Em….. is that an order or a request?! Can’t see that washing anywhere that parking is at a premium but if it does work I know what I want for my birthday
