Look carefully at this picture........... its a waste pipe catching a leak, piped to a drain. Stupid idea right? ok, this is why.
Leak is BEFORE the internal stopcock
The water main is being replaced TOMMOROW from the main in the street
The main is LEAD
The outdoor stopcock is 3 FEET down, and snapped off
The client needs water in the morning so i cant pinch it off
So this WAS the best solution!

This is the filter from a single stage Dungs valve running @ 143kw...... the black stuff is sticky and smells like flux......... suprisingly it was choking the valve so much that the internal working pressure (measured from the test point on the valve body), was 8mb at full fire......... unsuprisingly it locked out often!

A new bathroom install was causing a smell for a large client. The entire bathroom was boxed and plastic tiled, so minimal disruption was called for. I inspected the situation carefully and noticed the toilet was internal overflow. Best guess was someone had failed to cap the overflow pipe....As you can see that was it! (its capped temporarily with silicone by me so the original contractor can come back to rectify) note - 'new bathroom' applies only to things that can been seen apparently..........

To my suprise THIS was blocking the supply pipe to a toilet. In fairness it was one of those cheapy 15mm small bore flexi pipes, quite twisted too. I must comment tho, as most plumbers do, I blew down the flexi - diagnosis - 'blocked' then (obviously) sucked on it to clear - diagnosis ..... nearly swallowed the little blighter.

Amazing, this hole is directly under the flue outlet for a Keston Celcius 25. The flue was installed right, so only minimal condensate was escaping, but it corroded right through the leadwork. Ive seen this happen to copper pipe when its used as condensate pipe, but im suprised it managed to do this to lead.

Ok, so what your seeing is an indirect heating coil inserted into the immersion port of a cylinder........ its a form of retro fit........ old school right? NO, they sell these again now to add solar capability to a normal indirect (single coil) cylinder.....
I wonder if we will get 'C/D rated' boilers back one day? I think we will (not while we still use fossil fuels tho), when they realise it costs more in carbon to make 5 boilers that last 5 years each, than 1 that lasts 30 years

A client asked for an approximate water usuage for a 40 room hotel today. Not an easy one to answer. Its all down to the number of guests, type of system and how its used. I have the horrible feeling its going to mean a lot of research for not much gain. Oh well customers always right I suppose!
