Although long - Please Read this hilarious story! 
The other day a close friend told me of a funny diy disaster he had in his new house what he had been living at for just over a year.
My friend moved house just over a year ago, and in the new house there was the typical old fashioned gravity fed central heating system with the typical gravity feed bathroom items. (loo, sink, bath, etc...)
Everything had been working fine in the house since he moved in, although it is worth noting the loo in the down stairs WC was slow to fill up, although not much of an issue as the downstairs loo was rarely used - He presumed it was old and corroded pipes.
Anyway he decided to have his old central heating system upgraded to a new high efficiency sealed high pressure central heating system. Away went the old expansion tank for the gravity fed system, and in went the new Worcester boiler and expansion tank with the system fully working.:
Continuing on, after the new system was installed he noticed very quickly on the evening of having the system completed the boiler and system in general started making weird noises and wasn't working 100% correctly - He just thought the system was settling in.
It now that all the fun started. The system now went drastically wrong when one evening later in the week the boiler cut out giving a low pressure/overheating warning!
After this, he checked the pressure on the system and re-pressurised and bled it!
Sure enough, system worked fine for just under a week, when the same problem happened! - Scratching his head to why the pressure was randomly going down.
At this point he checked for obvious leaks and faulty pressure relief valves - nothing found , so decided to call out Plummer. Plummer comes out, finds nothing but replaces pressure relief valve thinking it may be faulty.
To no avail, this does jack squat.
He is now at this point getting very frustrated and cross, so he decides to inspect every pipe, bend, joint and part of the system.
What does he find.....The down stairs loo is fed of the return side of the central heating loop! , with the pipe work buried in box section what he has never opened and thus never noticed!
It turned out that in the past some dodgy/lazy person decided to cheat and rather than run cold mains water pipe to the loo, to run CH return pipe from a nearby radiator! This was not noticed in the old gravity fed system as, the expansion tank in the loft just filled the system back up.
So in summary, when he had the new sealed system installed, the downstairs loo was draining the central heating system evreytime it was flushed! - What a bodged!
