disconnected
In topology and related branches of mathematics, a totally disconnected space is a topological space that is maximally disconnected, in the sense that it has no non-trivial connected subsets. In every topological space, the singletons (and, when it is considered connected, the empty set) are connected; in a totally disconnected space, these are the only connected proper subsets.
An important example of a totally disconnected space is the Cantor set. Another example, playing a key role in algebraic number theory, is the field Qp of p-adic numbers.
Hi all,
I am a plumber but I do not carry out works to boilers as the majority of my is bathrooms so I am not gas safe.
I have completed a bathroom for a regular customer. She is of old age and is starting to get a little clumsy and her son has asked me to look at the old gas fire/back...

Dear all,
We were disconnected by our gas supplier. We have no managed to find the money to clear the bill. They have told us it will take 10 days to reconnect us.
There is a vulnerable old person in the house and we have no heating or hot water. Also we are worried that the pipes will freeze...
Hi All
What 15mm cap end do i need to cap off this service inlet, plus is there any way to replace it with an isolator type even though there is no height.............
Thanks
Hi, I recently had a new kitchen fitted and it appears that the old cold water inlet valves (one pipe with 2 blue T valves connectors for old d/w and w/m) have been left in situ without being capped off.
I’m very worried that they’ll leak, especially as they don’t have a cap on them. Problem...
Hi, I hope someone can help.
Today, foolishly, I took the spout part of my 3 way Brita filter tap off - the bit that sits just above the taps. The spout was not swivelling cleanly. However what I didn't realise is that the flexible hose that comes from the filter goes all the way up the spout...
Bought a 60 year old house which had a fire backboiler and an oil fired heating system.
When I turned the oil on, the back boiler heated up and downstairs rads where only luke warm.
I never intend to light the fire so I disconnected the back boiler.
System got power flushed and a new pump...

I want to change a kitchen tap so have turned off the main stopcock & hot water supply in the airing cupboard but when I disconnect the flexible pipes water continues to trickle out of both copper pipes. I've waited a few minutes to see if it will stop but it carries on so I'm stuck and can't...
I've got an old cooker from 1930s (see attached photo) and I'm looking for someone who could help to fix a minor leak on it. I don't need the gas engineer to certify it is gas safe, someone else that my housing association employ will do it. I just need someone who can repair and maintain it for...
I'm in the process of sorting out a CH system in my sister's house. She moved in recently and I'm going to move some radiators for her. To my horror I've found the expansion pipe has been cut just above where it was connected to the system and what appears to be an automatic air vent added in...
Evening all. Had a bit of a head scratcher today. called out to a job and the boiler and pump were running when the programmer was off. It was a satchwell/sunvic wiring center, the one with the circuit board in the metal box. I disconnected the wires at the programmer, room stat and cylinder...
Hi
This is going to sound like a really stupid question, but here goes!
When my dishwasher is DISconnected from the pipe, and I turn the little tap on at the pipe, is it normal that no water comes out? i.e. Does water only flow out if there is a machine there to pump it out?
The reason I ask...
