The problem with draining central heating, especially when its not been drained for a long time is the unknown amount of sludge built up in the pipes and the header tank. There are two ways to isolate the water supply to the central heating.
1. Turn the mains off under the sink stopping the header tank filling.
2. Turn off the supply from the tank usually via a gate valve.
The problem with both these methods is when filling the heating back up any debris/sludge in the tank will enter the central heating blocking pipes and causing problems.
So a wise decision is to go in the loft and check the condition of the water in the header tank. A dirty tank indicates a dirty central heating system and perhaps a power flush would be a good idea.

Draining central heating is not as straight forward as you think. if it's a new combination boiler system draining down is easy and filling is straight forward. Adding chemicals is sometimes a pain but acceptable.
However if it's an open vented, old system lots of problems are waiting for you to discover. The first problem is the gate valve on the cold feed breaks internally, but you won't realise this till you try opening it after the work is complete. Another problem is you think the gate valve is working when the water empty's out of the system, in fact the ball valve is stuck in the closed position and just waiting to fall and flood the house.

Today I went to look at a possible job on The Newark, in Leicester City centre. Parked up and walked along looking for the address, walked past Castle Gardens, past the Newarke Museum and had a good look around at the buildings. Found the Flat but the job turned out to be a problem throughout the building so maintenance contractors had to be called. A none earner but I wasn't dismayed as I enjoyed the walk around the area :-)

I've been a plumber all my working life. I started on the Leicester City Council at the age of 16 in 1982 and did a 4 year apprenticeship. I left the Council in 1995 and set up S A Plumbing & Heating. When I worked on the council there was no Gas Safe or Corgi registration so when I left I had to join Corgi to continue working with gas. I have had experience with every part of a domestic dwelling from the foundations to the roof, working in many types of houses across the Leicestershire area. My main workload is predominately gas work whether it's servicing, testing or installing. Although I do have a vast experience in bathroom installation, tiling and plumbing in general. As you can see I'm writing a blog! Who'd have thought it. I do my own website, therefore I'm a web administrator and now I'm a blogger too. I really enjoy this aspect of my business, it couldn't be more different to the type of work I normaly do.
