Hi all, just recently the central heating in our house stopped working. 
It would appear that the pump is acting up, as the boiler (Glowworm 
Ultimate 50BF) still heats the hot water, and the room temperature 
thermostat still 'clicks' when it is turned. The pump, however was red 
hot to the touch. One of my neighbours is a young chap who works for 
British Gas, so he came in to have a look. By this time, I had turned 
the boiler off and the thermostat down, and the pump had cooled down too.
When he came in, he gave the pump a clout with a rubber mallet, and 
turned up the flow rate to max (I couldn't see this, as it was on the 
reverse side of the pump). Lo and behold, the heating started working 
again. However, the other night there was a horrible smell of burning 
electrical components, so I turned everything off.
The pump is a Commander 'S' SMC, and the neighbour reckons it's about 25 
years old. The problem is, apparently the size of the bore. He brought 
around a new pump to replace the old one, but the bore on the old one is 
about 1", whereas the new one is probably metric 12mm or similar.
Question is - is it possible to get either a new pump with the old size 
bore, or could I get reducers to change to the new pump's bore? Needless 
to say, the pump is in an awkward position, and would mean the removal 
of kitchen cupboards to replace it.The old pump has a valve on either 
side, by the way.
Any help, thoughts etc. greatly appreciated!
Regards
John

Hello :o)  Imperial and metric piping can be joined, but an adaptor is 
needed for some sizes, depending on the type of joint and connector used.  I 
know there are Imperial to Metric Compression joint adaptors available, 
3/4" - 15mm  cost should be under a 1.

A local plumbers merchant should be able to help you out :O)
