Hi All,
I've ordered the parts I think I need to replace the existing pump that has failed. I'm referring to the circulator in the airing cupboard. I have a system that has a CWSC and a F&E tank in the loft - also an indirect hot water cylinder.
I've taken delivery (from www.bes.co.uk) today of:
5M HEAD CIRCULATING PUMP, 230V ac, DAB (product no. 13926)
1½" BRASS PUMP NUT ONLY (X 2) (product no. 9347)
I started the 6129 tech. cert. at the local college in September, so I thought I'd tackle the pump replacement.
I think I've omitted to order something, though I'm not quite sure what. I think it's referred to as a union. Looking in the airing cupboard I can see some sort of flange between the nut and the 22mm pipe. Is that the union?
Is the item I need here:
www.bes.co.uk : (product no. 9344 or 9345)
Pictures here?

I should mention why I haven't bothered with pump isolating valves. Well the existing system is an ancient Glow Worm Space Saver 50 - and the entire lot will be ripped out and replaced after winter. The gate valve above the pump (pump is in a very short run of vertical pipework) has been leaking onto the pump for months. The gate valve, pump, nuts, flanges (unions?) are corroded to hell.
I'm planning on cutting the pipe just before the top of the gate valve and just after the bottom of the flange and remove the entire rotten lot and replace.
I'm using John Reginald Central Heating Fault Finding & Repair as a guide.
Happy Christmas!
