Bronze pumps

[armb]

The underfloor heating pump that was replaced soon after we moved in should have been a bronze one said the Nu-Heat engineer, because the underfloor hoses don't have an oxygen barrier (unlike modern underfloor heating pipes - this is also why the (steel) radiators can't be on the same circuit). I cleaned a lot of crud out of it last weekend, and the plan is to change the downstairs tubing (that hasn't given any problems yet) next year (or maybe the year after).
I did look on eBay for "bronze pump" under "Plumbing".
eBay found one, and helpfully suggested I might want to look at some others, under "Shoes"....

I suppose I could use stainless steel one - but maybe not.
(I was also wondering if the two pumps could be swapped now the boiler one will be doing more work and the underfloor one will be doing less, but not without quite a lot of reworking the boiler circuit to make room for the larger pump. Maybe I'll put an additional pump in the radiator branch.)
And I thought I'd fixed a longstanding drip in the hot water mixer valve pipework while putting the rear tank back last weekend, but it's still there, though slower, and I'd created another drip while I was about it (which is now fixed, I think.
Still, at least I got the windpig greased last weekend.
