Hi. I'm looking to buy a fancy timer for my central heating. The one I'm looking at says not suitable for conventional unless fully pumped. How do I tell if its fully pumped? My current timer allows me to switch either heating or hot water on independently, or both together, (at least the correct lights go on, so I assume it works correctly). Does this indicate its fully pumped?

That would indicate that it's fully pumped yes.

What boiler do you have? If you have a hot water cylinder, in the same cupboard is there a pump and either one or 2 valves?

Hi Madrab, thanks for the rply. It's a Baxi boiler (can't see a model number). See attached photo. The black pump on the left is one I installed for the shower.

+1 ....

Do you find your shower pump to be a bit noisy?

It shouldn't really be screwed to the floor.

Hi Terry plumb, thanks for the confirmation. Much appreciated.

Hi Madrab,
It was to replace an older one which was actually noisier than the new one. The instructions said it has to be screwed down. Also, I've seen you can get insulated mats to screw them onto I order to reduce the noise. I might try one, but like I said, it's not as bad as the old one. I guess if it wasnt to replace an old noisier one, then I might find it noisy, as I told they are all fairly noisy.

Of course, I've looked but I can't find them now. Do you know why you shouldn't screw it down?

Maybe, but it isn't very very heavy, so I was concerned about it wobbling about and knocking on the floor. Perhaps I imagined the bit where it said to screw it down.... Or misread the bit where it said do NOT screw it down as DO screw it down.... Bloody amateurs

I know that I have the same instructions for a macerator we have in our downstairs loo - it came with adhesive rubber pads that were to be used if it was free standing.

:LOL: ..... ;) ..... (y)

Main reason for not screwing it down -

Noise - screwing the pump down transfers the pump vibrations into the floor, that then resonates (like the body of an acoustic guitar) amplifying the sound, especially if the floor is hollow. Hence the reason for the rubber feet, they insulate it somewhat from the floor and why you get rubber sound absorption mats.
