Hi, i would be grateful for any comments. I live in a bungalow with a recently fitted condensing boiler in what used to be the airing cupboard, central so not on an outside wall. It wasn't a problem with the old combi, but with the new condensing boiler utilising the old copper blow off pipe running under wooden floors to the outside and still the need for compensate drain...a pump was fitted pumping vertical to loft space and across to the soil stack as a solution. The pump is screwed to the wall which joins the kitchen, all the internal walls in our bungalow are the stuff you can knock a hole down the middle of, which is great to drop a cable down but that's about it lol. So there is an airing cupboards double doors...about 10ft of hallway and a bedroom door between us and that alarm clock. The pump is an instinct(book says sauermann) 45dba @ 1mtr, my question is...it is screwed directly to the wall, would an anti vibration pad make a lot of difference fitted between the wall and the pump or is it just down to the noise of the pump. Please let me know if you've improved things on a similar situation, I didn't think it would be advisable to fully enclose it even though its a short run period when it kicks in. Thanks very much in advance for any suggestions, Neil
