Quietest small condensing pump to use in kitchen?

[Matt723]

Hi All

Found out my condensing pipe had been dripping water right outside my house next to the brickwork years ago .. I am looking to redirect to the kitchen drain however I will inevitably need a pump. I am looking for something as quiet as possible, in your experience what could be a good choice?

Also, is it preferable to add a neutraliser like saniflo on the down condensing pipe to avoid dumping acidic water in the drain (using old victorian mixed soil / rain drains)? If yes any recommendation of device welcome (don't have a lot of room in the cupboard but could fit something small.

Thanks!

The grundfos is as quiet as any I have used, but they only run for a few seconds every hour or so when heating is on. No neutralisers needed
