Salamander CT 60 1.8 Bar Twin Impeller Positive Bathroom Pump - CT60B

Good pump, not silent but fairly quiet, does the job, easy to fit as it comes with the stainless steel braided flex hoses and connectors for 15mm pipe

This is a great device. We are renovating a seventies time capsule bungalow blessed with long runs of 15 mm pipe. The flow of water to all outlets was dire. Fitting solar hot water, so need a gravity system. This pump is crossover technology, which means it can work one outlet only, such as loo or kitchen hot tap. It runs the whole place and shifted a scary amount of built up gunge from the old pipework, after which it got even better. The supplied hoses are really too short and inflexible. They would make fitting awkward so I replaced them with longer better ones. The only issue is that it is quite noisy. I have it in a basement underneath a concrete floor and it is still audible.

Seems to be a decent all bathroom pump that will tackle most minor demand situations without blowing your head off.
