No but I can probably cobble one up from an old ro system. The water pressure is definitely low when I live. A fellow window cleaner in the same town has similar issues.

From what I've learnt today the clarke booster pump will solve my problems...its just a case of getting one in time!

I don't think you can deduce that without knowing your water pressure. Mine is low, but I still got about mid 30s before the membranes wore.
