Hi there

there is a few place that do booster pumps,

pure freedom do this one http://www.purefreedom.co.uk/aquatecbooster.html
The guy from red diving from ebay does these http://www.johnhewitt.com/pumps.htm ( you have to work out if your system is in series or parallel)

Do remember that in the cold, the RO system makes less water, the best temp is about 25 and a pressure of about 50-60 psi.

I found it increased the tds to 0 and delivered more water and much less waste.
Do not even look at the pumps a gale force marine on E Bay.Your Psi should be 55 to 80 psi..They say the diferance detween a filter and a membrane is this pressure.The membrene works best under pressure.

You asked a question about water production before. I am convinced by this post, that you didn't follow the advice you were given (by me).

Your ro unit is in flush mode. Turn it to production.
Forget where is says flush or production on the flush valve. Check manually. And know for sure.

Unplug the pipe to your DI unit and watch the water dribble out as you turn it around. Stop turning the valve when water is dribbling out fastest
Even without the booster pump your production should be double this. 

Good move on getting booster pump though. This will allow you to get between 40 to 50 litres per hour.
But only when the valve is set in the right place.
