Are you disappointed with the performance of your Reverse Osmosis system?
If it doesnt have a booster pump then fit one now. Check out my other items for booster pumps. Most membranes need at least 50psi to work at their optimum. Read my thoughts on RO systems at
Once you have read this you will understand what an adjustable restrictor can do for your system.
Less restriction means lower pressure = lower pure to waste ratio (bad)but slightly lower tds (good). If you are not bothered about water consumption this can increase the life of your resin slightly.
More restriction means higher pressure = higher pure to waste ratio (good)but slightly raised tds readings (bad). If you are on a meter, harvesting rainwater or your eco tendencies make you want to preserve water this is the option for you.
Fit one of these and it will give you the chance to do a bit of fine tuning to your system.
Please note. Many sellers of booster pumps and RO systems state they are not suitable for continuous running or for window cleaners.
Not strictly true.
