I know that an RO membrane works better under higher pressures, and warmer water temps. producing its rated GPD means meeting certain temp/pressure/tds guidelines.

Well Im looking to make my RO unit as efficent as possible, to produce as much water as I can possibly get at one time.

my tap water TDS is around 100ppm, so this helps my membrane, my water having low TDS, Im also able to feed it water that is around 80F, which further helps the membrane achieve its rated value.

now the last step in getting the most out of my RO unit is to purchase a booster pump.
My water pressure is already 75 PSI, but I want to boost it to 120PSI to feed my RO filter.

my problem is im unable to find any information on weather or not the housings can handle that sort of pressure, keeping in mind that as the 120PSI water enters the larger filter chambers the pressure will drop a bit.

I will also have pressure gauges mounted to moniter the incoming water pressure, the outgoing water pressure, and the storage tank water pressure.

can the RO filter housings handle the high pressure?

The only sure source of data is user documentation or the manufacturer.

Once you get beyond accepted house pressures, all bets are off unless the manufacturer specifically says a booster pump is okay. Oftentimes they will recommend a particular one for a specific application.

all booster pumps offered by places that sell RO units, seem to be 80 PSI boosters.... which is only a 10 PSI gain.

Im hoping to reduce the amount of water wasted in my system, as much as possible.
