RO Unit Low PSI
I recently purchased the vertex puratek ro unit. Ive found out unfortunately I only have 21psi of incoming water pressure. Ive read water quality can go down and the amount of waster water can sky rocket. Until i get a booster pump will running the unit at 21psi damage or ruin any of the filters?

Does the vertex ro not have a booster pump?

What's your water source, city or well? If city, check your plumbing for a pressure reducing valve. Should be just downstream of the main water shutoff for your house. It might be adjustable to get you a higher pressure.
Not sure about running your unit at such a low pressure. Probably no damage, but your output will be agonizingly slow and probably somewhat inefficient. 21 psi is pretty pathetic for pressure if it's from the city.

Yeah im going to have to look for that mike. Its actually in a group of newly developed townhouses running on city water. Im not sure i have access to a pressure regulator, all i could find so far was a main water shutoff in the garage, thats it.

Hmm, townhouse, yeah, the PRV might be in someone elses unit depending on how the housing blocks are set up. I was in a 3 unit townhouse in Ottawa for 13 years and there was no individual metering, so the water rates were included in the strata fees. Most of the blocks had 5 units. I reckon I was subsidizing the larger families & anal car washers that were using a lot more water than I. But I digress, if you haven't identified a PRV not far downstream from the shut off valve you found, a booster pump might be your only option in the end. Unless you can get the complex manager/maintainer to crank up the pressure. There's more than likely a regulator somewhere.
