Your fine if your water pressure is about 65psi or more, if not brs has a good booster pump.
Im not exactly sure what my water pressure is but Im assuming its less than 65psi. I live in a condo complex and use to get 1 gallon of RODI water in less than 10mins. There was a huge water main break in another building which affected all the buildings and since doing the repairs my water pressure has been cut by more than half and it now take almost 25 mins to get a gallon of RODI. I have complained multiple times and they said that there is nothing they can do.
Aqua fx. Worked well when i needed one. Just sold one dirt cheap too wish i would have known.

I suggest getting an inline pressure gauge to put on the input water line just before the membrane cause you can also go too high on water pressure too with a booster pump.
A $5 pressure gauge at depot to test you home pressure, to determine what it is would save you the higher cost of a booster.
You might have a clogged line or prv valve ( pressure reducing valve) which is right after your homes main water line shut off.

Definitely get a pressure gauge. If it's right on the border and you toss a booster pump on you could damage your rodi unit.
I had about 35-40psi before adding my 150gpd upgrade. I added the booster pump and it sits right at 65psi. I can pump out 5gallons of water in about 30minutes and fill a brute trash can in a couple hours.

I got mine off ebay about $50 cheaper than hobby related sites. Couldn't be happier considering how low my pressure was in my apt
I would buy the Aquatec 8800 pump and get a good quality inline pressure gauge. The 8800 is adjustable. Got mine from BRS. You can buy the pump components separately if you want as well, but the below URL is a kit. I have the 75 gpd BRS membrane with their water saver second membrane kit for 150 gpd total, and feed the unit at 80-85 PSI from the booster pump. The unit with the booster pump actually makes about 200 gpd in the summer.

Glycerin filled pressure gauge. This is better and longer lasting than the slightly cheaper air filled one they sell.

I also use one of these just as insurance, an inline filter that goes before the booster pump. Cleanable and reusable:

Tony, I have never had the ends pop out of the switch or pump as long as you push them in correctly. But there are retention C clips that I use just in case. They slip into the space you push down on to pull the the tubes out of the fittings. I don't use the ones below, but red ones that are very similar.

Got everything setup and mounted today. I went from 38 psi to 92 with this. Filled a 32g brute in 2-3 hours. Very impressed.
One question -- they say there's a small screw on the pressure switch but I can't seem to move it... Is it that tiny hex thing?
My booster bump has a regulator with the hex screw. It's a deep seated screw and will allow you to adjust the pressure required for the auto shutoff valve to kick on.

Apparently it's the worlds tiniest screw because even my smallest seems to be too big and isn't catching. Im too blind to see at that kind of detail tbh
I did some more research and it seems 90 psi is good and has the best rejection rate. Assuming the plastic canisters can handle it of course...
Mine actually came with the hex tool and your right it is tiny. I might have an extra if you need one.
I have mine set at 65psi which is what was recommended for my pump. I'm sure they are all different.
