Hello All
I have just started back window cleaning, after a 10 year break, and got myself hooked up with an entry level R/O set up, from The Cleaning Warehouse (Wolverhampton). I have very few customers, as of right now, so, I dipped my toe in the water; as opposed to diving straight in.  Good pricing and decent service , but serious reservations about the 300GPD (Big Fat ?) R/O System!
The reading on the water in pressure gauge seems to fluctuate between 50 and 70 PSI - does not sound that shabby to me. However, the rate of purification is terrible.
Do I need a Water Pressure Booster, or is the equipment incapable of it's claimed 300GPD output?
Thank you for your help
From Steven

Go  back to your old job  mate  this business is flooded with   window washers

I think you probably have the same one as me. I purchased it to replace my tired old pure freedom one. I liked the simplicity of it compared to the 3x100 gal/day design. However, I got nowhere near the claimed 300/day output. It seems to produce only about half of the output of my old one. Part of the problem is that my mains water pressure is not too brilliant (40-50 psi). I have now fitted a booster pump and  permeate pump. It does seem to produce less waste litre for litre and now just about keeps up with my demands. I Don't understand why, but this setup also makes the RO produce a much lower TDS reading (4-8) and therefore my resin lasts much longer.

I think you need a booster your pressure should be 100 psi and a good flow rate to get the best out of it.

The 300gpd is US gallons - its also at optimum pressure (about 100psi) and temperature (about 22c).

In real word situations you should expect 2/3rds the rated output at best.

That said - 200gpd should be enough to keep most one man bands going if its left running 24/7 in a static setup.

Thank you    for your replies
Can any of you recommend a good water pressure booster?

Also to add to Nat's post; its a 24 hour day.
