3 stage mains powered RO - worth it?

[Slev]

Ordered the compact OS system (and a spare set of filters)

Thanks for the help folks.

And anyone in the North tipp area  will be welcome to borrow it.

Any idea what pump would work with this system?

From what I can see @Darren996 this pump should be more than enough

I third that idea

A great idea!

North County has 4, the first 2 were snaffled by the importers (Nigel and James) so now the club only has 2! !

Down here in the Deep South, we get our RO straight from the River Lee! 
Even though Lee water is very low in minerals, I was thinking about RO to provide a consistent base, and that it may end up cheaper than doing several water analyses as the river changes during the seasons.
This particular RO system seems very good value. How are the North County users getting on with it?

Received the ro unit, and hooked it up to the outside tap this evening.  Did the flush/rinse then ran it and got the following :
60 minute run time
2.6l of treated water collected
10.5l of run-off water to drain
Pressure at the tap was 36psi (2.48bar)
TDS of untreated water 422
TDS of treated water 21 (but wasn't careful about the bucket been clean)

Just to note,  that this was its first run.  Water was taken from before a water softener, ie it is quite hard.  It's the 50gpd model.

(just as a rough guide,  it took 42secs to fill 10l form the tap,  which is fed from 1/2inch piping,  which for me is a pretty strong flow rate)

[Slev]

Just for information :
Left the ro system running over night.  Filled 30l in 12 hours.  TDS reading of 18ppm. Pressure at the tap seemed very similar to previous ie approx 2.4bar (didn't measure it this time,  but took about same time to fill 10 l)

Thanks for the info Slev, are you going to have this running permanently or just hook it up as required? Is it a big job installing? Is there a water pressure gauge in the unit?

[Slev]

Only when needed.  It's very handy to connect to the outdoor tap. Just screw on.  And it is small, so easy to put away. I just left it on the ground when in use.   The drain,  outlet,  and connecting hoses are approx 2 m.  No gauge with it.   

Will  upload a pic later

[Slev]

Hoses are 3 metres actually

[darren996]

Handy out, thanks

Just an update.  Got a booster pump from ali which results in 10litres per hour.
