Cheers Peter.

I didn't know you you were around thanks for your advice. as you will tell i'm new to the wfp game.

 and alan i can see now that if you have lots of work then yes you would need a larger unit as i have found that you do need to use lots of water to get the windows as clean as trad.

been tight on water for the first week and got spotting on new cleans but my regular cleans with near perfect upvc frames came up great. wasn't prepared fpr the resin giving up after a week though

Allan, all my customers have the option of upgrading to the 300gpd for very little cost, but very few have seen the need.  Quite a few ask about the upgrade when ordering, and I tell them there is no need.  I then tell them should they find that they are not producing enough then the upgrade is still available as and when they need it, I have had only a handful of people upgraded.  Remember that most of these people use a storage tank of some sort.

I know exactly what you mean about speed and good results, but it depends more on how you use the water, as opposed to the volume of water you can go through in a day.  Like I have said in many posts on this forum, I have seen lots of people, wasting lots of water, and lots of time.

I started by setting the variflow at the lowest and scrubbing and rinsing the window but found it would still leave spotting behind so now scrub low then turn up to rinse. but have found also that it is very important to get the frames very clean befor touching the windows.
so on first cleans and 8 - 12 weeklys i use double the amount.

Perhaps I missed it, but did you run the RO for 2 hours, with the flush valve in the normal position, and without the DI? The membranes are coated in chemicals that first need to be removed.

am quite disapointed with mine if i was honest. without a booster pump its produces 12lit per hore : with booster pump am getting around 27 or 30lit per hour.

people on here with the same booster pump get more than me with 450GPD ro's of around 500 liters over 8 hours  were i would get 240 lol.

Maybe it's time to change your prefilters? That can have a detrimental effect on production rate.

I doubt it its only a month old  : and its been like that from day 1

oh haha, hmm, maybe it will get better when the weather gets warmer again.

ive a 200gpd from purefreedom had it about 3months, iam a bit disapointed with mine as well,i dont have a booster pump and i struggle to get 200litres a day!!! plus i have to change resin in di every week!! tds from the tap is 357. i was told a bag of resin would last me 8 months. i dont think so !!!

[[GQC] Tim]

Do you have one of those tiny DI canisters?

Also keep in mind that because of the cold they produce far less pure water.

[mark311069]

yep small di. iam getting 25% pure and 75% waste!!!!. bit worried about the next water bill

hi mark where do you get your resin cartridge from/ windowcleaning warehouse or pure freedom?

How is the waterpressure there?

[mark311069]

ive got the trolly system and 200gpd from purefreedom everything from there

[mark311069]

water pressure is ok not sure how much!!

[[GQC] Tim]

water pressure is ok not sure how much!!

You can't really tell how ok it is until you've installed a pressure gauge. Maybe you need a booster pump.

[Peter Fogwill]

Another thing good about the pressure gauge is it can let you know when the prefilters need changing, if before the 6 months.  When the gauge starts to dip, your prefilter need changed.

[mark311069]

thanks for the info guys, can anyone tell me where i can get these from.? and are they easy to install.

[L.J.Thorpe]

is the pure freedom set up different to ro-man system

am quite disapointed with mine if i was honest. without a booster pump its produces 12lit per hore : with booster pump am getting around 27 or 30lit per hour.

people on here with the same booster pump get more than me with 450GPD ro's of around 500 liters over 8 hours were i would get 240 lol.

that seems low output....for comparison i have 300gpd ro-man,tds in averages 500 + (highest reading i have made is 589 : lowest 469 )comes out of ro at 009 then into di which is just a standard 700ml unit.even during the cold weather i got about 21 ltrs per hour and in the summer nearly 30

[Peter Fogwill]

Yes L.J. They readings seem consistent with what I get from my systems, that is why at first I thought it was a Merlin system, or a rouge membrane.
