I have just fitted the fibredyne CFBC filter to my pure freedom van mount. I use a booster pump and before I swapped to a single filter it used to run at 100 psi, now it struggles at about 60 psi. Are these fibredyne filters not compatible with booster pumps?

not noticed any difference on mine

ks, I thought you were in fife? why you using RO or don't I get what you are talking about

Is it the CFBC or the CFB-Plus filter you have?

How old is the filter?

I am Stu, a decided to go with the RO system when a got ma van mount, filters and resin last for ages wi the water up here.

Just put it in yesterday Alex, a bought it end of May. According to my invoice the code is FILTER-PLUS 20, description Fibredyne CFBC sediment/carbon pre filter

yes I know, but with such low tds why bother with the extra hassle, just do di only, just my thoughts, each to their own

When a got ma system 2 n a half years ago a never done much research into what exactly a needed, a took the advice of pure freedom and in doin so maybe they decided on sellin me a system wi the biggest mark up

[ben M]

what is your tds?

[KS Cleaning]

what is your tds?

102

[stuart mc]

what is your tds?

102

really that is high stirling is like 26, mine is about 45, you are not that far away

Aye, it's a wee bit higher than a wis expectin it to be, maybe ma meters on the blink. a find it hard to get an accurate reading on running water but in still water it's 102..... On a side note do you know anythin about Falkirk juniors, we play them in 3 weeks time

I tried a Fibredyne, Just  binned it & now sticking to the cheap 5 micron white filters, changing weekly or sooner if required.

Your filter is starting to clog! which will eventually result in zero feed to the r/o as I found out recently. When investigating, we removed to feed to the membrane and almost completely black water was visible! I don't believe me produced more than 15k from it.

When purchasing the new membrane, i was chatting about the filter to the company i bought from, they did believe the stated figures and warned to be cautious, guess they knew something.

I'm now running at great production rates of 1000lt - 6/8 hrs.

Can I ask you how long the Fibredyne filter had been in when it started producing black water? 
And was you using the CFBC FILTER or the CFB-PLUS FILTER?

Just put it in yesterday Alex, a bought it end of May. According to my invoice the code is FILTER-PLUS 20, description Fibredyne CFBC sediment/carbon pre filter

Did you buy it from us? Does not seem to be our product code. If it has the black ends then it is the CFBC which does have a more restrictive flow rate than the CFB-Plus (blue ends).

However if it is reducing the input pressure by 40psi then this does not sounds right. What is the comparative through flow rates (lpm) with this filter and your other filters?

Yes I bought it 22nd May Invoice No 672, I will take it back out later and have a look at the colour of the ends. I don't understand the last question Alex

I would need to know the change in flow rates through the pre-filters with the CFBC fitted and the standard filters fitted.

For example your water flow rate through the standard pre-filters (not through the RO) may be 6 lpm. What is the flow rate with both CFBC fitted instead?

To measure connect the pre-filter housing to the tap and disconnect from the RO and let the water flow go into a measuring jug. Time how long each takes to fill the jug to 2 litres.

This would give me an idea of what is the problem.

Ah I get it now, I will do that this evening and get back to you.

Hi Alex, the filter has the black ends so must be the CFBC one. I done the test you suggested and it took 14 seconds to fill 2 litres with the fibredyde filter and 11 seconds with the standard filters. You asked the question " what is the flow rate with 'BOTH' CFBC filters fitted" I only have one,  isn't it recommended to use only one of these filters?

Thank you for this. This works out at 8.5 lpm with the CFBC and 10.9lpm for the standard set-up.

I will have to check the specification charts and see if this drop is within the standard parameters.

When I said both I meant comparing both the standard and the Fibredyne - You are correct only one is needed.
