Interesting is that Rob. Where I live, the water tds is 70 - ish, which isn't much compared to some. However, it seems that the tds doesn't pose a problem with the filter but, the sediment density of the water!
I tried both types of Fibradine filters and had the same problem with both.
Gardiners were excellent in helping sorting the problem out by the way. No complaints there. The bottom line was, they are just not suitable for my water.

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.

Thanks Alex, could you tell me what the lpm would be with the CFB-plus, based on the figures I have given you. Would I be right in saying the CFB-plus filters wouldn't have been available when I purchased my filter in May?

The flow rates of the CFB-Plus are higher, and you should expect to see a drop of only 5-10% from maximum. These were not available through us at the time you bought this one.

I have sent your case details on to the manufacturers representative in this country. They are sending out a replacement filter for you to try out in your system so that you can report back any changes that this may make.

Hi Alex, just to let you know I have been away on holiday, I have got the replacement filters and will do the tests you suggested and get back to you with the results asap (prob the first rainy day which up here won't be far away) or next weekend
