Filter Guys,

Can you answer a quick question for me?

After replacing my last set of filters, I found that a 5 Gallon jug would take approximately 1 hour and 45 minutes to fill.

Recently it is taking approximately 2 hours and 50 minutes to fill.

I have a 50 GPH system.

Does this indicate that something is wrong or is it normal to take longer and longer between filter changes?

It's been approximately 3 months since my last filter changes (sediment, 2x carbon, and DI Resin) and the water coming out is still perfect 0 PPM.

Any ideas?

I would expect a 50 GPD membrane working at at top performance to take about 2 1/2 hour to make 5 gallons. I guess what your asking is why it was outperforming before and is performing normal now. Membranes can outperform by about 20% which could account for the difference in over performance and your current normal production. High pressure and warmer water (77 degrees) generally provide the over performance.
