Water taking ages to filter

[Tdogg1975]

I have 3 x 20 inch prefilters
Then a booster pump attached to a 4040 housing membrane.
The membrane and filters are 3 months old.
I’ve been working on 70:30 waste ratio (approx)
Takes roughly 2.5 hours to produce 400 ltrs of pure water.
Just recently it’s taking so much longer, at least double to achieve same results.
I’m having to almost close
Waste just to get a trickle of pure.
I’ve no idea what’s happened?
Any ideas please

Your sediment filter is likely clogged and quite possibly your carbon filter is shot as well this will slow down production, sediment can spike at times I check mine at least every 2 days.

You do need to keep a close eye on your sediment filter mine can last weeks or two days, also the carbon filter I estimate my total of water used and get 9 weeks ish out of a 10-inch carbon filter I use 400ltrs of pure a day 4 days a week maybe less but maybe a bit more,

if you aren't that far from the water from the source of your water and the dosing station then high chlorine will kill your carbon filter sooner than the advertised spec, a mate of mine lives just over the road from an underground reservoir which supplies his house his tap water can smell of chlorine at times, I am good distance from the underground reservoir in my town so minimal chlorine in my water

Could also be the water is much colder so it will take longer to produce.
