Hi all my merlin unit slowed right down last week (all night to produce about 400l) so took apart to clean through.

Sounds like it needs a complete new set of ro filters plus the carbon one.

I find when mine slows down, that's what's needed.

If the pure water TDS hasn't risen then I'd be looking at the pee filter

Just check that your booster pump is still working as it should (if using one) or that the mains pressure hasn't been reduced -  this maybe because of a burst main somewhere or pipes being replaced
