I haven't changed my prefilters or resin in a YEAR

[koopmaster]

As above. My tds is still 001 and I use about 1000 litres a week. My thinking is if my tds is fine then leave it alone.

Yes?

No?

What do you think?

If you've tested the meter on tap water to see it's all in working order, then absolutely fine, mate. Enjoy the blessing [emoji106]

For what they cost i would change the pre filters to be safe

If they are not working efficiently chlorine will gradually start to ruin the membranes

Once that happens you will wish you had spent 20 quid changing them
