Is it essential to change the water filter?

We have a plumbed-in water filter at work, but the person responsible
for changing the cartridge says he's stopped bothering because the
water continues to flow. He argues that, if the filter were failing
to work properly, the flow would diminish or cease. For my part I
think the water has stopped tasting very nice.

It's a Bayhall Filtamate if that helps.

Thanks

Edward

depends what sort of filter it is (i.e. what it's supposed to be
filtering)

if just a sediment filter - it wouldn't bother me if it weren't
changed too often - as it will filter out more the more bunged up it
gets..

if "activated charcoal" filter or similar (for taste purposes removing
chlorine for e.g) then it may start tasting less good the longer the
filter is in place (as the filter is "used up")

You need to switch it off or cap it off if it's not being maintained
anymore, so it can't be used. The bactericide (normally silver for
drinking water) has a limited life. The filter slowly builds up
materials to support bacteria growth during use, and relies on the
bactericide to keep it safe.

The person responsible for changing the cartridge has been given a
H&S related responsibility for which he isn't competent, which is
a management failure.

It doesn't, as I can't quickly find what the filter claims to do,
although it probably wouldn't make any difference if I could.

Agreed.

I have also seen the suggestion that once 'full', the filter can release
some of what it has filtered out periodically. No idea of the truth of
this...

They are only £6.75 from the first place I looked FFS!

That is about the price of just one 19L bottle of water for a cooler!

As Andrew said, I would not use it, plus send a formal email to his manager,
explaining the situation, and the small cost of the new filters.

I think the whole unit needs to be cleaned out every so often too, if it is
also a cooler that has a storage tank inside.

We have water coolers in our ofices with a bottle on the top, and they are
fully sanitised every three months, but these are coolers that store water,
if yours is just a filter tap, not a cooler, then I don't think you need to
do this.

There are water test kits you can get for fish tanks that test the nitrate
level - might be worth testing the water from the old filter with that, and
then do the same with water that has not been "filtered" (but make sure you
test a mains water supply (at the same site), not water from a tank!)

The woman who was supposed to get air conditioning maintained but
didn't bother because it still worked got prosecuted for causing
seven deaths by legionaires disease a while ago...

Only if you have goldfish crapping in the pipes.

(Or you're in East Anglia)


I've worked in many offices with plumbed filters. Don't think I've
ever seen one changed
