    I'm just replacing the overflow pipe from our fresh water tank and SWMBO mentioned that it should have a non-return valve on the end of it to stop insects crawling up it.
    Not something I would have thought of. Would this be normal?

    never seen one with a NR valve.. so no, not in my experience

    also doubt whether the small head pressure in the overflow pipe would be enough to open a NR valve

    If SWMBO is worried she could supply a piece of fine mesh that you could fix 'tight' with a cable tie!

    Should be simple enough to make a u-bend so water would be trapped stopping bugs getting in.

    the problem with that idea is the water in the trap would stagnate, a breeding ground for bacteria

    in all my years I have yet to see insects getting into a fresh tank via the overflow.. it's not worth worrying about

    If you are really concerned, fit a carbon filter on the discharge line from the pump..

    or on the cold line under sink , for drinking water only.. plenty of cheap ones around.

    Thanks. I'm not really that concerned. Just paying lip service to SWMBO.

    Good idea that.
    Yes dear I've sorted it dear, no chance of any nasty creatures getting in to our nice clean tank dear, would you like to crawl under on the cold damp ground and check dear?
    No?
    Thought not. :whistle::LOL::LOL::LOL:
