    If you could send me a video of you doing the tests I should be able to help.

    Hi Molly, we’ve sent you an email.

    I see. It’s the top calculation in your initial post. Multiply whatever your turnover is by 1.7. Whatever that number is is what you divide the water volume by.

    Hi Neil,

    The instantaneous bather load calculation is:

    Water depth Maximum bathing load
    < 1.0m 1 bather per 2.2m2 1.0 m to 1.5m 1 bather per 2.7m2 > 1.5m 1 bather per 4.0m2

    The circulation rate calculation is:

    Maximum bathing load x 1.7

    Does that help?

    Hi Dariusz,
    You’re correct in both cases. 10% is clearly going to be much safer than +30% strength and will cause less problems with fuming and corrosion.
    If you’re in a hard water area, calcium hypochlorite will further exacerbate that and lead to on-going maintenance issues. Better to use sodium hypochlorite.
    Hope that helps,
    Adam.

    Hi Jim,
    Just tried that assessment and it’s all working fine from what I can see.

    Do a risk assessment. Doesn’t sound safe to me by the information you’ve given.

    Hi Ben,
    I’ve had a look at the photo you sent and I have to be honest and say I haven’t got a clue what’s going on with it. It certainly doesn’t appear to be a conventional layout.
    Sorry I can’t be more help.

    You can upload the photos straight into this thread.

    I’m assuming the ceiling space is too high to access?

    Hi Ben,
    If you could send some photos I’ll take a look.

    After the pump the pipe continues vertically up the wall before disappearing into the wall near the ceiling.

    Do you know what’s on the other side of the wall?

    Hi Kevin,
    Thanks for your feedback.
    We’ve reviewed this issue and have now introduced a ‘View Questions’ button that you can click after completing the assessment which will tell you which questions you got correct and incorrect.
    This should help you to focus on which areas of the course content you should revise before re-attempting the assessment.

    Hi Matthew,
    No need to test mains water balance – it’s the pool water we’re concerned with. You’re aiming to keep within +/- 0.5 of zero as it relates to the pool water – the mains water is not tested or relevant to the +/- 0.5 tolerance.

    All corrective actions are contained within the course content. Keep the pH optimised for chlorine effectiveness, adjust calcium hardness and/or total alkalinity if they are outside of 80 – 200, keep the TDS as low as you possibly can.
