Outlet Dangers


The outlets of a swimming/spa pool can be extremely hazardous!

As well as leaving the pool via the surface water draw-off system, water is also leaving via the sumps (drains). In a traditional swimming pool, these outlets are usually located on the floor of the deep end and are covered with a square grill.

The video below provides a brief explanation of some of the hazards associated with pool outlets

  1. Hi, I have just watched the video relating to pool drains. I understand the issues around the drains and entrapment but the video relates to USA law. What about the UK, what is the UK law on the use of anti entrapment drain covers?

    • Hi Louise,

      There is no specific law that covers the drain covers, however, the Health and Safety at Work Act 1974 section 3 (It shall be the duty of every employer to conduct his undertaking in such a way as to ensure, so far as is reasonably practicable, that persons not in his employment who may be affected thereby are not thereby exposed to risks to their health or safety.)
      and the Management of Health and Safety at Work Regulations 1999, regulation 3 Every employer shall make a suitable and sufficient assessment of (a)the risks to the health and safety of his employees to which they are exposed whilst they are at work; and
      (b)the risks to the health and safety of persons not in his employment arising out of or in connection with the conduct by him of his undertaking.

      Those 2 regulations cover it really.

  2. struggling with the knowledge test. keep getting 7/8 questions and i think its the arrangement of pool plant components. i believe its the following order: 1. skimmer baskets 2. pumps 3.filters. 4. heat exchanger 5. coagulant injections. can you review the results and guide me please

  3. I have taken knowledge test 4 over 15 times. Every time I get 7/8 questions correct. The only question I could be getting wrong is the one that requires plant room components be placed in the correct order including sample line out and sample line return. I am very confused as I have followed all diagrams of these components based on the diagrams included in this section and it still appears to be wrong. Is it possible that the diagrams are labeled or placed incorrectly? I have tried reordering these components in everyway possible according to the diagrams you have provided.

    • Hi Phil,
      Try putting the sample line return as the first component. Sometimes the sample line return doesn’t actually ‘return’ but is positioned such that sample line water goes to waste. However, for the purposes of this course, you are to assume that the sample line does return to the main system pipework. In this case, the sample line would typically return to the suction side of the system (not the delivery side).
