Do I need to put a trap on this washing machine set up?

    Good morning all,

    I have this temporary set up for my washing machine waste. The hose is secured to the waste pipe which exits through the outside wall, under the floorboards, where it terminates above a drain - the upper pipe. The other pipe work seen is from roof gutters.

    The question is, do I need to put a washing machine stand pipe trap in to replace the sealed in set up that’s in place now?

    Thanks in advance for your advice.

    It would be advisable. It would prevent smells from the drain getting into the washing machine and provide an air break to prevent the drain from syphoning out water from the washing machine

    Thanks for the reply. The end of the waste pipe is above the drain and not connected into it. Does this provide an air break and would this prevent water being siphoned from the machine?

    Thanks in advance.

    It provides an air break. To prevent syphoning the air break has to be above the water level in the washing machine

    This is what you need Washing Machine standpipe
    It looks like the waste water is running into the Rainwater drainage, Water Companies tend not to like that ,

    That's true, they can summons you if it is a rainwater gulley - next door received a summons for doing it, but its not certain that one is a rain water gulley. I have one just like it for my utility room, into which the washer, dish washer and sink all drain, but it is definitely a foul gulley.

    I wish people would be certain of their facts before commenting. Firstly, no the current setup is not correct, the hose needs to hook into a standpipe, which will firstly seal off any odours from the gulley, and secondly provide the required air break at the end of the hose that appliance manufacturers require.

    Secondly, without knowing the age of the property, or in fact any more details other than the small picture, it is impossible to say if the gulley is not legally connected to a combined sewer system. I would however, be taking remedial action to prevent overspill from the pipes discharging into the gulley from damaging the surrounding brickwork.

    Thanks. The advice makes perfect sense. I have just purchased a McAlpine appliance trap from screwfix and will install it this weekend. I will look at the brickwork structure, thanks for the advice about that too Hugh Jaleak.

    UPDATE:

    Finished the remedial work and completed a test wash with no leaks found.

    I now want to clip the small section of pipe joining the trap to the waste pipe, but the clips need to stand off further from the wall than the white clips that came with the trap. Any idea where I can a few suitable clips from please?

    Thanks in advance.

    Find some thin strips of wood, cut to size and drill a couple of holes for the screw centres.

    And tie the hose loop bracket to the the pipe wall bracket to prevent the hose from working loose....it can result in a substantial flood as most washing machines will sit there trying to fill whilst the water runs out through the drain hose.

    For future reference, if clips need spacing from the wall, Plumbers use a couple of small pieces of 15mm copper tube, cut to required length, to act as spacers. (Appreciate not everyone has some lying about, but it's a handy trick if you have.)
