Channel drain with no U bend

ronn

I got a channel drain installed directly into the sewer, the lad who fitted never bothered his boll0x to put a trap on it to stop the smell coming back up,
I've discovered this after all the footpaths have gone in,

I've yet to drill a hole to allow the water into the sewer,
I'm wondering is there something like rubber washer/diaphragm, when enough water lands on it it opens and allows the water flow out then closes not allowing the smell back up,
Or some other solution I'd be great full of any suggestions,
Thanks

I fear you may have a much bigger problem, but as I don't live in your area, I don't know what the requirements are in relation to foul and storm water segregation, it varies from area to area.

I am assuming that the channel drain is to get rid of rain water from an outside area, and it is very possible that you are supposed to segregate storm water and foul water into separate drainage systems, to avoid overloading the waste water treatment plants with water that needs no processing.

If that is the case, then connection of your channel drain to the sewer will not be appropriate.

If your area is on combined drains, then the only answer to the issue will be to put in the right size trap at the end of the channel drain where the pipe outflow is connected, and yes, that may mean some significant disruption to the area around it.

Thanks Steve, not the news I was hoping for :-). I'll drill some small holes in the pipe and see how it goes,
