Blocked drain?

[rodders]

Hi everyone,

Whats the best way to check if the drain is blocked. I got called to a school with a sink that wouldn't drain. I took off the bottle trap and it was full of sand. Cleaned it put it back on and now it still doesnt drain. Took it off again checked it, still not draining. Theres an slight bad smell also in a few rooms near the sink. They wouldnt let me lift the man hole covers as it was polling day and people walking around so have to go back in a few days and check it. Whats the best way to make sure of this? Theres no other sinks etc near this one, otherwise I would have run it and seen if it is running in the man hole, but its just a cleaners sink by the look of it.

Cheers

Best way as you say is to lift manhole covers!

They obviously aren't that bothered about it if they wouldn't let you lift covers to inspect. It is an environmental health issue but that obviously doesn't bother them.

Make sure you charge them for all visits you make, it's not your problem they didn't want it investigated properly on initial visit!
