Every time I let the water out of my kitchen sink there is a really horrid smell (like rotten eggs).
Have checked the sink pipe and u bend thingy and that's clean (sink only plumbed in 16 months ago).
I think it's the drains. We have no outside uncovered drain here like we have at our old house but there is a drain cover on the patio. How horrendous is it to open them and check them yourself? :(
Is it hugely expensive to get someone out to do it?
