We had problems with flooding in our back garden a couple of times in the last few years. We had a drain company out who said they could install a non-return valve in the pipes.
I was wondering if anyone has had any experience of these, or heard of any problems with them. From some research on the web, I found one person who said they can become clogged and need some maintaining, but it would still be worth it to know it would prevent my flooding problem (water mixed with sewage!)
