I live on the edge of a flood plain, and my rainwater downpipes drain into gullies around the house. Most of the drains then flow to a septic tank, but I can't trace one of them at all and think it flows into a stream or soakaway. When the river rises, water backs up the untraceable drain and out of the gully. I want to find a simple non-return system for the gully, perhaps one with a floating ball in, or one with a manually closable valve. My local builders' merchants and Plumb Center have no ideas, so I'm struggling. Can anyone advise suppliers or stockists, or other solutions? Thanks!

You can get non-return valves for underground pipeworks systems, but they are a specialist item, not something you'd find at Travis Bloody Perkins or B&Q.
You'd need to identify what type of pipework you have and then try somewhere such as Burdens, Cooper Clarke, UGS or similar. These are what we call "Civils Merchants" - they supply materials specific to the civil engineering trade (eg: large drainage pipes, manhole sections, road kerbs, ground engineering products) rather than general building materails, such as sand, timber and plasterboard (although some Civils Merchants can supply these, too)

Thanks Tony. Cooper Clark stock clay gullies with floating balls in them, which is just what I needed. Cheers.
