Hi,
First time poster, I apologise that it has to be a question...
I'm having my patio relaid and the builders have replaced the single naff drain with a strip of Aco along the lower edge, so far so good! The problem is that it looks (or sounds) like they have just dropped straight onto the pipe which is a combined drain as we don't have storm drains just combined soil/surface.
I say sounds as you can hear the water from a toilet flush if you bend down near the drain.
My question therefore is... is this likely to cause a problem longer term (we are first on the sewer run if that makes a difference so nobody else's foul matter runs past us).
Should I insist they rip up the newly laid patio to put some kind of trap in?
Is there something that can be retrofitted into the Aco outlet from the top that would be like a one way valve?
TIA
