Fascinating subject:(
I think mine is a Winser.

When we first came to live here the vendors bequeathed us what I later came to know as a fatberg, and in clearing it I discovered this contraption. I figured out it was a u-bend (which you can't get a rod through although you can jet it, stand well back...) with a pipe above it for rodding beyond.
Somebody explained to me that it is supposed to keep smells and rodents from coming up your drains and soil vents, because the top hole is supposed to have a bung in it. It's quite usual for the bung to be missing, which mine is.
I've had to unblock the trap several times. Our drains haven't much fall and every blockage we have had starts at this trap.
When we built the new house we replaced all the drains up to the chamber this trap is at the exit of, and I had to unblock it again on Sunday, the giveaway being that the sink traps were all gurgling when a WC was flushed.
I think it probably blocked before we moved in, the first few yards of the blockage seemed to be suffused with white paint residue...the painter having left us 3 weeks ago.
I'm hoping that was a one-off, but I'm wondering if it will now be a chronic problem. All the WC's, taps and showers claim to be "water saving" so the flows will probably be lower, and parts of the new drains have the minimum fall or close to it.
Has anybody else had problems with one of these interceptors or replaced one? If I'm going to be doing this job monthly it will have to be sorted, no doubt at vast expense.
