A broads trap or bucan trap is quite common in local authority housing throughout the city. The idea behind them is to stop the foul odour from the main sewer coming back through the pipework by providing a water barrier similar to how a toilet operates.
However these traps also can cause problems with continual blockages occurring for various reasons such as debris falling in to the trap, waste such as St’s and wipes catching in the trap, and just by the trap becoming damaged over time like this one in Crumlin.
The pipework is also damaged as can be seen in the first photo so this also had to be cut out and removed.
In photo two we can see how the trap operates, the waste comes down the pipe into the well of water and then has to make its way around the u bend and off down the main sewer.
The concrete is shown in photo three, kangoed away to gain access to the pipework.
In photo four one of the pipes comes from the toilet/sink while the other one serves a gully which takes a down pipe from the gutter.
In photo five the pipes are made of clay and are a slightly different size to modern plastic pipework and a special fitting called a ‘clay to plastic ferenko ‘ has to be muted to marry them up.
An aj (small manhole junction) is seen in to leave an access point should there be any problems in the future.
The pipework and aj are now covered in photo six in concrete and brought up to ground level.
Looking very smart if I say so myself.
In photo seven the decking is now replaced with extra battons fitted for re-fixing.As you can see the aj cover is left accessible.
And the finished product, one would never know any work was ever undertaken here.
When your drain is starting to overflow and you decide to lift the manhole and all you see is a load of stones it usually means only one thing "You've got rats".Read Full Article
The tenant upstairs in this property in North Strand was oblivious to the fact that every time they flushed their loo it was dissappearing from their view but was re-surfacing up through the toilet downstairs. Alas the unit downstairs was un-occupied for a considerable period so nobody noticed events that were unfolding. The main sewer outlet was blocked so the waste had nowhere to go and found the easiest path....Read Full Article
