Smart Joint produce a complete range of pipes, fittings, hidden cistern, and other spare parts for Kitchen & Toilet Drainage System, Siphonic Drainage System.
In 2017, Smart Joint has developped popular sizes Electrofusion fittings such elbow, tee, reducer, ect. compare to spigot fittings in the past, it save the cost and easier for the installation.
Siphonic drainage is actually very simple in principle and all systems work in exactly the same way. Baffle plates inserted in the outlets restrict air entering the top of the system which, when combined with carefully sized pipe work, causes the system, horizontal and vertical, to run full. In a very similar way to a simple tube siphon (such as you would use to empty a fish tank), the action of water dropping down the down pipe will cause a negative pressure to form at the top. This negative pressure can be harnessed to suck water along a collector pipe installed horizontally connecting the outlets at high level. The benefits this gives are:
Each gutter will have only one or two down pipes, and these can be located at the end of the building, allowing free use of floor space by eliminating down pipes and therefore reducing columns.
The horizontal collector pipe can be very close to gutter, allowing full use of internal space.
Underground drainage can be eliminated internally in building, and can be significantly reduced externally, which can provide considerable cost savings and enhance construction programmed on all sites, and particularly contaminated ones.
Siphonic drainage will allow water to be delivered at a designated point at shallow depth, which can significantly reduce the construction costs, especially for pond based solutions.
With the improvement of the drainage of kitchen and toilet, the traditional ground drainage system begins to show various shortcomings, the drainage exchange of the up and down stairs, the odor exposed from floor drains, sewers, the hidden dangers of water leakage and many other problem need be resolved. When the design on the wall drainage system appears, it makes the drainage of kitchen and toilet reach a new height, thus solving the above problems and making the substantial savings of water.
The whole system includes four major parts:
HDPE sewage fittings &pipes
Floor drains & trap
Flush control plate
