Siphons Firenze and Siphons A-N branded REDI

The REDI brand PVC siphons are inspectable siphons for black water, gray water and white water, available from ø 50 to ø 500mm and are used for the discharge of civil and industrial water (white, black and mixed) to solve the problem of bad odors linked to underground pipes.

They must be installed outside the building and cleaning can be done simply by unscrewing the cap. The siphons for sewage are self-cleaning and predisposed for secondary ventilation and are available with both glued and plug-in (O-Ring) joint systems.

All REDI brand siphons are made using only quality raw materials (PVC =/> 85% of the total mix), with thicknesses and sockets according to EN1329 and EN1401 standards.

Where is the siphon positioned in Florence

All Italian municipalities have regulations to manage discharges into sewer systems and the general technical standards for sewer connection and use must be respected for the creation of a new connection to the municipal sewer system.

Generally, these guidelines provide for the implementation of a final sewerage inspection well before entering the municipal sewerage network. These inspection pits must contain an inspectable siphon, and for added safety, the installation of a non-return valve is also recommended.

The presence of an inspectable siphon will make it easier to clear the sewer in case of blockages, guaranteeing safety, cleanliness and efficiency of the system.

How to siphon a sewage sump

Based on the requirements set out in the municipal regulations, downstream of the confluence of the water drainage collection networks, an inspection pit must be positioned which can contain the Florence siphon or other monolithic siphon for sewage.

We recommend installing the siphon in an inspection pit so that it is easily accessible. From the siphon the pipe will continue up to the main sewer pipe to which it will be connected via a special, correctly sized clip, such as the EasyClip connection fitting.

How the Florence type siphon works

The siphon is a device that allows you to block bad odors coming from the drains, using a hydraulic flap. In fact, its task is to prevent it from rising thanks to its characteristic U-shape which creates a water stagnation area which constitutes a hydraulic cap.

The obstacle represented by the clean water trapped in the bend of the siphon blocks the bad smell coming from the sewer pipe in the case of the toilet or from stagnant water in the sink, bidet or shower pipes, preventing it from spreading into the bathroom.

The high siphoning stop with which the REDI brand A-N Siphons are equipped eliminates the risk of emptying the curve, definitively solving the problems of bad odors coming from the ducts.

Inside homes it may happen more frequently to perceive bad sewage odors, especially for those who live on the first floors, where the smelly rise from the drains is more noticeable.

This happens more frequently during the hottest seasons and in periods of great humidity, and for those who live on the first floors the situation is even more delicate, especially if the connection system to the sewerage network is not well implemented, the presence of the siphon A-N is more decisive than ever.
