Sewer tee made of polypropylene (PPR) 45 degrees d.110 x d.75 x d.110

The PPR (PP) sewer tee 45° Ø110×Ø75×Ø110 is a transitional T-shaped fitting for indoor drainage systems, designed to create a neat branch from a Ø110 mm main line to a Ø75 mm pipe at a 45-degree angle. This angle is widely regarded as the most practical for gravity drainage: wastewater flows smoothly without sharp turbulence, helping maintain stable flow capacity and reducing the risk of deposits at the junction. For this reason, 45° tees are often selected for nodes where reliability, quieter operation, and minimal blockage risk are key priorities.

The 110/75/110 configuration is ideal when the main run or stack is Ø110 and the branch needs to be Ø75—for example, when connecting a shared line from multiple draw-off points, creating a separate bathroom branch, or during remodeling in a house or apartment where drainage must be routed correctly between rooms. Ø75 is a convenient intermediate size: it provides better flow capacity than Ø50 and is used on sections where higher wastewater volume may occur (according to the system design).

Polypropylene (PPR/PP), from which the tee is made, is well suited for drainage applications: it does not corrode, and it resists moisture, domestic wastewater, and most cleaning agents. The inner walls are smooth—important for drainage because it helps reduce adhesion and buildup at branching points. The tee is designed for typical indoor drainage temperatures, including occasional hot discharges (up to 95°C), making it a practical choice for residential use and premises with active water consumption.

Installation is quick and convenient. Standard drainage joint geometry (socket/coupling depending on the version) allows the fitting to be integrated easily into an existing run. For a dependable connection, follow the basic rules: maintain the correct slope, clean the seating areas, insert the pipe to the installation mark, and avoid misalignment. The result is a leak-tight, serviceable, and long-lasting joint.

Advantages of the PP 45° tee Ø110×Ø75×Ø110:

smooth 45° branching reduces deposit and blockage risk;

Ø110 to Ø75 transition without extra adapters;

resistant to corrosion, moisture, and household chemicals;

smooth inner surface for improved flow;

ideal for repairs, upgrades, and non-standard drainage layouts;

suitable for apartments, houses, cottages, and commercial premises.

The PPR 45° sewer tee Ø110×Ø75×Ø110 is a reliable solution for proper indoor drainage routing when you need to branch to Ø75 while maintaining stable, “clean” system hydraulics.
