Frequently asked questions about the Sewerage category
Sewerage — what is it and which items are included in the "Sewerage" category on Sitypro.com?
Sewerage is the system of pipes and fittings for wastewater disposal; the Sitypro.com "Sewerage" category includes PVC sewer pipes and couplings (e.g. KAN.PRAGMA O.LIIT.PVC MUHV.110), elbows (75x45°), syphons, shower traps and 2000 L wastewater tanks.
What pipe diameters are available and how do I choose the right sewer pipe?
Available diameters include common sizes 32, 40, 50, 75, 110 and 160, plus larger drainage pipes (e.g. DRENAAŽITORU 160x140mm). Use 32–50 mm for household fixtures, 75–110 mm for internal stacks and external mains, and 160 mm+ for drainage systems.
What is the difference between couplings and tees (e.g. KAN.PRAGMA MUHV vs SEWER TEE)?
A coupling (KAN.PRAGMA O.LIIT.PVC MUHV.110) joins two pipes in-line; tees (SEWER TEE 75X50X45°) create a branch at 45° or 88°. Choose based on pipe diameters and the required branching angle.
What noise-reducing pipes and compensators are available?
There are noise-reducing sewer pipes (SEWER PIPE MÜRASUMMUTAV 110X2000) and compensating couplings (KAN.KOMPENS.MUHV MÜRASUMMUTAV 110). They cut flow and vibration noise and are suitable for 110 mm internal stacks.
Which linear shower traps are available and how to choose drain width?
Available linear traps include 700x70 mm and VENTO NAPOLI 600x70x70. Choose 600 mm for standard showers; 700–900 mm suits larger shower areas for greater flow capacity.
Are the syphons and traps suitable for baths and sinks?
Yes — items like SIFOONI ÜLEMINEK MCALPINE 11/4"X11/2" and VESILUKKO NORDLINE 11/4"-32MM fit standard baths and sinks. Always check the required thread size and outlet diameter for compatibility.
What options exist for external sewerage and drainage (pipes and tanks)?
For external systems there are profiled drainage pipes like DRENAAŽITORU 160x140mm 6M SN8 and 2000 L wastewater tanks with built-in filters. Choose SN strength class by load and tank volume by the expected collected water.
How to choose a pipe penetration seal for wall/foundation (e.g. KAN.LÄBIVIIGUTIHEND)?
Pick the seal by the nominal pipe diameter — options include KAN.LÄBIVIIGUTIHEND 110 and 160. The seal ensures watertight penetration into wall or foundation and must match the pipe outer diameter.
What's the difference between internal and external sewerage and what components are needed?
Internal sewerage uses syphons, stacks, couplings and tees for appliances (e.g. SIFOONI ÜLEMINEK). External systems use drainage/profiled pipes and tanks (DRENAAŽITORU 160x140mm) and require SN-rated products for load resistance.
