PP3 is Israel's most common triple-layer piping system for conveying sewage and wastewater inside buildings. This guide explains how to plan, select and connect PP3 components from Golan Industries — elbows, branches, covers and toilet nipples — in compliance with Israeli standard SI 1205 Part 4.
Quick Summary
✅ PP3 — Israeli triple-layer building system, resistant to odour and noise
✅ Elbows 45° and 30° — for bends within the sewage system
✅ Branch fittings — for connecting lateral drain branches
💡 All installations must comply with Israeli standard SI 1205 Part 4

What to prepare before you start? 🧰
Before planning a sewage system: Adjustable toilet nipple 110 mm to connect the toilet to the floor pipe. PP3 elbows 30° and 45° for bends inside the wall. PP3 branch fittings 45° and 87°30' for lateral connections (sink, shower). Reducing branch 87°30' for diameter changes. PP3 cover to cap unused system ends. Plan the pipe route first and count how many bends are needed.
⚠️ Important before you start
In-building sewage installation in Israel must comply with SI 1205 Part 4. Non-compliant installation can cause sewer odour returning into the apartment and wall structural damage. Consult a licensed plumber at the planning stage.
Step by step 👷
- Plan the pipe route: Sketch every endpoint (toilet, sink, shower) and the exit point to the main stack. Every pipe must slope 1-2% (1-2 cm per 1 m). 2. Install toilet nipple: Insert the adjustable toilet nipple 110 mm into the floor pipe. Adjust height to match final floor level after tiling. 3. Install elbows: For a 45° turn — use a PP3 elbow 45°. For a gentler bend — PP3 elbow 30°. Ensure the elbow is pushed fully into the socket to the depth mark. 4. Connect branch fittings: For a sink connecting to the main run — branch 87°30'. For a more comfortable angle — branch 45°. 5. Double branch: For two drains joining at the same point — double branch 67°30'. 6. Sealing: PP3 connects as a push-fit socket-and-spigot joint — no adhesive needed. Ensure full insertion to the socket. 7. Check slope and seal: Fill each end with a bucket of water and verify full flow and no leaks at connections.
💡 Pro tip
Experienced plumbers warm the spigot end (not the socket) in sunlight or with a heat lamp before insertion — it slides in easily and fits tighter against the socket after cooling.

What is the difference between a 30° and a 45° elbow?
A 30° elbow is for gentle turns in tight wall spaces. A 45° elbow is for sharper turns. Two 30° elbows can be combined to achieve 60°.
What is a reducing branch?
A standard branch connects a lateral at the same diameter. A reducing branch connects a smaller-diameter lateral (e.g. 50 mm side drain) to a larger main run (110 mm).
Does PP3 require adhesive?
No. PP3 uses push-fit socket-and-spigot joints with no adhesive. The spigot is pushed into the socket and self-seals by compression.
Conclusion
A correct sewage system saves costly repairs down the line — plan right with PP3 components from ramo.co.il to Israeli standard.
