The right plumbing infrastructure prevents leaks, water damage and expensive repairs. This guide explains how to install a two-way angle stop valve, a safety valve with check valve, and how to fit a recessed wall manifold cabinet — in accordance with Israeli standard IS 1205.
Quick Summary
✅ Two-way angle stop allows isolating each water point separately — mandatory in new apartments.
💡 Check valve prevents backflow — mandatory near water heaters.
⚠️ Before any plumbing work — shut the main stopcock.
🔧 Recessed 16-outlet manifold suits average apartments with 2–3 bathrooms.
📦 Safety valve + check valve in one set = saves time and cost.
What You Need Before Starting 🧰
Prepare: adjustable wrench or pipe wrench, PTFE tape (Teflon) for sealing, 1/2" two-way angle stop valve (SPRING chrome, ₪35), safety valve + check valve (Tesa, ₪49), and manifold cabinet for distributing water lines. Make sure the main stopcock is closed before starting.
⚠️ Warning Before Starting
Always close the main stopcock before any plumbing work. Open a nearby tap to release residual pressure before disconnecting fittings. Unreleased pressure will cause a strong water spray.
Step by Step — How to Do It Right 👷
Step 1 — Preparation: Shut the main stopcock. Open a nearby tap to release residual pressure.
Step 2 — Remove old valve: Turn counter-clockwise with a wrench. Wipe the pipe end.
Step 3 — Apply PTFE tape: Wrap 3–5 turns of PTFE tape clockwise onto the pipe threads. PTFE prevents leaks at the joint.
Step 4 — Install two-way angle stop: Thread the 1/2" angle stop by hand first, then tighten with a wrench — no more than 2 turns past hand-tight (overtightening cracks plastic fittings).
Step 5 — Install safety + check valve: Mount the safety + check valve (Tesa) on the inlet line to the water heater. Note the flow direction arrow on the body.
Step 6 — Test: Open the main stopcock slowly. Check all joints using the white towel method: place a white cloth on each joint for 5 minutes. Any dampness = tighten slightly more.
💡 Pro Tip
A two-way angle stop allows isolation from a distance — great advantage in closed manifold cabinets. In new construction: plan an angle stop at every outlet, so future repairs won't require shutting off the whole apartment.

Frequently Asked Questions ❓
When is a check valve required?
A check valve is mandatory on the inlet to an electric water heater — without it, pressure from a heated tank can push water back into the public supply. Required under Israeli Standard IS 1205.
How many outlets does a manifold cabinet need?
An average 3-room apartment needs 8–12 outlets: kitchen (hot+cold), 2 bathrooms, washing machine, garden tap. A 16-outlet cabinet suits larger apartments with room for future expansion.
