🚿 Excessively high water pressure can destroy a tap, burst a flexible hose, and cause thousands in damage — usually with zero warning. A safety valve and pressure reducing valve are the two simple components that protect your entire plumbing system. 🛡️ In this guide we explain the difference between these valves, when each is legally required in Israel, and how to choose the right product — without overpaying. 💡 All products mentioned here are available for immediate purchase with fast delivery nationwide.
Quick Summary
- 🛡️ Safety valve — protects the boiler and heating system from overpressure and backflow
- 💧 Pressure reducing valve — reduces high inlet pressure to a safe, efficient level
- ✅ TESA Valve (₪41.5254) — safety valve + check valve in one — our top recommendation
- 🔧 Simple installation — in most cases just a few minutes of threading
- ⚠️ Required by standard — for solar boilers and heating systems, a safety valve is a legal obligation
Safety Valve vs Pressure Reducing Valve — What's the Difference? 🤔
A Pressure Reducing Valve (PRV) is installed at the water inlet point of a building. Network pressure in Israel can reach 10 bar or more — far above what taps, flexible hoses, and appliances can withstand long-term. The valve reduces pressure to 3–4 bar, extending the life of your entire plumbing system and reducing water waste.
A Safety Valve (Relief Valve) is a completely different component — installed near the boiler (solar, electric, gas) and acting as an emergency pressure-release mechanism. As water in the boiler heats up, it expands and pressure rises. The valve automatically opens and releases water to prevent explosion. This is not optional — it is mandatory under Israeli standards.
A Safety Valve + Check Valve combines both functions in one body: it both releases overpressure and prevents contaminated water from flowing back into the water network. The TESA valve is exactly this solution — at just ₪41.5254.
⭐ Top Pick: TESA Safety Valve + Check Valve — ₪41.5254
The TESA Safety Valve + Check Valve is the smartest solution for solar boilers and heating systems: safety valve + check valve in one body, meets Israeli standard requirements, suitable for DIY installation, and exceptionally affordable. It's what most plumbers recommend — and you can order it directly with one click. 🛒
When Is a Safety Valve Required in Israel? ⚠️
Under Israeli Standard SI 1205 and plumbing regulations, every water heater (solar, electric, gas) must be equipped with an approved safety valve. A boiler without a safety valve is a safety failure that can endanger lives and void insurance.
When else is a pressure reducer recommended? If your home water pressure exceeds 5 bar — signs include taps that blast water forcefully, bulging flexible hoses, or noise in the pipes. High pressure causes gradual damage that accumulates into expensive repairs.
Who needs a more advanced reducer? High-rise buildings, homes connected directly to the municipal network without a tank, and industrial sites — all benefit from a quality reducer. The Brockmann German pressure reducing valve fits ¼–1 inch pipes and offers German precision at ₪269.49.

View productHow to Install a Safety Valve — Quick Guide 🔧
In most boilers installed in Israel, the safety valve is fitted on the cold water line before the boiler — typically a ½ inch connection (the most common). The TESA valve comes ready for direct connection with standard male/female fittings.
Basic installation steps: 1️⃣ Close the main inlet valve. 2️⃣ Release pressure — open a hot tap in the house. 3️⃣ Remove the old valve (if present) with an adjustable wrench. 4️⃣ Wrap PTFE tape (2–3 wraps) on the thread. 5️⃣ Thread the new valve in the correct direction (there's an arrow indicating flow direction). 6️⃣ Open the inlet valve and check for leaks.
💡 Tip: If you have no plumbing experience — a professional plumber will install the valve in 15 minutes at low cost. However, buying the product yourself typically saves ₪50–100 compared to purchasing through the plumber.
Frequently Asked Questions 🙋
What's the difference between a safety valve and a safety valve + check valve?
A safety valve alone releases overpressure but doesn't prevent backflow. A safety valve + check valve (like the TESA valve) does both — it's what plumbers recommend and what new installations require under standard.
What is normal water pressure in Israel?
Municipal water pressure in Israel ranges between 3 and 10 bar depending on area and altitude. The ideal in-home pressure is 3–4 bar — sufficient for all normal use without causing damage. If your pressure exceeds 5 bar, a pressure reducing valve is strongly recommended.
Does the boiler safety valve need periodic replacement?
Yes. It's recommended to replace the boiler safety valve every 5–7 years, even if it looks fine. Over time the internal spring loses tension and may not open when needed. Annual check — gently turn the red/yellow handle (if present) to verify the valve isn't stuck.
What's the difference between the Italian and German valves?
The Italian valve (₪122.88) is an economical, reliable solution for homes and apartments — simple installation and good durability. The Brockmann German valve (₪269.49) suits commercial use, industrial facilities and large systems — higher precision, wider pipe diameter range and longer product life.
Can I install a safety valve without a plumber?
Yes — in most cases a safety valve can be installed without a plumber if there is easy access to the pipework and no infrastructure changes are needed. Installation requires only an adjustable wrench and PTFE tape. However, for a new boiler — a licensed plumber is recommended for the initial installation for warranty purposes.
Conclusion
🛡️ A safety valve and pressure reducing valve are the smallest investment that will protect you from the biggest damage. The TESA Safety Valve + Check Valve at ₪41.5254 is the leading solution for solar boilers and heating systems — standards-compliant, reliable, and ready for immediate installation. ⚡ Don't wait for the next failure — order now!
