Description

Waterco Vacuum Relief Valve for Solar Pool Heating Systems

Essential Vacuum Protection for Solar Pool Heating

The Waterco Vacuum Relief Valve—also known as the Zane Solar Vacuum Relief Valve—is a critical component for any solar pool heating system. Designed to automatically protect your solar panels and plumbing from the damaging effects of vacuum pressure, this valve ensures your system operates safely and efficiently, year after year.

Ideal for both new installations and retrofits, the Waterco Vacuum Relief Valve is compatible with a wide range of solar pool heating setups, including flexible strip and rigid panel systems. Its robust, spring-loaded design delivers reliable performance in all weather conditions, making it a must-have for any solar pool owner.

🔍 Key Features & Benefits

Vacuum Protection: Prevents collapse or damage to solar panels and plumbing when water drains from the system.
Spring-Loaded Design: Ensures a strong, leak-free seal while automatically allowing air into the system when needed.
Universal Fit: Compatible with both flexible strip and rigid panel solar heating systems.
Durable Construction: Built to withstand outdoor conditions and constant pressure changes, extending the life of your system.
Easy Installation: Screw-in style valve that’s fully serviceable and simple to maintain.

🌬️ Why a Vacuum Relief Valve Is Critical

Prevents Vacuum Crush: When water drains out, a vacuum can form inside the panels and pipes. Without a vacuum relief valve, this can collapse tubing or crack PVC.
Automatic Air Intake: The valve opens when internal pressure drops, allowing air to enter and equalize the system.
Protects System Longevity: Reduces stress on collectors, manifolds, and plumbing—especially in long or elevated installations.

NCS installed our pool heating system and pool blanket in 2019 and have serviced both the heating system and the main pool pump system ever since then. They have always been very responsive whenever anything has needed to be done and always worked around our schedules to find a convenient time to attend. They always turn up on time and get the job done and follow up if anything can't be completed on the day. Pricing has always been very competitive and the team are great to deal with.

NCS Pool heating was good to deal with. There staff are friendly and helpful. After recent storm damage NCS dealt with my insurance claim to replace my damage pool cover. I am more then happy with their service delivery and installation of a new pool cover. I would recommend them for any pool heating supplies.

Communication was polite, prompt and helpful throughout. I received notifications throughout on estimated arrival times, due to weather interruptions. Service for removal and installation was professionally executed by two technicians. They did not waste time, or play music and cleaned up after them. Very satisfied. Highly recomend.
