On a Closed, pressurised system: After the air absorbed in the water has separated, the best early indicator of a leak is a drop in pressure of the system. An Autovent should, if anything, lead to a faster drop in pressure so an even earlier indication of a leak. Using your inside stop valve should be easy and you should be able to operate the valve yourself. How to turn your water off using the inside stop valve

It may take a few turns to stop the water. You'll usually get to a point where you can’t turn it anymore. You shouldn’t need to use excessive force to turn it further. A CenterRad Centerbrand radiator has a little well on the end of the roll top radiator facing end out from the radiator. This also uses the Micro Barlo. This valve needs no oring seal but seals on the cone end of the valve stem.BSP is approximately 14.5mm. If you use the ¼” BSP thread for your radiator, then it will need PTFE tape fitted on the outside of the bush.

Yes, this is possible. Some plumbers suggest that on the suction side of the pump micro-gaps in joints could allow air ingress, yet when the pump is off (and the pressure equalises to the c. 1.6 bar of normal operation) the micro-gaps are too small to allow water egress. 10) Can corrosion inhibitors be used with an Autovent? If a system continues to lose pressure after the first 2 weeks or so of being filled, this can only be due to water loss, i.e a leak. 9) On a Closed system, can a radiator continue to collect air without there being a water leak? Yes, provided the temperature of the piping allows the valve to operate at 35°C for the Hygroseal™ Autovents. 14) Can the valves work on negative pressure systems? Also can be used when you need to isolate a mains water feed to a multi-occupancy building or to maintain a component in a heating system. Save Time and Inconvenience Yes, the EasyFit Isolator is designed to be fitted to live pipes hot up to 85°C or cold pipes. 2. When the EasyFit Isolator cuts into the pipe what happens to the piece of pipe which is removed?The EasyFit Isolator saves time cooling, draining down, refilling and returning to de-aerate. The bigger the system, the bigger the saving. No more freezing kits and the risk that an ice plug will fail. No. Aladdin Autovents do not leak. The Hygroseal™ range is guaranteed to operate for 5 years and guaranteed leak-free for life. All Aladdin Autovents contain a patented mechanical valve that closes to a water-proof seal when water gets to the internal mechanism of the valve. 6) Can I fit Autovents to a new system? Unable to freeze flow of water, you can still install EasyFit to pipes with moving water, without the need to turn off the main external / internal service valve. The EasyFit Isolator is a full-flow valve which reduces flow by just 2% (@ 5 bar 30 lit/min) so flow will be 98% of the flowrate prior to fitting the valve. 4. Is the EasyFit Isolator guaranteed?

It may take a few turns to turn the water on. It may also take a few minutes for the water to start running from your taps, as it will need to run through the pipes again.Save time cooling, draining down, refilling and returning to de-aerate – the bigger the system, the bigger the saving Our 1/8” BSP comes with a ¼” chromed adaptor which is 1/8” BSP on the inside and ¼” BSP on the outside. Your property will likely have several stop valves inside your home. You will likely be able to turn off your water for the room or area of your property where you have a leak, or you’re doing some plumbing. This means you can continue to use your water in the remaining rooms of your property. Your inside stop valve is inside your house and is normally located just after the water pipe enters the house. This is often under the kitchen sink, but can also be: You have several options if you cannot find your inside stop valve or if it's faulty and needs to be repaired.

The first time radiators fitted with Hygroseal™ Autovents are filled, the air hisses out until water hits the hygroscopic washers and then they seal (you will often see a small “bubble” of water after the first fill). If more air/gas builds up in the radiator, it will not escape until the hygroscopic washers have dried a little and have shrunk enough for gas/air to escape. The time it takes for the washers to dry and shrink varies according to system pressure, temperature and humidity. b) where a radiator is higher than the water tank, in which case when the pump stops running a vacuum forms (e.g in loft conversions).An accredited plumber can use freezing and clamping as a short-term solution. This process creates an ice plug that lasts for around 30 minutes, allowing you to extend or repair pipework without draining the whole system. This guide should answer most questions asked regarding the Aladdin Autovents. 1) How do I find the correct sized Aladdin Autovent valve for my radiator? If isolating a mains water feed in a multi-occupancy building, save time notifying and inconveniencing neighbours On a header-tank system: Air can enter the system through micro-gaps in joints etc, without a leak, but in some cases a leak could lead to air collecting in one radiator. In those cases fitting an Autovent might delay the identification of a leak. On such systems, NLB recommends that Autovents should be fitted to installed radiators that have a history of collecting air if no leak in the system has been identified.
