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. 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. 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. 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: Our 1/8” BSP comes with a ¼” chromed adaptor which is 1/8” BSP on the inside and ¼” BSP on the outside.

For this model and all other models to manually vent, you need to unscrew the entire valve half a turn. At the end of life, you switch off the radiator valves and remove the valve. There is also a circular ½” BSP valve (Antrax) which has 3 side ports that allow a U key to be used to rotate the valve and screw in/unscrew from a radiator.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 We have two 6mm models. One is called the Micro Barlo which has an extended length thread and a conical tip. The other is the Micro 6mm which has a short 6mm thread.

Even when you can’t freeze you can still EasyFit to pipes with moving water, without the need to turn off the main external / internal service valve. Install a permanent isolation valve called an Aladdin valve. This can be installed on hot water or cold water pipes in around 5 minutes and can be done without turning off your water. 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. 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. Fitting Aladdin Autovents to radiators helps increase efficiency by eliminating gas and air from radiators automatically.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 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? If isolating a mains water feed in a multi-occupancy building, save time notifying and inconveniencing neighbours Yes. Fitting the Autovent should reduce the need for corrosion inhibitors, but we do recommend their use because corrosion leads to further gas collecting in the radiators. 11) Can leak-stop products be used with the Autovent? 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?

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. 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. BSP (British Standard Pipe) plumbing thread allows a ½” tube to pass inside the thread which approximately has a 20.8 mm outside thread on it. The inside is around 18.6 mm and inside that size a ½” 12.7mm pipe will pass. 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). Aladdin Autovents reduce the volume of air/gas in radiators and helps to maintain their thermal efficiency, thereby reducing the fuel and energy usage.We have a Micro 7mm which has a short thread that fits the CenterRad radiator where the tapping is at 45° to the radiator. 2) How do the Autovents work? Provides an effective and robust product for all plumbers, maintenance engineers, water companies, housing associations and the DIY market. 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?

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? The standard radiator tapping size for Panel Radiators and Towel Radiators (80% of market) is the ½” BSP tapping.It may also take a few minutes for the water to stop running from your taps, as there will be some water left in the pipes from before you turned the water off. The diagram below shows the typical pipework for most homes and who is responsible for maintaining it.
