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? Provides an effective and robust product for all plumbers, maintenance engineers, water companies, housing associations and the DIY market. You have several options if you cannot find your inside stop valve or if it's faulty and needs to be repaired. It provides an effective and robust product for all plumbers, maintenance engineers, water companies, housing associations and the DIY market. If isolating a mains water feed in a multi-occupancy building, save time notifying and inconveniencing neighbours

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: The diagram below shows the typical pipework for most homes and who is responsible for maintaining it. Save time cooling, draining down, refilling and returning to de-aerate – the bigger the system, the bigger the saving 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 InconvenienceOur 1/8” BSP comes with a ¼” chromed adaptor which is 1/8” BSP on the inside and ¼” BSP on the outside. 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?

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?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. 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. This is the 1/8” BSP model. We provide a 1/8” Micro model that will fit cast Iron ‘School Type’ radiators (made in cast iron or aluminium section). Aladdin Autovents are guaranteed for 5 years but usually last considerably longer. 4) How do I know when my Autovent needs to be replaced? Once your radiator begins to feel cold at the top, air has begun to build and the Autovent needs to be replaced. Our Autovents have a unique patented design which means at the end of the product life they will seal shut. 5) Don’t all Automatic De-aeration valves leak?

Aladdin Autovents reduce the volume of air/gas in radiators and helps to maintain their thermal efficiency, thereby reducing the fuel and energy usage. 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. 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? 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. 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?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. 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. 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?

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?

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. 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. 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.
