Like most things plumbing related, quality has been replaced by cheaply made, mass produced rubbish. Size: ½” BSP (M) Marking: Aquaystem logo (‘Aquasystem’, where the ‘q’ is a silhouette of an expansion vessel) and other technical information on adhesive label on body. This Aquasysytem expansion vessel is a sturdy and easy-to-maintain system that's perfect for both potable water and heating applications. The vessel itself is constructed with an internal membrane that prevents water from coming into contact with the steel housing, easily .

I’ve isolated the vessel and opened Hot/Cold valves downstream and opened a hot/cold tap to relieve water pressure. Section: 1000 Expansion Vessels WRAS Approval Number: 2103337 Expiry date: 31/03/2026 Note: Expansion vessels should be installed in the vertical orientation and located so as to minimise the length of any connecting pipework. So happy with the speed this was dispatched because of reduced water capacity in my property due the defective old one. With a range of sizes available from 2l to 25l, these vessels come with a pre-charge valve for topping up air pressure and are WRAS approved.Since 2012, Aquasystem has been the institutional sponsor of the Aprilia racing team for the Superbike World Championship, a world that runs fast, fast and global like the evolution of the international markets.

Turn the black handles at either end of the flexible hose and wait for the pressure on the dial to read 1. We have a Valliant boiler, a Gledhill 250ltr tank and there is also a Boss 25ltr expansion vessel and another one and Aquasystem ARB24. The vessel itself is constructed with an internal membrane that prevents water from coming into contact with the steel housing, easily replaced without dismounting the vessel.

If water is required by the system, it starts flowing out of the tank without using the pump but just using the pressure in the air cushion. Came back to the boiler some time later to take a photo of the leak and noticed that gauge had dropped a bit and kept dropping for next couple of hours and now its almost back to 0.

We would always recommend that any work carried out following information or advice we have provided is done so by a fully qualified engineer. At this point the membrane is back to its initial dimensions, the pump starts again and a new cycle begins.The main purpose of an expansion vessel is to compensate for the increase in volume of water due to the varying water temperatures in hot water or heating systems. The expansion vessel allows for this extra space, as when water temperature increases the membrane inside the vessel inflates to allow the water to fill the vessel.

Once the system is working, the pressure of the pump lets the water filling in the bladder inside tank. The Advanced Water Reliance RWC aquasystem potable expansion vessel 24 Litre has a replaceable membrane that separates the water and air.
