An Air Admittance Valve is an ingenious device that allows a soil stack to terminate inside a building. AV110 Internal air admittance valves are installed onto the soil pipe using a solvent weld joint. Click here to watch a short video on the use of Air Admittance Valves.

All of our Air Admittance Valves are Kitemarked and conform to BS12380:2002.

The one-way valve opens to allow air in to the soil system when required to balance negative pressure, but without allowing any foul air to escape. The valve must be fitted at least 200mm above the highest wet point in the soil stack, ie. the highest point in the system that water can reach. Valves can be left on show or hidden within a duct, cupboard or loft space.

Our Returns Policy For Cast Iron Products From Hargreaves Foundry Products

If you wish to return any of our Cast Iron products, then please contact us as soon as possible. We can then liaise with the manufacturer and issue a returns form which will need to be returned to Hargreaves alongside the products. Our cast iron products come direct from Hargreaves Foundry (HF) in Halifax so returns will need to go directly back to them.

All return requests must be notified within 90 days of the goods being dispatched from HF and all damaged items must be notified within 24 hours of receipt of goods. All items must be returned in a saleable condition. Once agreed, the goods must be returned within 14 days from the date stated on the Return Form.

Please note that any bespoke items or specially painted RAL coloured items or Mech 416 Soil System pipes are non-returnable. Please be aware that all returns for Cast Iron Gutters and Soil & Drainage will incur a re-stocking charge of between 25% & 30% for exact details please view our Hargreaves returns policy.

The % charged is based on the net selling price of the original goods - this charge is unfortunately out of our control as it is levied on us by the manufacturer.
