Holman Poly Irrigation Air Release Inline Valve

Description

The two main reasons for an air release valve are: 1. A means of releasing air from the drip line when the system is turned on. Eliminating any air pockets. 2. To allow air to freely enter the system when it is shut down. This ensures a vacuum does not draw debris into the drip line via the dripper outlets. This condition is known as "suck back". Suck back can cause the drip line to collapse or potentially draw in dirt and block the dripper. Installation: To install an air release valve, ensure you have a 19mm x 1/2" BSP female iron tee at the start of your system. The air release valve screws into the 1/2" BSP female thread of the tee piece. This valve connection is normally located after the pressure reducer assembly as this is often the highest point in the drip system. It is important to install the valve at the "highest point" in the system to allow it to work correctly. If your tap & filter is lower than the irrigated landscape, ensure your air release valve is suitably located at the highest point. Install one air release valve for every 40Lpm of water flow used in your system. NOT SUITABLE for low pressure applications. The valve needs minimum operating pressure of 7 meters (70kPa to operate).

We ship to addresses across Australia from our network of warehouses and suppliers. A small number of remote locations may not be eligible for delivery. If your address is one of them, we'll let you know promptly.

Your order may be sent from a wholesaler, warehouse or retailer partner, so the packaging may not always show the DEAL FIRST name.

Shipping costs are calculated at checkout based on your delivery address and order. You'll see the total before you pay.

Special Orders and Backorders

Special order products refer to items that are not standard inventory or items currently out of stock that must be requested directly from an external supplier. By placing a special order, you acknowledge and agree to the unique processing restrictions outlined below.

Unlike standard stocked items which typically ship within 1–2 business days, special order items require additional fulfillment timelines.

• Standard Stock: Dispatched within 1–2 business days.
• Special Orders / Backorders: Expected dispatch ranges between 5 business days to 4 weeks, depending on supplier availability and transit logistics.

Any estimated delivery windows provided at the time of purchase are guidelines and subject to supplier supply chain fluctuations.

Delivery Times

Estimated delivery times, counted from when your order is dispatched:

• Metropolitan areas: 2 to 5 business days
• Regional areas: 2 to 7 business days

Tracking

Once your order ships, we'll email you a tracking number where the shipping method supports tracking. Larger orders may arrive in more than one parcel.

If your parcel hasn't arrived within the estimated time, or tracking hasn't updated for several days, please contact us with your order number and we'll follow it up with the carrier.

Special Order and Backorder Cancellations

Once a special order or backorder is placed with our supplier, the order cannot be cancelled. Cancellations will only be authorized if the supplying manufacturer permits a penalty-free cancellation to us. If any supplier administrative fees or restocking fees are incurred during a requested cancellation, these costs will be passed on to the customer.
