Connecting PVC Pipe to an Outdoor Faucet (UK Guide)

Adapting a Garden Tap for PVC Irrigation

In the UK, outdoor taps typically have a ¾" BSP (British Standard Pipe) hose thread, while PVC fittings use ¾" BSP parallel threads. The threads are similar but not identical, so a proper adapter is essential.

Recommended Adapter Configuration

1. Tap side: ¾" female hose thread (with washer) on a swivel nut.
2. PVC side: ¾" female BSP thread to accept a PVC male adapter.
3. Connection: The swivel allows the PVC line to hang freely without stressing the tap.

Product Example

Lasco Fittings part FHT-206 (or equivalent) provides exactly this: a swivel adapter with female hose thread on one end and female iron pipe thread on the other. Search "Lasco FHT-206" for details.

Alternative: Direct Glue Adapter

Some adapters screw onto the tap and have a solvent-weld socket for direct PVC pipe connection, eliminating a separate male adapter.

Installation Tips

• Use PTFE tape on the PVC male adapter threads.
• Ensure the washer seats properly in the swivel nut to prevent leaks.
• Support the PVC pipe within 12" of the adapter to avoid levering the tap.

With the right adapter, you can reliably connect a permanent PVC irrigation line to your garden tap.
