Why Rainwater Harvesting Matters

Collecting and reusing rainwater is a simple yet impactful way to reduce water consumption in your garden. According to the U.S. Environmental Protection Agency (EPA), rain barrels can save homeowners around 1,300 gallons of water during peak summer months.

How to Install Your Replacement Tap

2. Remove the old or damaged tap by unscrewing it from the tank fitting.
3. Wrap the threads with PTFE tape (plumber's tape) for a watertight seal.
4. Screw in the new plastic tap firmly by hand until snug.
5. Refill your water butt and check for any leaks.

Frequently Asked Questions

Q: What size water butt or rain barrel is this 1/2 inch plastic tap compatible with?

A: This replacement tap features a standard 1/2 inch BSP (British Standard Pipe) thread, which is compatible with the vast majority of water butts, rain barrels, and outdoor water storage tanks that use a 1/2 inch outlet. If you are unsure of your current fitting size, measure the outer diameter of the existing tap thread — a 1/2 inch BSP thread has an outer diameter of approximately 20.9mm.

Q: How do I stop the plastic tap from leaking after installation?

A: To ensure a watertight seal, we recommend wrapping the tap threads with PTFE plumber's tape before screwing it into the tank. Hand-tighten firmly and avoid over-tightening, which can crack the plastic. If minor dripping persists, apply an additional layer of PTFE tape. Always install the tap with the water butt empty to make fitting easier and safer.

Q: Is this plastic tap suitable for drinking water or only garden use?

A: This tap is designed primarily for garden and rainwater harvesting use — such as watering plants, filling watering cans, or general outdoor water management. It is not certified for potable (drinking) water applications. For best results, use it with a dedicated rain barrel or water butt for garden irrigation purposes.
