Automatic Water Fill Kit - 1/2" for Blue Thumb Elite Skimmers & Pump Canyon

Hudson Automatic Water Fill Kit - 1/2"

PB1342 – Perfect for Ponds and Pond-less Waterfalls

Keep your pond, Pond-less waterfall, or water feature running at the right water level with the Automatic Water Fill Kit - 1/2". This kit automatically replaces water lost from evaporation, helping reduce daily topping off and making your water feature easier to maintain.

As the water level drops inside the skimmer or Pump Canyon, the auto fill valve opens and allows fresh water to enter the system. Once the water rises back to the proper level, the valve closes. This simple automatic function helps protect your pump from running low on water and keeps your feature operating more consistently.

Designed for Blue Thumb Elite Skimmers and Pump Canyons

This auto fill kit is designed for use with Blue Thumb Elite Skimmers and Pump Canyon™ reservoirs. It is a great choice for pond and Pond-less waterfall applications where the water level can drop from evaporation, splash, wind, or regular use.

The kit connects to any 1/2" water line or garden hose, making it a convenient option for new installations or upgrades to existing water features.

How It Works

The auto fill valve works like a compact refill system. When the water level inside the skimmer or Pump Canyon drops, the valve opens and allows water to flow into the reservoir area. As the water level rises, the internal float closes the valve and stops the flow. This keeps the water feature topped off without requiring constant checking or manual refilling.

For best results, install the auto fill kit where it can accurately read the operating water level of the system. In most pond and Pond-less waterfall applications, that means installing it inside the skimmer or Pump Canyon reservoir area.

Important Water Pressure Note

This kit has a 30 PSI maximum water pressure. For reliable performance, Blue Thumb strongly recommends using the 30psi Regulator with this auto fill kit. Water pressure over 30 PSI may cause the valve to operate continuously, which can lead to performance issues.

What This Kit Is Best For

The Automatic Water Fill Kit - 1/2" is best suited for pond and Pond-less waterfall systems using Blue Thumb skimmers or Pump Canyons. If you are working with a decorative fountain basin or AquaBox® basin instead, see the Fountain Basin Auto Fill Kit - 1/2", which is designed for Blue Thumb fountains and smaller basin-style applications.

Replacement Parts Available

If you already have this auto fill valve and need replacement components, Blue Thumb also offers the Hudson Auto Fill Valve - 1/2" Rebuild Kit. If you only need the valve itself, see the HUDSON Auto Fill Valve 1/2".

Recommended Add-On

• 30 PSI Regulator - Helps reduce incoming water pressure to the proper operating range for the auto fill kit.

Bottom line: The Automatic Water Fill Kit - 1/2" is a smart upgrade for ponds and Pond-less waterfalls because it keeps the system topped off, helps reduce daily maintenance, and supports more consistent water feature performance.
