Jobe Rojo Partfill Float Valve – Low-Flow Top-Up Valve for Rainwater Harvesting Tanks

Ships directly from the manufacturer.

The Jobe Rojo Partfill Float Valve is a low-flow float valve made for rainwater harvesting tanks. During dry spells it automatically keeps a low reserve of water in the tank from your mains or pump supply — so the services fed by the tank keep running, while leaving capacity for the next rain to fill.

Here's how it works: as the tank empties, a weighted float travels down its 8.2 ft (2.5m) cord and sits on the bottom stop, which opens the valve. The valve runs until the float lifts clear of the stop, then simply rises and falls with the water as rain fills the tank — so the Partfill only tops up when rainfall isn't enough.

The valve installs through the side wall of the storage tank, above the overflow level to prevent backflow, and Jobe rates it for all makes and models of rainwater harvesting tanks. It's compatible with trickle-flow restrictors, has a built-in non-return valve, and locks off with a lock-off switch.

Available in 1/2" and 3/4" inlets, both supplied with a long tail and backnut, the Rojo Partfill is compact and built from non-corroding materials.

Frequently Asked Questions

Will the Partfill fill my whole tank?
No — that's the point. It keeps a low reserve so services fed by the tank keep running, and leaves the rest of the tank's capacity for rainwater.

Where should I mount it?
Through the side wall of the tank, above the overflow level. Jobe recommends keeping the overflow, rainwater inlet and pump outlet as far from the float valve as possible.

Can I use a flow restrictor?
Yes. A trickle-flow restrictor before the valve won't cause it to malfunction.

Need more flow?
See the high-flow Jobe Topaz Partfill Float Valve.


Save the space for the rain, keep the water flowing — the Jobe Rojo Partfill takes care of the dry spells.

Great quality Ploybraid and good for about 4-5 years year round application with uv exposure.

This is my second purchase of the super 9 polybraid, and it sure won’t be the last. Compared to the other poly wire products I’ve used, this braid is so much more durable, easily visible to the livestock, and VERY conductive. The smooth braid is much smoother to reel in than the other poly wires I’ve used, and for almost a year I’ve been moving cows with this wire at least three days a week. Still going strong with no viable signs of wear. I highly recommend this product. 5 stars for sure

It is working great. Running on a deep cycle battery that drops to 50-60% in 4 days on electric netting. 8-10k volts on poly rope and 4-6k volts on the netting.

This Range Ward — Power Reel saves me so much time and headache. I wish I would have made this purchase years ago. Just attach it to your side by side and go. It's that simple.
