Waterco Alphaflo ECO-V Variable Speed Pool Pump

At a Glance

The Waterco Alphaflo ECO-V is a variable speed pool pump in 1hp and 1.5hp, with a permanent magnet brushless DC motor and three speed settings. Waterco quotes up to 80% energy saving when it runs on the low ECO speed for most of the day.

Ideal for

• Domestic pools where the pump runs all day and power cost matters
• Pools with a salt chlorinator or automatic dosing that likes long, slow circulation
• Pump pads close to the house
• Replacing a single speed Alphaflo with the same footprint and plumbing

Pool sizes are our guide, sized against Davey's chart for pumps of the same horsepower. Waterco does not publish a pool size for its pumps.

Why We Like It

Same body as the single speed Alphaflo, so it goes where an Alphaflo goes, with a brushless motor that lets you run it slow and cheap. Check the pipe size on the pad before you order, as Waterco lists the ports as 50mm in the brochure and 40/50mm in the price book. Pick the 100 for most domestic pools and the 150 when you run a heater or a cleaner. If you want the quietest pump, look at the Hydrostorm GEN2 ECO-VS.

Installation

It plumbs in at the equipment pad with the quick connect unions, flooded suction from the pool, so it sits at or below water level. Fit it yourself, or use a pool installer or plumber. Wiring to a fixed supply needs a licensed electrician.

Warranty & Support

3 year warranty on the pump, conditional on the install and use following Waterco's terms, with some wearing parts at 2 years and labour at 1 year. Commercial use is covered for 1 year.
