24V Brushless Water Booster Pump – Flow-Sensing Automatic Pressure Pump for Shower, Faucet and Water Heater Lines

Strong water pressure at the tap that used to trickle

A compact 24-volt brushless booster pump that screws into your water line, senses the water moving through it, and adds pressure the moment you open the tap. Made by AISITIN (model AST24-100W, printed on the unit), it runs from the plug-in adapter in the box and mounts on a wall with two screws. Put it on one weak shower, a faucet, or the feed to a wall-hung water heater and the difference shows from the first use.

It starts when you open the tap and stops when you close it

The built-in flow sensor does the switching. Open a tap downstream and the pump starts; close the tap and it stops. Set it once and forget it. For a fixture with a very gentle flow, the round button switches to manual mode and the pump runs on demand; press it again to go back to automatic.

The two lights on the front are labelled in the maker’s home language: the left one, 自动, is automatic; the right one, 手动, is manual.

A brushless motor built for long life

• Brushless, 100 W. A permanent-magnet brushless motor with Class H insulation (label), made for steady, repeat use.
• Low-voltage, plug-in. The pump runs on 24 V DC from the adapter in the box, which converts wall power to 24 V for you.
• Up to 7.9 gal/min (30 L/min). Strong flow for a shower, a kitchen faucet or a water-heater feed.
• Small and light. About 6.3 in tall by 3.3 in wide (16 × 8.4 cm) and 1.7 lb (0.76 kg), so it tucks in beside the fixture it serves.

Protected for heaters, utility rooms and sheltered outdoor spots

The housing carries an IP56 protection grade, and the pump takes water from 41 to 176 °F (5 to 80 °C), so it sits happily on the cold feed to a wall-hung gas or electric water heater, under a sink on the line to a faucet, on the supply to a shower, on the line from a rooftop solar water heater, or on the feed to a washing machine or bidet seat. Mount it in a utility room, laundry room, garage or covered outdoor spot, and let one pump look after one line.
