Purchased with the pump Seaflow accumulator tank- great combination, very smooth consistent water flow and volumes super low. Fantastic purchase

Excellent product. Super quiet, very easy to install, perfect fit for my setup, very well made. It comes with a rubber base to absorb vibrations which makes it quieter than it already is. I’ve been using it daily for about a week now without any issues. My daily use is basically to water my garden which takers about 30 minutes of continuous use and supply a toilet and a sink that are off grid. Suction head of my setup is about 2 feet and the other end head is about 10 feet, no issues at all, pressure is great and the auto shut off works flawlessly. Mine is powered by a small battery bank of about 50amps that is connected to a wind generator so is completely off grid. If you want a quiet, powerful, easy to install, great quality 12 volts pump; look no further this is the one you need!!!

Acheter pour remplacer ma pompe Surflo qui donnait des signes de fatigue après 6 ans de bons et loyaux services. La pression était correcte et le prix aussi. Cerise sur le gâteau elle est très silencieuse. Mais une cosse à l'intérieur du capteur de surpression devait être mal serré en usine. Résultats il a pris feu pendant que je dormais. J'ai été réveillé par une fumée et une forte odeur de brûlé. Le pressostat allait prendre feu alors que le fusible de 15 ampères n'avait pas bougé. Est-ce de la malchance ? En tout cas je n'ai plus confiance dans ce produit aux vues des autres commentaires...
