Onsen water pump
Excellent! Yor customer service rep Dominika was great to deal with and you are blessed to have her on your team; and dealing with your customers.

First one only lasted 1. /5 summer Hope I better results on this new one.

pression d'amorçage
Je suis satisfait très silencieux!:) cependant la pompe démarre dès que j'utilise de l'eau même si j'ai un accumulateur de 1 litre dans le système! J'aimerais savoir quelle est la pression d'amorçage de la pompe?

Great little pump
Works very well with the Onsen 5l shower system.

Camper pump
Installed easily and seems to be working well as a replacement for my old camper pump

Great product
Pump was delivered quickly and works great for my water cart

Cracked strainer
The pump works fine so far. However as soon as I hooked it up the strainer was leaking from 2 hairline cracks in the viewing glass. I opened the box when I first received it, but there is no way I would have noticed this before hooking it up. I called Onsen only to be told my 30 days warranty (really 30 days?) is up and that they recommend hooking it up as soon as you get it to check for defects. I'm not sure how this "recommendation" was supposed to be communicated to me. A new strainer costs $20 plus tax and shipping making it $48. The whole pump cost $100. I asked if anything could be done, like covering shipping, but no. Not at all happy with the service from this company.
Onsen
We’re sorry to hear about the issue that you experienced with the pump strainer. Although the pump itself is covered by a 2 year warranty, the accessories included with the pump are covered for 30 days. We recommend to our customers to inspect the pump and accessories soon after receiving it to ensure there are no missing or damaged components. However, we understand the frustration that this situation may have caused so we would be happy to make an exception and ship a replacement strainer.


Easy to Install
Super easy to install! Great for my tiny home conversion.

Bonne petite pompe
J'ai acheté cette pompe pour la brancher sur un réservoir (une "tote" de plastique de 1000 litres) pour pouvoir arroser mon potager avec de l'eau de pluie. La pompe fonctionne super bien! Je l'ai branchée sur une batterie à décharge profonde 12 volts et jusqu'ici je n'ai eu aucun pépin. J'ai assez de pression pour brancher un boyau d'arrosage et arroser tout le potager la conscience environnementale tranquille... Shipping très rapide!
