Review: Plumb in, plug in and off you go - Effective and very useful 12V pump installed for irrigation using water from a water butt via a mesh filter to avoid a detritus blockage. Good water pressure. Would not hesitate to buy again.
Review: Casing leaks - Used this to pump water into a washing machine, worked great although very loud, good flow rate etc. after a few uses water started seeping through the casing when the pressure sensor was activated. When disconnecting it to return it the plastic inlet and outlet connectors both sheared off.

## Questions & Answers

**Q: Can this be used to pump used engine oil?**
A: I don't see a reason why it should not be used for pumping used engine oil. I obviously have not tried it, but oil will not hurt its material, so go for it.

**Q: Hi, I have connect a 12v power source and pressure is very low. What do I need to do toget max pressure?**
A: The General Working Water flow is 3.5-4L/Min. If you need the pressure to be higher,
1. Use a regulator to adjust the pressure.
2. Use smaller caliber hose or spray gun to increase the pressure.

**Q: What size hose connectors would I need to fit to this?**
A: Hi James,  I am using a 1/2 " hose but did have to purchase adapters in order to fit the hose. Hope the attached video helps.

**Q: Can I use Hozelock connectors for input and output?**
A: No unless your using an 8 mm piper and the micro hose pip connector then you can feed in to hose lock but your get a 50% drop in pressure

### ⭐⭐⭐⭐ Works ok
*by R***B on 7 August 2026*

Seems to work ok. Quite as long as it's screwed down to something very solid like a brick. Some leaks to begin with be solved with a bit of fettling
