## 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

## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent little pump
*by V***T on 22 June 2022*

This pump pump works like a dream. Perhaps a little noisy but I don't have any comparisons. Care needed when fitting to the tap as the pressure is very high and there is a tendancy to leak under pressure unless you use the correct size jubilee clip. Two clips are supplied with the pump which work fine but you will need a third when fitting to the tap.

### ⭐⭐⭐⭐⭐ Good pump gor about 20 quid
*by P***  on 26 May 2025*

Fitted pump to a hymer motorhome works pretty well just make sure all clips are tight.

### ⭐⭐⭐⭐ Very noisy
*by A***R on 1 July 2025*

Works okay powering a small irrigation system for vegetable garden. Very noisy though !!
