Nice little pump.
Nice little pump (for my motorhome). As others say it’s a bit noisy but it obviously only comes on when you turn on a tap so no big deal. You’ll need some internal diameter (ID) 8mm pipe to push over the inlet/outlet (available on Amazon) and 100% attach some jubilee clips over the pipe as mine pushed off under pressure when testing. Others have said that it’s not clear anywhere in the instructions which is inlet and which is outlet, that’s certainly true and I also got it wrong the first time but then frustratingly spotted a tiny arrow (with my glasses on !!) on the body of the pump to indicate the water flow direction (see my photo to save yourself the guessing.

Powerful and quiet
Had to replace a pump bringing water from an ibc 200m away to provide water for a tap and toilet. This is connected up to 20mm blue pipe and pumps very well, gives a good flow and cuts off when the tap turns off.I was worried it might not have the power, but it does.

Hose connection
It required a 33mm hose which can be ordered from here - lay flat hose - or fishpond hose. However, I used a 21mm grey washing machine drain hose from Screwfix as they have rubber cup ends which stretch to fit perfectly over the inlet and outlets, are very flexible and are reasonably cheap and readily available. Worked a treat for me,

Great product
2nd one I've purchased for my children's water wall. The previous one lasted 5 years outside with lots if use but sadly the rubber perished so replaced with new one and hopefully another few years of use

Not clear connection instructions
No instructions on which is the inlet and outlet water connection s.Right or left .This is important info when fitting in campervan. So I will have to guess and hope I'm OK.Ridiculous to omit this info
