In-line water pump.

Can anyone recommend a inline water pump so I can connect my water butt to my pw,for some reason my k5 won’t fire up with just gravity feed even though the W/butt is higher than my pw,I have to connect hosepipe from tap to fire up then quickly change to hose from tap to w/butt but if I let go of trigger on pw I have to repeat process again which is annoying.

Andy.

That's 12v so you will need to run it off a battery or a power supply.

Your karcher needs just over 8 litres per minute so the 12 volt pump will not help as it seems to be rated 5 litres per minute

The Karcher K5 should work from a water butt without an additional pump......

How long is the hose between the butt and the PW? Needs to be as short as possible.

To get the best flow from your water butt to the pw, the shorter and fatter the pipe the better

Some useful reading on this topic

Please bear in mind that running a pressure washer on an insufficient water supply is really bad for the high pressure pump.

I'v got a K4 with that hose, you have to "prime" the hose. You need water in the hose to get the pressure washer started, I submerge it in the water butt first to fill it up.
