How much does a shurflo back pack hold? Some sites say 16 litres and some 18 litres but according to the spec they hold 4 US gallons which is 15 litres! Who is right?

I got the 4 US gallons from the Shurflo website so it's 15 litres then........or is it!

Is there such a thing as an 18 litre backpack then as I'm sure one of the cleaning suppliers is advertising one?

Yup it's marked to 16 litres but you can get a couple more in to the very top.

yeah id agree marked to 16, but can take 18-18.5 if you fill it right up

but you will only get 17 to work with, about a litre stays at the bottom below the hose where it cant be pumped out
