HOZELOCK - Knapsack Pression Sprayer Pulsar Plus 12L Comfort : Ideal for Large-areas, Comfortable, Easy Pumping Action, Reinforced and Adjustable Carry Straps, 60cm Aluminium Lance [4712B0000]

As a 5'3 woman i would struggle with a larger capacity than this! It is well designed and ergonomically shaped. May have to shorten the pressurising arm, but otherwise it is spot on! Found the loose fit of the filter inside the filling port a bit of a puzzle, since hozelock fittings usually snap into place. Odd...and could tip during filling, which would make it pointless. Make sure you push pipe right into wand when you put it all together or it will keep falling off under pressure. Also, tighten filling cap as much as possible or you will get a bath when you put back-pack on! Did have to shorten pump handle as i found the arm too long. Simple job with hacksaw, drill and self-tapping screw.

Before this I had a smaller hand pump type which I had to keep refilling. This unit is so superior and I only have to fill it once. The nozzle adjustment means I can spray a larger area so it’s much quicker as well. Very pleased.

We put it together without any problems and it has worked well.

Feels like a good product, however one of the parts had arrived to me pre assembled where the instructions would make me believe it shouldn't have.Unfortunately this part arrived poorly assembled with a part screwed on at an angle which had caused cross threading in an area where chemical would needed to flow through.I did not try the product in case it invalidated the return process.I returned the item and I've ordered from elsewhere as I'm still convinced this item is the sprayer I want, provided I recieve an un damaged item from my new retailer.
