The Bastion 15 is manufactured by Flow Techniques of West Sussex, a subsidiary of Drivall. It’s a smart, tidy-looking sprayer and is extremely lightweight. As well as being brightly coloured, the tank of this sprayer is slightly opaque. Without a doubt it is robust, but it is also possible to see the level of liquid.
The 115mm diameter hole also helps the filling of this sprayer and the base is particularly stable. Although the lids for filling and piston access are the same, confusion should be avoided as the piston chamber lid is labelled For Service Only. But our tester is not happy about the basket filter.
“It is quite deep but only the base is mesh — the sides are solid. You’ll have to be careful filling this one or you could easily get splashback,” he says.
The eight-page manual is printed clearly and contains the bare information to use the sprayer. There is a useful “Do’s and Don’ts” section, but the exploded diagram is something of a riddle.
Nevertheless, we find the operating lever is easy to fit — either left or right — and the lance and trigger simply screw together. O-rings are employed throughout so connections should be watertight. Although it is of a reasonable length in its basic form, the lance will extend. There should be no reason to stoop with this unit.
This sprayer does have a pressure limiter lever, adjustable from one to three bars, situated between the lids. All the testers are surprised to see the sprayer also has a pressure gauge. Fitted onto the trigger, our tester questions how easy it is to read the gauge. “The gauge is difficult to read accurately when you point the lance at the ground,” he says.
The Bastion is comfortable to use, although we would like a little more padding on the shoulder straps.
“This is short on comfort features but it is extremely lightweight,” admits one observer. “The basket filter is the shallowest we’ve seen and lacks mesh sides.”
“It may be of use to someone with small and infrequent spraying jobs,” says the tester.
Three sheets of paper detail instructions in quaint English, witness “Both pregnant women and children should be excluded from the use of the sprayer” and “Do not make too much effort”.
