My 16lt backpack sprayer has sprayed about 100lt in the 12 months since purchased and the pressure switch will not turn off between spray spots can this switch be replaced PLEASE REPLY ASAP
Cheers,

If the switch is not turning off, then it is likely that you need to adjust the pressure adjustment screw slightly clockwise until it does. The switch itself is fairly reliable but the pressure sensi...
Read moreng mechanism sometimes gets jammed. Another reason for the pump not turning off is low battery voltage which means the pump doesn't generate enough pressure to switch off.
Why does it only work when it’s connected to the charger but doesn’t when it’s not
Where does fuse go in the 16litre backpack sprayer
There is a fuse in the battery compartment section, but you will need to remove the compartment from the sprayer. It uses a 3AG automotive type fuse, but you may need to use a different type of fuse holder as it is flimsy

Does Silva have an extension for the wand or maybe a longer one for spraying up high
I have had my 16 l battery knapsack for about 5 years, I'll never go back to the hand pump type. My pump has developed a leaking seal. Can I get an exploded diagram of the RS775-3764 pump. Can I get replacement gaskets or do I have to replace the whole pump? Also, do you make an ergonomic harness for this model? It desperately needs a waist strap and more padding on the shoulders.
Hi Sam. I can't answer your questions as I am not associated with this company. I only bought their product a couple of years ago and so far am very happy with it.
Does it have an extension wand?
According to the manual, the backpack sprayer is equipped with a "Poly trigger gun with 550mm lance and adjustable nozzle". You can work out the reach of this by adding on the length of your arm. I'm ...

I have mine on a sack trolley and red it to be abut longer something that they make might fit on
