That won't work will it?
If you can reach the trigger, you could reach the UPVC...

Long fingers?

You lock the trigger down before you extend the pole

Diluted TFR in a 5L Pressure sprayer. Aquadapter on my pole. Pump up sprayer to full pressure. Connect sprayer to pole hose. Quick spray with TFR. Quick disconnect sprayer and reconnect water agitate TFR on whatever surface put water back on and the TFR in the hose will rapidly dilute and dissipate.. Works a treat for me.. Simple as a big simple thing.

Could you not put the trigger at the bottom?
What you've done is exactly what I was hoping to do...

I did the same with an old pole and a 5 ltr pump up sprayer, though I removed the trigger from the lance fixed to bottom of pole and modified the nozzle to fit the pole hose and attached it to the gooseneck. Worked well but like to keep kit to a minimum in my van. So now I just fill the backpack and spray on with fan jets ( I have both fan and pencil fitted and swop between them to suit the job )

.     I guess you could but it was just a quick Sunday project and to be honest I don't really think it would be worth the effort
