I have just finished putting together a long reach sprayer, so I can get tfr into those high and hard to get to areas.
I chopped up a standard sprayer and fitted a long hose. I attached the spray end to the end of an old pole, and the loose end runs to the trigger. The other end of the trigger runs to the bottle via an easysnap connector so I can isolate the bottle.
Hopefully It will do the job tomorrow. The pole will have about 12ft reach.
What would be really handy is a quick on/quick off clip that attaches the spray end to any wfp pole.
Looks like I will be back in the shed at the weekend.
