So about 3 months back now we bought one of these for our water fed pole. We were doing a job on a hotel with rather neglected windows - every pane was covered in dust and grime, and baked on bird crap was a problem with about 50% of the windows.
The part immediately failed, or may have been defective out of the box. The soap didn’t drain from the reservoir as we were told it would. Instead it was flooded with water and almost all the soap immediately shot through the line and down the side of the building. By the end of just 5 minutes the soap reservoir was heavily diluted - almost pure water with a tinge of green. It didn’t even seem to matter if the soap/rinse toggle was in one direction or another, the device was still doing the same thing.
We returned it. Next one, same problem. Once more. Same problem.
No, it’s not hooked up backwards.
No, we never took it apart.
Yes, we’re using Unger’s own brand of window cleaning solution.
I’d love to know if anyone else has had issues with this, and if so, how you managed to solve the problem.
Also, if you have other in-line dispensers that you can recommend, I’m sure it’s something we’ll run into again down the road, and I’d love to have a working solution for it.
