This was my first version of my pressurized transfer pump / device. I had a clear hose installed and you had to blow air in the inlet side.
The job really blew…. I thought I would be able to siphon out the chemical. But the matter what it seemed like if would not start a siphon.
This would work fine but I wanted to try it air driven. Plus I ened up breaking 1/2 the fittings trying to get it to start a siphon.
