Thank you for your thoughts and ideas Old Man Roger. They do help.

I believe capping the inlets is pretty much what I did with the valves. Open to operate. Close to cap that inlet/outlet. Valve B isolates the rest of the system. It still leaks down when valve B is closed. Fluid has to be getting past the piston. There's no where else for it to go. Closing...

Obviously, American Locomotive is correct. The drift stops because the volume around the rod is much smaller than on the under side of the piston. With valve A closed, the fluid below the piston simply has no where to go. That situation has the same affect on drift (it stops), but with an...

It's always possible there are two leaks, but it's unlikely. I cleaned and inspected the power unit components (check valves, etc.). They all appear to be OK. Also, there was no decrease in drift speed when I isolated the entire power unit using valve B. Oddly, the speed did change dramatically...

I have a hydraulic lift that raises normally, but rapidly drifts down. While isolating the problem, I ran into behavior I can't explain. I'm hoping someone can provide some of that good learnin'. The hydraulic diagram is attached. I removed, cleaned and inspected the components in the power...

Thank you Walter. I am a bit confused by your explanation though. An integral J channel is just a slot that is pre-formed in the window frame. The window has to be placed at a wall panel seam. The wall panel(s) is notch from the side, "smaller" than the window frame. So the panel slides...

This is a new construction (next month), red iron building. The windows will be framed with C channel and J channel trim is available. I'll be using new construction vinyl windows, and I'm unsure what style to buy. What type of window is easier to seal and keep sealed long term; those with an...
