    This is my setup. Please keep in mind that this was a repair not an install. The customer did not want me to move the cond unit away from the wall.

    Looking into my notes on everything I have researched. Looks like I contacted NorthWay last year and purchased a 6" hose. I just walked out in my garage and looked at it. Still in good shape, tough part is the replacement O-Rings are different than anything I can get without special ordering a kit from Northway.....unique brand called, CBI.

    Here are some pictures from today. The stainless hoses are a bit more flexible than the black evac hoses I had been using.

    I can't bring myself to throw away a vintage nameplate or thermostat. The techs all know to bring vintage branded tstats metal logos etc to me! I have the Brady bunch Lennox chrome tstat that was going down the stairs of their house ! Also an old carrier nameplatevfrom an early 1950s gas fired heat packaged with water cooled ac built in. Had a water in valve and a floor drain with city water!

    "NOTE: There is a mesh screen in the YJ brand of pumps to prevent debris entering the rotaries. Make good practice to remove and clean screen annually. It is fine mesh and clogs fairly often."

    Where is this screen located ?

    Greetings everyone, a question comes to mind about these hoses and evacuation in general. Slctech, I see the hose data you listed indicates those hoses are good to 28.--- inhg. I was under the impression that evacuation of systems should be in the 250-500 micron range generally to ensure good dehydration. Here is my question for you. If the hose is rated 28.--inhg and seeing that good dehydration does not happen until the system is between 29 and 30 inhg, howdo you know your inner hose is not collapsing under this greater vacuum?
    I like your approach here its just I have seen hoses collapse and thereby give a false reading.

    Just wanted to say, nothing like thinking outside the box, making something work better, easier, cheaper but safe still. I have always tried to do things like this and mainly suceeded. Hard part is to convince some people it's worthwhile !

    I had a reputation for this kind of thinking at a place I worked for 20 years. They could usually tell if a project was mine by the pile of drill chips beside it. Or the glue containers. I fixed one system despite being told not to, and the other techs were setting up to take it on a field job and I gathered that they told the bosses that whatever I'd done made all the difference in the world for accuracy and ease of setup. Never got any **** for doing it and later was asked to fix all the other units the same. Actually got a mention in some project report about coming up with unique solutions to problems, but that time I was in on the brainstorming of a serious problem, but others came up with the solution, we just liked it and did it.
