I've discovered a pretty severe kink in the hose leading into my Shurflo Revolution 4008. It's near the pump, between it and the water storage tank, and I suspect it's restricting my water flow because the hose is quite flattened out. So I plan to install an elbow at that point. Question is, if I cut the hose to effect the repair, will water drain out, and keep draining under my kitchen cabinets, until the fresh water tank is empty? Do I need to empty out the entire system before I begin work?

Unless the opening is above the water level seems to me water will flow. Ever see how a water level works Vs a bubble level? Water will seek its level point.

The pump has a check valve so water cannot flow backwards through it and fill the tank when your connected to city water. So I don't think that will be a problem.That is if I understand your question, which I'm not sure I do. :)

Is your water tank below the floor? If the tank is below the floor you should be fine. If the tank is up above the floor, drain everything before taking it apart.

I don't know how bad that kink is. We drain our tank by shutting off the spiqot and running off the pump for a few days. May not work for you if the kink is bad.
