I was disappointed with the pressure of a tub and shower that were plumbed with 1/2 supply lines (2nd floor). Could be low pressure from the street, but I want to replace with 5/8. Plus, I'd like to have 2 back to back showers, one inside and one outside. So, I had intended to bring a 1 supply to both, then branch up to valves and shower head with 5/8. Finally, I thought pressure from the street was typically 55 to 70 psi and I am concerned if pvc can take that.Any thoughts?
11.2c If the springs you installed are too weak, and you wind the springs the correct number of turns, the door will be heavy at the floor, and it will not stay open half way, but it will stay open if raised completely. If tension is added to the torsion springs to lighten the garage door and to get it stay open half way, the door will be harder to close; openers often damage the new steel garage doors when they are too hard to close.
If you've installed a replacement door or two around your home, it seems pretty simple -- all it takes is tightening a couple of screws and you're done. Installing the largest door in your house, however, is not quite so simple. Garage door installation, whether manual or automatic, can be difficult and dangerous. Manual garage door installation is much easier than automatic garage door installation, but the one you choose generally depends on what kind of door you have.

10.5 If the spring comes loose from the cone at about 6 turns, you are probably winding the spring backward because the springs are on the wrong sides. Switch the springs. Otherwise, after winding the torsion springs, you will need to stretch the springs and secure the winding cone. First, mark the shaft 1/4" beyond the winding cone with tape or with a file. We stretch the springs because the shaft floats horizontally between the flexible end bearing plates as the garage door operates. Although this may be as little as 1/4" the binding of the coils as the door closes often keeps the door from closing completely, especially when the springs and bearings are dry and need lubrication.
9.9 Go to the other side of the garage door and insert the end of the cable into the drum. Rotate the drum until the cable is tight. Slide the drum against the bearing and push the shaft to the right. The marks should line up. If they don't, figure out why and correct the problem. It could be a stuck cable, the garage floor may have shifted, or the vertical angle that helps support the bearing plate may have loosened and shifted. Many garage doors have been installed with a gap between a drum and a bearing plate. The cable drums should always be flush against the race of the bearings. https://www.youtube.com/attribution_link?a=Z_eZc-kh40c&u=watch?v=XXXXXX&feature=share
A standard double garage door is 7 ft. high by 16 ft. wide. Standard single doors are 7 ft. high by 8 or 9 ft. wide. Because the doors are so large, few home centers and only some garage door stores keep many doors in stock, so expect to order one instead of buying it off the shelf. Garage doors are available in wood, fiberglass and steel. Steel doors, like ours, are light, maintenance-free, affordable, readily available, and have an insulating value as high as R-19.
