8.5 Inspect the bearing. Lube it with motor oil, spray lithium, or spray lubriplate grease. Do not use WD-40. If the shaft is worn and the bearing is seized and you can't free it, replace the bearing. Or, if you have bearings labeled "ADH" we recommend replacing them. I find very few other bearings that need to be replaced. However, if you do need to replace the bearing and you do not have a new one, you can replace it at a later date. You'll find a quick way to do this at our End Bearing Plate Replacement instruction page.
All measurements should be in feet and inches. Step 1, measure across the existing door or desired space for the width, then up and down for the height. The rough opening of your space should be the same size as the door. Step 2, measure the sideroom, which is the space beside your door. Measure the width of the left side, and then the width of the right side. Step 3, measure the space above the door, which is called the headroom. Measure the height of the distance between the top of the door opening and the ceiling. Step 4, measure the ceiling, which is called the backroom. You’ll need to measure the distance of the garage door opening toward the back wall of your garage. You should have 6 total measurements in all once you’ve finished measuring the space. Keep in mind that having an automatic garage door opener installed might call for additional backroom or ceiling space.
A new garage door can add serious curb appeal, not to mention myriad home safety benefits. The cost of a new garage door will vary based on the type of garage door you want and the materials it will be made of. You can purchase a new garage door and have the pros install it for you, but proceed with caution as many installers won’t guarantee their labor if you didn’t purchase the garage door through their company. A new door (without installation) may cost anywhere from $200 to $4,000 or more, depending on size, brand and materials. Here are some examples of average new garage door costs, including installation:  

Both types of springs are _loaded_, or under tension, when the door is closed. This gives them stored energy to help lift the door as it's being opened. When the door is all the way up, the springs are relaxed, or relatively so—they still may be under some tension. The mechanical difference between extension and torsion springs is that extension springs are loaded by stretching, or elongating, while torsion springs are loaded by twisting, creating torque.
	10.13 Slowly pull down on the winding bar until the garage door rises 3" and the roller hits the vise grip on the track. The door will usually drop back down and raise the bar. If it doesn't, lift the end of the bar until the door closes. If the door comes up by itself when you hold the bar lightly, the springs are either over wound or they are too strong. You may need to remove 1/4 to 1/2 turns from the springs. If the door comes up on its own, you either have to many turns on the springs or you have the wrong springs. This can be very dangerous. We recommend getting professional help. Removing the winding bar could cause the garage door to knock you off the ladder.

Lower the door and dismantle it by removing the hardware. Lower a double door by recruiting at least two helpers to help with the weight, and place a 2×4 block under the door to prevent smashing a foot or finger when it’s lowered. Remove the sections one at a time by disconnecting the rollers and brackets. If you have windows, tape them to help control flying shards if they break. Then remove the old roller tracks and remaining hardware.

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?
