comment Repair tub liner with water trapped beneath
While Ecnerwal's flippant attitude may be off putting, it really is the proper approach to your problem. IMO, it is not possible to achieve what you want. To remove the water and properly seal the liner would require complete removal and re-installation. If you're going to go through that much, you are truly much better off replacing the tub. Especially if you do not want the same thing to eventually happen again.

comment What should I use to repair plaster in a bathroom?
You need to remove all plaster that is moisture damaged. By the time that is done, it is well beyond a spackle patch job, it requires re-plastering. Dry mix would work of course, though I would expect that pre-mixed patching plaster would be available in most areas. Damage is because water got past the paint film. Any installation that prevents water ingress should be fine as long as the paint is maintained.

comment Preserving cracked concrete
You do want to prevent water entry. Caulk any cracks big enough to accept caulk. Any smaller (i.e. "hairline") cracks should be able to be bridged with latex paint alone. If there's any gaps too big to caulk fill them with more rendering.

comment Is it stupid to replace redwood siding with Hardi board or LP SmartSide?
Sounds more like an emotional reaction from the painter rather than any practical advice. Or maybe he was afraid it would be replaced with an inferior wood product, which really would be a shame. Cement board is not an inferior product!

comment Dormers with ridge vents lower than main ridgeline
It's difficult to say for sure, but the smaller the difference in ridge heights in proportion to overall heights, the less likely there will be any issues with ridge intake. IMO you will not have any issues from the sound of things.

comment Noticed low-level damp issues in kitchen walls, what's my best course of action?
The best course is to identify and stop the source of moisture. Then you needn't do anything special with the plaster.

comment How do I increase my water pressure to my underground sprinklers?
Is the replacement valve the exact same design? Some valves are more restrictive than others. It could also be debris and/or dirt has gotten into the system.

comment How do you remove a wire from a push-in fitting when there is no release opening?
The side slots are supposed to release the two wires immediately above by pushing in with a small screwdriver. For some reason these release mechanisms do not always work that well. If they do not seem to work, cutting the wire or crushing the outlet is the best options. When using binding posts, there should be metal on both sides of the wire. It's OK to have wire under the screw head only, but some devices do have a clamping plate, in which case there will be another metal base below that.

comment Utility Tray - how to calculate loads on beams
The basic structural theories involved take up entire textbooks. There's also a fair amount of judgement involved with something like this, such as how much dynamic load factor to apply. Judgement requires experience. You could probably do just as well by looking at similar commercially available structures and doing something similar.

comment Plumbing alteration has created vacuum in upstairs toilets
Well, it was a vent, though someone may have very well drained into it though they shouldn't have. Or it was acting as a vent. It's really semantics in a way, it's certainly tied into the vent system either way. If you can't change the basement, you'll need to locate the obstruction above the toilets to solve this. The basement toilet is not properly vented, but I suspect it should continue to work OK.

comment What can I do if the sink tailpiece is too close to the wall?
Right, as Tester101 illustrated. Even if the wall outlet occurs exactly behind the tailpiece, there should be just enough room to install a 45 ell to take the P-tap outlet out of line of the tailpiece and enabling the suggested twisting around of the trap's U-bend.

comment Can I replace 3-way switches with 4-way switches?
@bib - Thank you! Much better. I reorganized rather than replaced because I thought it may be useful for some to see how each type is normally used and how the functionality is related.

comment Need help wiring switches with several wires
Cool! Then you can switch from the main box OR the living room box but not both. You abandon the lines between light and undesired switch location, then connect the light and switch as in comintern's first illustration.

comment Need help wiring switches with several wires
You still need another conductor unless for some reason the living room is not getting power from the main box. Try disconnecting one of the wires between the two. If the living room still works, there is a solution. If not, you need another conductor.
