Tiger Diver, Just a heads up. If you plan on using 2" PVC pipe for a sleeve, it won't fit through a 2-1/4" hole. The outside diameter is 2-3/8"

Have you checked the voltage at the clock terminals? If you have a 120 V clock, the neutral wire may have problems before it gets to the timer.

Look at UBC 2320.8.4, IRC R502.10, or IBC 2308.8.3. All have similar language. The IRC seems the most conservative by specifically saying a single header. See R502.10 on this link http://www.cbs.state.or.us/bcd/boards/rsb/boardpack/07/100307/public_hearing/ch_05.pdf

If it is ABS drain pipe, it probably has a foam core. I never tried bending it. But, I suspect that the foam core could cause problems when bending.

I agree with Bob. Here are some more sources for information on additives. http://www.epa.gov/ORD/NRMRL/pubs/625r00008/fs1.pdf http://waterquality.cce.cornell.edu/septic.htm#chemicals

I would go to a real plumbing supply and get red brass nipples.

It looks like California is considering a more widespread use of PEX. Here is link to a notice that says they are going to prepare an Eniviromental Impact Report for the use of PEX. http://www.documents.dgs.ca.gov/bsc/NOP%20Final%2010.31.07.pdf The letter from San Diego is a little old and...

Lee, Some time when you are in an experimenting mood try this. Put a dab of primer on some PVC and a dab of acetone on a differnt spot. Wait a little bit but before the primer drys, scrape both pieces and see which is softer.

I never said that I liked the pipe attached to the subfloor. I would never do it because I have seen too many subfloors that have had another layer addded with long nails. I wished I was wearing a hardhat everytime I have climbed into an attic or crawl space that looked like a porcupine on a...

Construct30 The codes (both UPC & IPC) are concerned with pipe passing through framing members. Subflooring is not a framing memeber. The orignial picture doesn't show the pipe passing through the joists. What do you do with drains and vents inside walls? Run a steel plate from floor to...

The logic doesn't work. The relationship between flowrate and pressure loss is not linear. I do not know what process is used to develop the tables in the code. Two common ways of estimating pressure loss in pipes are the Hazen-Williams equation and the Darcy-Weisbach equation. You will find...

leejosepho, I don't understand how you can make any of those assumptions. The current edition of the Steel Construction Manual doesn't list a W8x8.5 the lightest W8 is 10 lbs and it is only 4 inches wide. There are several W shapes that are close to the stated dimensions, and the lightest of...

Most building codes require a steel strap over notches in top plates. So you could not install the box and still have it accessible with the strap. Here is a link to a strap that commonly covers these notches http://www.strongtie.com/products/connectors/RPS.html .

Why don't you call the manufactures of the equipment? They should be able to steer you in the right direction. By the way, it is Nationally Recognized Testing Laboratories. UL, FM, CSA, and NSF are a couple of the NRTLs.

Start at the gas cock where the gas pipe comes out of the floor. Work your way toward the heater. Those old valves are prone to leaking.
