Copper or CPVC to replace copper pipes?
Comments (8)"Is it necessary, or a good idea to replace the areas of the house that were not included in the remodel, since the house is 25 years old since it is M copper?" Yes, do a total replacement, as the copper has reached it expected life expectancy. CPVC is widely used in mobil homes due to it's flexibility and lack of out-gassing at the glue joints. "Also, the plumber wants to use several island vents, including one in a bathroom. He doesn't want to go through the roof." You need to have a short and serious chat with your contractor about quality of workmanship, because this is BS. "And yes I think this is all about the general contractor saving money, my husband is afraid that if we push him too hard about the pipes he will charge us more on change orders/items that he has completed, but will not give us a price on." In many states all change orders are required in the business and professional code, to be fully priced upon presentation for signature. But, why would you sign an authorization to proceed, without knowing what it cost? "We ask him how much adding or changing something will be, instead of telling us he just builds it without giving a price or change order. We have asked him several times to write it up, but he does not, Its really irritating and yes my contract states that he must give us the change order in witting, before he changes anything." If you know an attny. better yet where he lives, don't wait until monday, race over to his house and break in....See Moresplice aluminum and copper
Comments (29)Wow.. this whole thing sounds confusing... But the code is like the bible. Every Inspector has their on interpretation of the code book. The inspector of this county says its ok to do it this way and in the next county this inspector disapprove of it and want you to do it his way. Even though the code says you can do it this way but being that the inspector has the last say so.. He wants it done his way. Some states that I know of still uses the 2000 code book and some still uses the 2005 and some are now beginning to use 2008. Its all depends on that State's Head Electrical Inspector of which code book they are using. Now, I can explain why things are the way there are. Now. remember this, even though there is a 100A sub feed panel but it is only getting 50amps from main main panel because its on a 50a breaker. Head you used metal Ridget conduit leading to the sub feed panel back to the metal junction box in the crawl. You need not worry about needing the ground rod because the metal box is bound by the panel and the connector of the metal conduit bonds the junction box. In sub feed panel you would have to separate the ground and neutrals if it was done that way. # 6 aluminum is rated for 50 amps. #6 copper is rated for 55 amps now the amps varies depending on the temperature rating of your wire. Now, here are one reason why there should be 4 wires at a sub feed panel. The ground wire is use as an escape way for wasted energy to flow back to ground ( the earth) If ever notice that your lights are extremely bright an not normal or your power tool is running too fast, its because there is no ground. No where for the access energy to escape so it makes your tools and light bulbs run abnormal. The reason why you use the rubber tape is because over a period of time the joints generate heat, standard black tape will melt and you will have expose hots touching neutrals and grounds together causing a fire. So, the heavy duty rubber is tolerant to the high heat. Then you cover the rubber with standard electric tape to keep the rubber from coming undone. The bolt that you used sounds like a different type of split bolt. Same concept but design differently. I'm sure the the entire bolt was all metal. Ok you are right the aluminum wire is not touching the copper wire. If I'm right that zinc metal piece that separate the two metal is also a conductor. Over a period of time aluminum does corrode much faster than copper. Corroded aluminum makes a bad connection which also creates sparks and then fire. The gel is used to keep the aluminum cool and extend its life a little longer than normal. Older homes catch fire because of aluminum wireing that gets over heated and catch fire in the walls. Ok.. enough for now......See MoreAluminum wiring
Comments (6)> If I get this house, I will be taking some type of action to > help reduce the possibility of a fire hazard (I'm paranoid). Proper workmanship in any house means lights do not dim even when a laser printer or window air conditioner powers. Many ignore dimming because only copper wire was used - very forgiving. Aluminum wire is not forgiving. Dimming (due to many workmanship defects or the cold creep) indicates a poor connection. The same poor connections in copper are, unfortunately, a fire hazard when using aluminum. The house has existed for 40 years without problems. If extra care is always exercised, then you should not have problems. Care includes actively finding and eliminating any poor workmanship indicated by dimming incandescent bulbs. In the famous Beverly Hills Supper Club fire that killed over 100, they routinely ignored dimming lights. Most just say that is normal because a house did not burn down. Even a window air conditioner. toaster, or laser printer do not cause dimming when wires are properly bonded. For aluminum, that means more than an anti-oxidizer inside wire nuts. It means aluminum wires twisted together so as to stay together BEFORE a wire nut is screwed on. An example of minimally acceptable workmanship for aluminum wires that many should and fail to do for copper....See MoreAluminum wiring
Comments (18)I appreciate everyone's comments. There was a lot of other factors that went into us deciding to walk away from this house deal. In the beginning the sellers wanted 229 and while we hesitant to offer that much due to comps not matching up, we were willing as long as it matched up with appraisal since my parents are buying with VA loan. Unfortunately it came back at 215, and after some back and forths with us losing all the extras we had asked for, 3% back, warranty, 1.5k repair costs if something came up in inspections... which is understandable since I'm sure they felt they were out 14k, we came to the agreement of buying at appraisal. Inspection came around and my realtor did warn me the ones we hired were really detail oriented, a lot of things popped up. Old house, again, we expected things to have to need some fixing. 9 pages of issues and the only thing we really cared about them taking care of was the one thing that would prevent us from being able to buy it, aluminum wiring that the insurances down here won't cover. We called 3 different agency reps who went thru all their contacts. We were told pretty much nobody would insure the house except 2 companies, one offered 1.9k/yr another 2.9k/y. But the wiring would have to be fixed BEFORE they would insure it...which in my mind means if we did purchase the house as is (which I don't know if it'd be possible since the loan requires insurance?) it wouldn't be insured until we fixed it, so if something happened between that time to the house.... well we just weren't willing to take the chance. But we found another cute lake house to view tomorrow, cross your fingers for us that it matches our needs :)...See Morebtharmy
