The home is 6 yrs. old, no signs of fire, or significant water in the crawlspace. An addition was built on one end of the home not to long ago. Got to have been the cleanest crawlspace I have seen in a while.

The double 2" x 4" plates suppose to be joist supports? Marcel * * * ---

**Originally Posted By: Steven Brewster** **This post was automatically imported from our archived forum.** * * * Marcel, The span on the joist that are supported by the 4" x 4" are within normal span limits. I think they installed the bracing to prevent a bouncy floor. The roof is trussed so therefore the joist only support the load of the floor. As mentioned, there did not appear to be a significant moisture problem in the crawlspace, but we haven't had a good rain in several weeks. Will inquire if there is a disclosure statement by the seller. Thanks for the info. * * * ---

**Originally Posted By: dedwards** **This post was automatically imported from our archived forum.** * * * I know it isn’t the original question but I noticed a significant drop on one of the main Drain lines in the second photo that could cause some problems. I have to agree with the other posts. I too notice the rusted nail heads in the first photo and my first thoughts were they were using a paint with antifugal or a mildewicide additive to combat a potential mold problem. The blocks do show signs of moisture. * * * ---

What I thought was a double plate prop was in fact the illusion of the check crack in the 4" x 4" as you mentioned was used. I fail to comment on moisture of the block work, because I don't see block work. Supporting the joist mid-span only tells me that it was undersized and did not meet code to the L/360. The CMU with shims and shimming at the intermediate supports do not quite meet the standard of practice in floor framing construction. The rust that you see on the wood bridging that was added for lateral bracing and added component to the diaphragm of the floor assembly, was caused by painting the exposed framing members with a latex based paint. Does it every time. Moisture in the paint reacts with the metal like moisture does on any metal. The plumbing also annoys me to the fact that I guess this plumber did not believe in using plumbing wye's. A three inch waste should not dump at 90 degrees into the main, and all branch lines should intercept the main with the flow as the two inch branch shown dumping in a sanitary tee. I am sure some plumbers will correct me out there, but I am just talking off the cuff on this one. (Logic. ) Hopefully, you called this one out as you saw it and needs attention and recommendation of professional contractors. Marcel * * * ---

**Originally Posted By: Steven Brewster** **This post was automatically imported from our archived forum.** * * * Yes Marcel, I recommended all the above. This is the same house with the S-trap fixture drains. As mentioned in that post, many deficiencies for a 5 yr. old home. Amateur workmanship, incorrect fitting used on drainlines (sani t on back) etc. The interesting thing is I can't locate a code ref. for the nose diving drain pipe. Talked to several plumber friends of mine and they could not pin point a code ref. but said it was just understood rule of thumb that you don't do that. Seem to me the liquid would out run the solids. The span for the floor joist is more than adequate (2" x 10" 16" o.c. 13' span). Thanks, Steven * * * ---

Coming out of a residence and if the pipe size were to be increased to 6" then the slope could conceivably be reduced to 1/2% pitch. On a 4" sewer pipe to the street no less than 1% pitch is required. All internal sewer pipes and laterals must maintain 2% pitch. There is a controversy as to what is acceptable through Plumbing Inspectors, though, as they do not control the codes outside the house in this area. Having pitch in excess is and has always been thought of as too much pitch will get the liquids out and the solids tend to stay behind. Common sense and a little physics will prove this accurate.
