thanks for the welcome biggrpro and ndg1I have a company called DCH Management,LLC , my site is www.investwithdch.com , I am primarily into single family rentals (I prefer Sec 8 tenants) , I am also starting a "flip" and in Phase 1 of drawing up plans for a small 16 unit sec 8 housing. just drawing up the plans is exhausting.

There would no way to even guess how much it would cost without knowing exactly where the splits are in your pipes to the individual units.

you need to exhaust your learning possibilties, pre-mentor.

There are some other things, pvc drain pipe from kitchen is broken from the sink to the sewer line, replace the gas water heater with a electric, a couple broke windows, storm door.

I would call a very experienced plumber.My first thoughts are that water could be infiltrating into a pipe with root damage.

Splitting off to a JB that's intended for a hard wired wall hung microwave or an exhaust fan would be a violation, USBs not sure.I spoke to one inspector and his reaction was he would overlook it since its not hurting anything but he might question it if he sees a dedicated one, such as a receptacle with nothing else but 4 USBs.Anyways, one or two local inspector's opinions may not mean much.

Here the stove company would put the insert in and the propane company has to add the piping.

I also just found out that the exhaust fans are sparking and the insulation shows signs that it is shorting out.

Hopefully its real and not some pipe dream.

I couldnt exactly prove it, so i changed the toilet to a one peice toilet and instructed the tenant how to sit on the bowl.If the wax seal under the toilet was broken then I imagine any flushed water still flow down the pipe and then worst case partially discharge to the surrounding floor joist area or pool in the bathroom.
