RE: 800 square foot Northern Michigan Cottage
Hi Guys,
Preparing to rough in the DWV System in advance of the new Septic Field installation. The inadequate old DWV system has been removed and trashed. The septic installer can connect to either a 3" or 4" Sch. 40PVC DWV system. Wondering if in a small 2 bedroom cabin, considering a 1.6gallon flush toilet, the 4" would be better? Cost is not a big issue as this is a small cottage. Is there a measurable benefit? Please comment.
Also, when plumbing the toilet, is a "Wide-Sweep 90 Degree" fitting better than a "Closet Bend" directly below the toilet closet flange and vertical pipe?
When connecting the HORIZONTAL toilet line to the 3 or 4" main drain line (and this is all underneath the cottage which is built with a post and pier/joist set-up so the area is accessible), which fitting set up would make the toilet waste flow better: a "Y" fitting with 45 degree elbow combination, or a regular "Y" fitting, with a 45 degree fitting below the low heel vent 90 away from the "Y" fitting?
What is the best way to stabilize drain and vent pipes in the wall and reduce noises...metal or plastic plumber's tape, and would it be a good idea to wrap the vertical pvc pipes in a gasket material before strapping? Is using wooden wedges a good or bad idea? I realize that expansion and contraction are issues. Should one use the aerosal "Great Stuff" foam fireblock, or is that just for where the vent pipes penetrate up through the top plate.
the cabin is not heated in the cold Michigan winters if that matters. Supply pipes blown out of course. What would you do about winterizing the 40,000 gr water softener?
Appreciate the feedback.
