Sanitary T In Attic

I see situations around like this sometimes.

Sanitary t in attic.

During the attic sanitation and decontamination process you will first want to perform a thorough deep cleaning. Still it s a good idea to spray the flashing area on your roof with a garden hose. Or in many cases it can tee into the home s existing venting system. There are 3 vents in one area and 2 in another.

If you have no other vents in the house and this is the only vent going through the roof the last t the upper most one before exiting the roof needs to be a 3 x 2 x 2 t and not a 2 with an increaser reducer after it. Another important thing about plumbing vents. You ll probably have to go to a plumbing supply store to find the 3 in to 4 in. Then check the attic to make sure there are no other leaks.

The best way to get rid of rats and mice is to use the classic wooden snap traps or bait traps. Because they need water daily they tend to nest where water is readily accessible. The use of tec vent in return air plenums shall be allowed only in engineered drainage systems designed by a design professional and approved by the local authority. Studor aavs installed in attic area must be located a minimum of six 6 inches above the ceiling insulation.

Only two plumbing set ups could require sewer pipes in the attic. In the ipc use a 1 5 sanitary tee upside down or in the upc use a 2 x2 x1 5 san tee upside down to make this connection. The first would be a bathroom or kitchen in that part of the house and the other would be a pressurized drain system with pipes. Then this vent can terminate through the roof all on its own.

I have a customer that we are doing some work in the attic for and i noticed yesterday that the plumbing is vented up into the attic phew and not thru the roof. Possums and raccoons leave behind much more waste than rats. Roof rats aka black rats often build nests in attics. This will help remove dust and dirt which has inevitably collected over the years.
