HI MARK

Sorry it took so long for me to answer but I never scrolled all the way on the 2nd page so I did not see your response. I attached a new line drawing below with the red line being my main drain line . It is 3" pvc and it is about 21 feet to the right of the new toilet location.

Thanks mark I will be home all weekend so my responses will be very quick .

Thanks again
Jeffrey

Hi Jeff...

Well, it took a bit, but here we go... ;)

You said your house didn't have a vent going through the roof. It needs a minimum of a 3" vent stack through the roof...all houses do.

I have drawn all this up with a 3" vent stack going up the wall behind the toilet and that 3" vent will penetrate the roof...should stick up 18"-24" above the roof. If you decide you don't want the 3" vent stack then I will draw this up again without it, but I highly recommend that you take the time to bring your house up to code at this time!

I have drawn up the vent for the 2 sinks as a 2" vent, it could be reduced to 1.5" if you are going with the 3" vent stack out the roof. Where the jacuzzi/shower vent connects with the sink vent should be increased to 2" and then connect into an INVERTED 3"x2" sanitary tee wye fitting in the 3" vent stack. All these vents will connect in the bathroom ceiling (drill joists) or you could run them upstairs and connect all up there. Remember here, that when you connect the vents into each other you need to INVERT the sanitary tee wye fitting.

Vents need to pitch at about 1/8" per foot of pipe back toward the drain so rain/snow water drain back to the drain by gravity. The vent stack should be supported at the base of the stack and a 3" dandy cleanout should be installed as indicated in the drawing (also called a 3" test tee).

All waste pipes need to be hung every 4 feet. A cleanout is chown at the main drain line as you change direction... be sure to install this as it is required.

Where you come from the basement to pick up the sinks use a 2" long sweep 90 degree elbow. Use a 2"x1.5" double sanitary tee wye fitting to pick up both sinks. Use regular 90s to stub out of the wall, but do NOT cement a pipe in the 90s to stick out of the wall... DRY FIT (just stick an 8" piece of pipe in each elbow) these pipes for now and later when installing finish you can remove these pipes and cut them down to the proper length! This is ABSOLUTELY required for pedestal sinks (we can discuss toward finish). A 2" dandy cleanout should be installed below the floor in the 2" drain for the sinks... you will appreciate it in the future should the sinks clog (not included in my drawings).

Finally, review all details as drawn and let me know if you have questions... OK?

Hello mark

This looks fantastic it looks really good . I can understand everything , well almost everything:). My only question is on the 3" drain line going to the toilet what do i put there to pick up the toilet ? a 3" ty to pick it up? Or a reg 3" t. I hope you understand by the way i'm asking. but as for now i am pretty confident . This looks GREAT. Oh 1 more thing should i pitch the drain pipes 1/8" per foot too like the vent pipes. Hey Mark I want to do something for you too for your kindness on helping me out .

Thanks again
Jeffrey

Slope the drain pipes at 1/4" per foot minimum.

Thanks mygirlsdad

Thanks again'

Hi Jeffrey:

Glad to help! I revised the drawing above a bit... included an end cleanout for the shower/jacuzzi... check it out.

As MGD pointed out, 1/4" per foot of pipe is code requirement (thanks MGD, meant to put that in my post).

Use a WYE fitting into a 3" elbow to pick up the toilet. Use only WYE FITTINGS on the drain pipes. Sanitary tees can be used on the vertical drains to pick up sinks... ;)

Sanitary tee fittings can be used on horizontal and vertical vent piping... just pay attention to inverting the fittings so water drains back from the vents to the drains.

Finally, we also need to discuss testing this system... needs to be filled with water to test all. I'll post on that next.

Hello Mark

I saw the updated sketch with the new revised vent for the jacuzzi and shower and also the cleanout there . I am in the process of making a material list so I cn pick up the stuff tomorrow.

Thanks again
Jeffrey
