Rear discharge toilet in the basement

We are needing a toilet in the basement and we have the stack available in the laundry room. Can we use the rear discharge toilet and go into this??

 

Are you talking about a pump up toilet system like a Liberty or Sani-flow? Its recommended to tie into a 3 or 4 in line which
you have. They also need to be vented.

 

Hi Tom,

No, I am talking about a rear discharge toilet and have it tied into this stack.

Have you looked into a rear discharge toilet. They have to go into a carriage that ties into the main line. It could
probably be done but that clean out wye is in the way and would have to be rearranged. A pump up toilet system would be ideal in your situation.

 

Just trying to save some money here, the pump systems are near 1000 bucks

 

yes you can buy a floor mount/ rear discharge terlet, that does not require an expensive carrier

but...the terlet itself is aroud $300.00....and thats a cheap one



All of this will have to be removed and reconfigured



or a platform built.

 

OK, Reconfigured how??

 

it has to move up, so a tee can go beneath it at 4'' center aff

 

crane makes them and eljer did make them...I installed one in my house....worked fine use plywood between the studs so you have something to anchor your flange to

 

Could I use a double "Y" where the lower "Y" is??

Chuck

 

no.
well....yes you can. but the flange will not be 4'' off the floor

what you have to do is easy,
shorten the 2 pipes at the top the same as the take out on the tee
cut the bottom 1 1/2'' off the floor

set that section aside

install the tee

clue the removed section into the top of the tee

reconnect the pipes using 1 --each proflex couplings
model numbers. 4''--3000 43
2''---3000 22

pop the top on a cold beer.

 

WOW, that does look easy, Now how do I approach the vent??

 

not required, a terlet fills its trap after flushing

 

Sorry, but how high does the toilet flange have to be above the floor to have enough room for a 3" bend and then connect up with the san. tee centerline, which looks like would be a minimum of 4 1/4" above the floor?

Not sure what that 4" dimension represents.

 

I read that hooked up like this , when a terlet upstairs flushed, it will suck the water out of the downstairs one.

 

the flange is in the wall, it is not on the floor

 

Sorry ...that was my problem. Thought it was going to be raised on a platform.

 

no it will not

for that to happen the whole system would have to be no-vented
and the terlet upstairs would cause a suction
the main stack. is vented via the washing machine vent, it will not back siphon

 

Hmmmm...Would it be reasonable to assume it won't be that existing concrete block wall?
Does OP plan on building a new wall for the purpose of using a wall mounted toilet? I suppose that's obvious. I retract the question.

 

he really does not need a wall, the terlet bolts to the floor
so their is no strain on the plumbing.
for sanitary reasons i would build a wall
