The sink is just to the left and the shower just to the right. When you walk into the bathroom door, the toilet is straight ahead.
I will try to get a diagram (but I am electronically challenged) but for the meantime I will try to explain with words-it might work since it is a very simply layout. The toilet will sit only about 16-20 inches in front of the barrel. The only reason I am using the 4" is because the toilet will be 4" to start and it is such a short run I didnt see the value in reducing. So, I figured it's better to have it all plumbed properly for that reason-as well as safety. Next year, I plan on doing a rear dormer (I live in an undormered cape) and when the time comes I will need that plumbing inspected. I do not plan on getting this inspected but I want to do it so it would pass an inspection.
SEWAGE EJECTOR PUMP INSTALLATION DIAGRAM CODE
All of the wet venting I see has a wye where the fitting is turned up.Īre you sure about that? My state's code still allows it in the 2010 codebook: My question is, can the shower or sink act as a wet vent for this toilet? The thing that has me unsure is that the wye will be laying flat. So, there is very little room between the toilet and the barrel. Then, this wye will go right into the sewage ejector barrel. This double wye will be laying flat, so that the two 2" connections are flat on the ground. I plan on having the sink and shower on either side of the toilet, and they will drain into the wye. I have 4" combination wye with two 2" connections (a 4x4x2x2 I think it might be called?) The toilet flange will only be about 16-20 inches from the input to the sewage barrel, which will be on the opposite side of the interior wall the fixtures are on. The bathroom will have a toilet, a sink, and a shower all next to each other in a line, the toilet in the center. Although I will have very little room to do it. I understand that I need to vent each fixture before it gets to the sewage barrel. My space is limited so I dont have much room for the piping. I am putting a bathroom in my basement and will be using a sewage ejector. Question #4: Once this is laid down, do I just put concrete right over it again-it will run, partially, across my bathroom floor and I plan to tile over it. To run the line from the shower to the basin, I need to dig a trench. Question #3: Is he correct, can I add the alarm seperately? My plumbing supply place doesnt sell them but the guy said I can buy one elsewhere and just add it in myself? To do this, I need more holes in the top of the basin, right? I'd also like to add one of the alarms that tell me the water is high in the basin. Question #2: Do I just insert the 4" PVC into this, letting it protrude into the inside of the basin a couple of inches, and that is it? Does that make a tight enough connection to stop oders?
It is a Little Giant and the 4" inlet has a rubber grommet. This way the front hole can be only the toilet and it's vent on one fitting. He knew exactly what I was looking to do and helped me lay out the fittings.Ī) use a different fitting, one with two incoming and a vent on top.ī) utilize the second hole that is on the back of the basin for the sink and shower. If I do need to vent it, is a fitting made that would be like a triple cross-tee?- 4" run and 2" arms on left, right and top? If so, I'm not sure why the guy at the plumbing place wouldnt have suggested this. These two can easily be vented as they will be 4 or 5 feet from the basin, so there is plenty of opportunity to vent them.īut the toilet is so close that I can't fit another fitting between it and the basin.īased on the close distance, is it possible that I don't need to vent this toilet? That the close distance to the basin would be the equivalent of a direct vent? The two 2" parts of the cross-tee will be for the sink (reduced to 1.5") and shower. Then another short length of 4" PVC to go into the basin. Then a 4" piece with two 2" sanitary tees (I believe it is called a cross-tee). Then a small piece of 4" PVC to act as a close nipple. The toilet flange will connect to a 4" elbow. So, distance from the center of the toilet flange to the basin input hole will be about 16-20 inches. The way I am laying this out, the toilet will be right in front of the basin (the basin will be on the opposite side of the interior wall where the toilet is going to be). But for the toilet, the problem I am facing is that I dont have much room-unless I change my layout. I have read that each fixture needs to be vented before going into the basin. The pump/basin will handle the following fixtures: I am adding bathroom to basement and will be using a sewage ejector pump and 30 gallon basin.
