Basement Bathroom Input Requested

guyute65045

Hello all, I am an excavating contractor/septic designer. I have a few questions about putting a basement bathroom in my house and am looking for some feedback on set ups.

Set up one, the liberty up flushing toilet the $1500 model that is supposed to handle the toilet, tub, and sink. not sure if I believe the pump will handle that much flow, but I have no practical experience with the product. The only feedback I have gotten is that the pump is loud and cycles often.

Set up two, a Zoeller 35 gallon basin/pump set up. I haven't really looked at the specs on this one, but my precast supplier says it is the way to go for a basement bathroom, can even be buried outside with a riser. Cost is about $750.00

Set up three, Exit the basement bathroom under footer through existing sump hole(currently unused) to a 500 gallon tank and use a grinder pump to pump to my septic tank. Obviously this is is the best method as I don't have to pay for the excavation. Cost to me is probably @ 2k after the dust settles.

If I put an interior pump/basin in the water/sewage needs to be piped 5' up through a 90*, 13.5' over through another 90*, 4' over 90* 2' down and out to septic tank which is a 12 foot run. All pipe is 4" with 1/4'/ft fall along horizontal runs.

I guess my question is between the first two if they are options which is the best and quietest.I would prefer the basin if it is an option as the tub doesn't have to be raised in elevation to achieve the slope to pump like with the up flusher. I don't want a slow draining tub or a really loud pump. I would prefer to avoid spending 2k unless it is necessary to avoid putting total crap in there no pun intended.
Thanks in advance for any feedback.

i dont know about Zoeller specifically, but i have done many 3 piece bathrooms with ONE buried tank and pump. i dont see the need for two setups, unless you want to spend twice the money....

The installation of a sewage ejection pump or a macerating toilet require upsizing the septic tank by 50% due to suspended solids not allowing enough oxygen for bacterial growth. Check the code before you do anything.

I already have a 1500gal tank for a two bedroom house which is already an upsize. Thank you for the heads up though What I don't understand about that though is that the tank is treating via anaerobic bacteria, are they referring to the SS entering the drainfield maybe. But then again it is code to install an effluent filter on all tanks now. I have seen undersized tanks that have been emulsified, but that was in high occupancy homes and not always with the basement sewage pump.

"i dont know about Zoeller specifically, but i have done many 3 piece bathrooms with ONE buried tank and pump. i dont see the need for two setups, unless you want to spend twice the money...." I guess I didnt word my post to well. I am weighing the the choice of a buried tank/pump vs the upflusher.
Thanks again for the input.

Yes, flow of effluent into the leach fied is the reason.

As for your set up. I don't like the Liberty set up. It's very noisy and cycles often and I don't particulary like the access to it either. We usually install the Zoeller setup. It is proven, fairly quiet and gives us the least problems. (and its less expensive) Not a bad idea to spring for the alarm set up at the same time.

Thanks for the input on the two set ups, loud pumps suck in a finished basement. Have you seen any instances of the installation of the pump affecting the operation of a siphon tank. I have a mound system with a siphon tank to dose the mound. I cant imagine it would but in South Maine I am sure you see your share of pressure distribution/Mounds. My plumber is kinda pushing the liberty, but as I said I heard it is loud. He keeps saying that he has seen too many of the Zoeller set ups fail, leaving you with a lot of mess and a tore up slab.
