You need a macerator pump or a toilet with one integrated

Used this one at my last house. I built a bathroom near my pool and plumbed it in. It worked great. I drained it for winter. They do make an odd noise though you need to get used to. I plumbed it directly into my septic tank.

I have an apartment above my shop with a full bath and kitchen. Gets used daily and have had guests stay in it for a month at time. Septic system is about 5' higher and 120' away. Installed one of these over 4 years ago and it's been perfect. I have it buried 3' from the building. Last year I pulled the cap just to see if it was building up solids..... it wasn't.

If I had to do it all over again..... I'd use the same setup.

Toilet drains to a sewage ejector pump pit (sealed) in the basement floor. Once the level of waste water reaches a certain level in the pit, the sewage ejector pump pumps the waste water up through a 2" pipe into the main house sewer line (overhead in the basement). Then out to the septic tank by gravity. Vertical 2" pipe has a check valve to prevent waste water from going back into the pump pit from above.

yup, i installed one of these in my detached garage for garage/pool bathroom. I already had all the water lines and plumbing there for me since my garage had a laundry sink already there and the plumber said my drain line was large enough to do it. Been going strong for 3 1/2 years now with no problems.

In our area most homes have basements with plumbing below the slab. Old septic drain fields are being replaced with mound systems. Sewage obviously doesn't flow uphill so gravity systems must be converted. Effluent, or ejector pump systems are the most common conversion.

@48windsor , I would be surprised if those systems are not commonly used in your area. I will caution you about system sizing. You are adding flow to an existing system. In our area, that is a touchy issue with existing septic. I have seen a number of remodeling projects that went out of whack because of older septic fields and new requirements.

Years ago my state came up with a different license for septic installers. Prior to that, plumbers did it. I only did a couple of septic systems then but at the time they were sized by number of bedrooms, not bathrooms. It made sense to me 🤷‍♂️

Not sure how it’s addressed now.

My shop is lower than the house, and also about 300 ft away. I had to put in a dedicated septic tank with a submersible pump. It pumps to the main septic tank and drainfield. The pipe between is not that big - about 2" IIRC. It's worked fine for the last 5 years. Only trick was the 2" pumped line had to be routed at least 50 ft from the well, so it makes a big circle around the well before it heads uphill to the house. Not that big a deal, though.

Good luck,
MrFreeze

I'm an advocate of composting toilets. Put one in a remote cabin, house boat and in my shop. Easy installation, no permits and they work.

I have this same unit for my shop toilet. Well worth doing.
