 Shower drain
Author: Dlockett (Non-US)

This is a strange question, but I am hoping I get an answer.
I have 2 cat toilets. One is n my laundry room and the hose that flushes out the toilet (water etc) goes into the laundry drain. This is perfect.
The other cat toilet drains into an actual toilet, so I have to flush the waste. Would it be possible to put the hose from the cat toilet down the shower drain, so the water just goes down that drain, like it does n the laundry room.
It is a shower that is never used so that drain pipe is always dry. If I can use it for the cat toilet it would solve 2 problems- cat waste & sewage smell from a dry drain.

Thank you

Do these "cat toilets" have cat litter and you are putting the used litter down your plumbing drains? Or does the cat toilet collect the cat's liquid and solid waste and that is the only thing that goes down the drain? Not sure what a cat toilet is, unless you mean an ordinary cat litterbox.

It is an actual "cat toilet" The litter is permanent & does not flush out with the waste. After the cat uses it, the solids are scooped out and out into a hopper. Then the bowl area is filled with water & Sami solution - then all the liquid waste is out with the solid. The hopper breaks up & dissolves the solid waste into the liquid waste & it all goes out the drain hose. So it is only liquid, no litter going down the drain.

They are designed to be installed with a laundry drain or you can put the hose into a toilet bowl & flush the waste manually.

I just don't know if there is a difference between a floor shower drain pipe & the drain pipe used for laundry.

Thanks for any advise you can give

The drain pipe for the laundry, called a "standpipe" is a several sizes larger pipe than what is used for a floor drain in a home. But if the only thing coming out of the cat toilet is liquid than I don't think it would matter which drain you used. Both drains eventually connect to your home's main sewer drain. Does the paperwork that came with the cat toilet give a preference for what type of drain it should be connected to, like draining downward or is upward ok? Its pump will only be able to push the liquid waste upward a certain height.

Also, if the liquid waste from the cat toilet has an odor it might be better to use the washing machine standpipe. The floor drain will not have any other liquid going down it to wash it out now and then. The laundry standpipe will get regular use from your washing machine.

no difference. the shower should be a 2 inch trap (by code) so it will handle the water even better than a 1 1/2 inch laundry.
you might want to run a small snake wire down the shower drain to make sure it is nice and clean. they are notorious for soap scum and hair because of the way they are used. pour some water down the drain as the snake wire is turning.

he said a 'shower drain' not a 'floor drain' . although there is not much difference. both have a trap right below the surface and both are probably 2 inch..

ok, thanks, I misread, thought about my floor drain in the basement (1960's house) and the opening under the grate is smaller pipe than a standpipe is.
