Use Cleanout for Bar Drain (No backwater protection?)


Hello,

I am looking to put a wet bar in the one area of my home. There is currently a cleanout port there (see Picture). I know that I should and will keep clean out access there even if I tap into it to drain for my wet bar, but was wondering if I should be concerned about backwater protection? There are other backwater valves located upstream.

I am pretty sure they don't make a backwater valve that can be mounted vertically, but I could be wrong.

Are there any options to keep some type of backwater protection?
I few things I looked at:
1. Installing a 1 1/4 check valve prior to the cleanout.
2. installing a 3 inch backwater valve under my bar counter, but before the sink drain (i.e. Floor Cleanout -> 90 degree elbow -> Backwater valve -> A few more bends, PVC, and a reducing coupling -> sink drain)
3. A plain old ball valve (yup, if left open--there might be a problem).

Is any of this possible, am I missing something, or do you think I don't need backwater protection??

Thanks
Nate

I got a brilliant suggestion, Just indirect drain your bar sink into the floor drain by the back water valve. That is perfectly legal under IPC code.

Is there not a backwater valve outside the bulding?

I could do that but I would need a sink pump to get it up and over there if that is the case I might as well tap into the main stack. That was our original plan until I found this underutilized drain/cleanout. The bar is about 20 feet from that drain for an air vent.

Not sure. I guess i will have to ask our town. Is there usually a backwater valve outside? This is residential property.

I have two inside. One near the floor drain by the hvac water Hester and another for the bathroom, both up stream of where I would like to out my wet bar

Thanks
Nate

The simple fact is that a swing check is a horizontal valve and a spring check would likely get plugged up.

Around here we have put backwater valves outside however depending on if youre in a basement setup with this it may be too deep to get access for easy cleaning.

Another option would be to open the floor, cut in a backwater valve upstream from the cleanout, and a wye fitting upstream from the backwater valve to serve your sink.

Do i have to dig up the concrete? Would there be a problem with using an elbow off of the floor cleanout and installing a backwater valve off of that? Then I would connector my drain as appropriate? I can hide all of this under the bar sink Cabinet.

Just pump it into the floor drain with a bucket sump. https://www.amazon.com/Hydromatic-HP.../dp/B005XOLC8W

I was looking at way to avoid that option. I have attached a pic/diagram of what I was describing earlier.

I know this is a little non-standard, but it will give me additional backwater protection.

I'd probably change that 90* to a sanitary tee and put the cleanout in the top of it. Not sure why that wouldn't be legal as long as the backwater and cleanout are accessible for servicing, except it's gonna look like the front end of a dung beetle.

Digging up concrete isn't as bad of a deal as it sounds and you won't end up having to hide anything later.
