Basement Utility Sink

[zoomiezoom]

Hey Everyone
New User here. I was wondering if anybody here knows if I could use RectorSeals Magic Trap and Magic Vent with an above floor sump package? Basically, I have a 100 year old foundation, under a newly gutted and renovated home. Haven't begun anything yet, just trying to figure out a way to properly install a basement utility sink that is installed according to code and looks and functions properly. I don't want to post the link to the magic trap because I don't want to look like I'm plugging it or anything.

Depends On Your Plumbing Code

Whether you can use any Air Admittance Valve(AAV) like MagicTrap or MagicVent depends upon what Plumbing Code is in effect in your jurisdiction and what type sump ejector system you have.

The Uniform Plumbing Code prohibits the use of AAVs altogether and pneumatic type ejectors usually require their own independent vent run to fresh air with no AAVs attached anywhere on their drainage system.

Call your local plumbing code office.

It is the only place you will get a proper answer.

Hey thanks a lot. I was hoping to have an easy solution. Not sure I should tackle this one by myself.

I ran into a similar problem on a really large renovation project for a client, the basement was being fitted out with among other things a full on bar and game room, client made an add on to include a stand alone island with a sink in it. This caused a major headache plumbing wise, getting the water there and from there wasn't easy and involved cutting up the concrete for the plumber, the big problem was the venting, spoke to the local plumbing inspector and they allowed AVV venting at the sink site.
So like already mentioned, call your local building department, more often than not they will have a solution or allowance that will work.

The funny thing is I called the building department and they didn't know what I was talking about ("what is an AAV?). I actually got the name of the building inspector who I am going to call today to see if he knows any more about it. The vent and the drain is the only problem but maybe the inspector can actually give me some good advice about how to set it up.

While you may be able to use an AAV on the sink side the pump crock would require a vent through the roof as they are air tight and water will not flow into it without being vented.
