Just got required by a bellevue, wa inspector to add a trap seal primer to a condensate waste receptor...has anyone else run into this? I thought that the condensate maintains the trap seal just fine... any thoughts?
Trap Primer required? I didn't think so...

Our code in Florida makes it a bit vague. Leaves it up to the AHJ to decide!
Code 1002.4 "...Where a trap seal is subject to loss by evaporation, a trap seal primer valve shall be installed..."
Talk about a set-up for...
In my area, you can get away "without" installing trap primers on floor drains in a commercial kitchen area. The floors are going to be cleaned daily by a hose reel.
But for those gang restrooms in the same restaurant, you have to have trap primers for the floor drains. One would think that they would mop it at least once a day. Yet mop water drainage doesn't count! Go figure!?!
To top that all off, sometimes the spec's go above and beyond the local and state code and ask "for trap primers on all floor drains." Talk about a bummer if you miss that on the estimate.
:whistling2:
Point being, is that sometimes the "absolute" law/code is better than having a "vague" one.
Cheers!

The left bowl is only 4" deep with a ISE disposer puts the the hose barb of the disposer at 8"+/- below the sink. The discharge leg of the air gap is at 8"+/-and pointing at an angle down. There was no way to get it level more or less right.A little off topic but PlumberDave, how in the world can your airgap be below the disposer connection? Your airgap should be above the flood level rim of the SINK
I gotta say this was a job I was making right behind one of our "TECH's". The company was fined the tech was fined no permit no license water repipe in a real tight butted district. I was going in under a gun, PO'd homeowner, inspector and boss.

I am having a similar situation regarding floor sinks and trap primers, I am starting to change my mind about this. I think we should have them on floor sinks. Use "what if" situations here. What if the kitchen closes over the holidays, maybe they shutdown for a few days for repairs or renovations? Could the trap seal be evaporate?

Cooking oil will work, but RV antifreeze might be a little more user friendly on the drainage system.Screw that pour the used cooking oil down will slow the evap

Trap Guard® solves the problem of infrequently used drains by eliminating the need for a trap primer while preventing the emission of sewer gases and the backup of raw sewage into living or work areas. It is much less expensive, much more effective and much simpler to maintain than a trap primer.

Jackhammer the floor up! run a primer line to a basin!.........or put in yer trap guard LOL
Same rules up here in Ontario. Any floor drain must be primed with a YEAR ROUND priming device, or install trap guard. I always like to use a HRV.

It being Bellevue and all, it's best to just give Tullis and his guys what they want and move on.
I did my last job in Bellevue last week -- Mark couldn't find anything wrong with my work, so he started picking on the HVAC contractor installing the gas piping.
I've got 3 years left -- Between Tullis, his minions and the new tolls scheduled for the end of the month, it'll be a very cold day in hell before I cross that bridge for work.

We did a few large commercial jobs lately and something similar was required, had a real light spring in it with a plunger. not a fan of anything mechanical in drainage, so i like the ones you show here:thumbsup:

I think an automatic means of maintaining a trap seal doesent nessesarily mean a trap primer. For example a shower valve will maintain a trap seal automaticaly but if you remove the valve and leave a drain it would require a primer.
So depending on the use of a floor drain or sink the inspector makes a call. Any floor drain pretty much needs it. Floor sink depends on how much constant use and of course the inspector .

Yes Ron, automatic means is definitely the issue in question, but my question was why a constantly running piece of equipment, constantly draining condensate, which dumps into a hub drain specifically installed for that purpose (not a floor drain), does not constitute "automatic means." Of course, I just bucked up and put a trap primer in, since it was Tullis and he can't be reasoned with, but the condensate that dumps into that trap all the time puts more water into that trap than the trap primer which I installed.
I've reached the point in bellevue and renton where i just put in trap primers on all floor drains, floor sinks, and funnel drains.
Some times i swear they write there own code. But if the job is permitted you can usually assume it was done correctly.
Last time i checked they dont allow trap gaurd because it obstructs the full bore of the pipe. But that was awhile ago.
