Clear PVC pee trap for condensate - Where do you buy?

I think yo are looking for an EZ Trap

I recently purchased one of these. I have two zones in my house and one had been installed in the attic, so that's how I found out about this device.

I called a local plumbing supply store based on their list of distributors on their website, and they had it in stock. Normally, they don't sell to DIY'ers, but I got one.

For pros, they can buy them for about $9. I got mine for $22....the EZT-110 model.

Note on the webpage supplied above that the EZT-113 is sold in a 4 pack only.

If anyone needs one of these EZ-Traps and can't find it local, give me a shout and I can hook you up. Not really promoting, just giving an option.
