I cannot FIND THIS LEAK!!!!

[Kevin_1963]

This, by far, was the craziest thing I've ever worked on.

Ok, so more dye was put in the system. Went back the next day to find the evap full of dye. Perfect, the evap is shot. Just before I'm about to condemn it, something tells me to check around a little more - why is there dye on the floor of the freezer? And maybe I've been watching CSI too much, because I see - a spray pattern on the evap?

Pump 'er down again, ramp the nitrogen to 300#. All the sudden PSSSSSSS - out of a braze joint right by the solenoid that runs behind the evap - spraying a pretty picture. Drop the pressure to 200 and literally NOTHING. Spray soap shows tiny bubbles. Ramp it back up to 300, blows the soap off the joint. I've never seen anything like this in all my years.

Rebraze joint, vac and recharge - returned two days to a full sight glass.

Perplexing, for sure.

Nice trick .

Had a unit in county jail house kept loosing about half the charge in three days. No leaks any where. Marked caps. Sure enough next time out low again caps had been moved. Talked to seargeant at jail I put Uv dye in system. Seems jail house had a black light. Poor guy got three months added to sentence. He only had three weeks left.

I worked at the county jail also. One of the reason we cannot served at the Jury. We might ended up seeing each other at the jail .

I had an issue where one of my king valves was bleeding off refrigerant once the pressure got about 250 psi. I would check the valve and see if it bleeds once the pressure on your nitrogen bottle starts to get around 250 + just close the valve completely and see if it holds. If it does than it's definetley the valve.

What is a buzz bulb ?

Yup! They do it. Had a lady customer that I went back to three times in a month. Ran entire system each time. No leaks. Recharged installed caps and marked caps on bottom. Sure enough Monday morning back out again. Caps had been moved. Noticed motion light right above unit. Found bulbs had been loosened. Told customer to run down to hardware store and pick up buzz bulb. Which I installed for her. She called following morning. She said it went off at 9:00 PM caught next door neighbor's kids with a bag and a piece of hose. Neighbor paid bill.

It screws into a standard light socket and buzzes when you turn it on.

[Poodle Head Mikey]

Is "buzz bulb" a standard term for this item?

Does it look like a light bulb but makes a noise?

How loud is the noise?

I am sure that I have never seen or heard one. Or even Heard of one - before now.

I have not seen one in a few years. But it was shaped to fit in a light fixture with a speaker on the end. Last time I saw one was in Lowes. Check amazon.com.
