Weep valves do not need to be energized all summer. Aside from inflicting unnecessary wear and tear on the valve itself, once they 
get older they can become hot and trip the dedicated circuit which supplies power to the automatic computer cabinet or self service controls. Yes, we have seen people experience down time and service calls because of a weep valve running during the summer.
First step for all car washes:
First, turn off the water supply to the weep valve. This usually 
involves a hose bib (spigot) somewhere on the pump room wall that can be found by tracing the hose connected to the valve itself. If you have self service bays and an automatic, then there are two valves and two sources of water.
Car washes with weep mizers:
If you have a Weep Mizer installed at your car wash the process is 
much easier. Once the water is turned off, simply unplug the weep mizer and the valve(s) will turn off.
Self service car washes with thermostats:
Again, the water supply to the weep valve must be turned off. Then
the thermostat can be adjusted to the extreme position that turns the valve off. You will hear it click as you pass the ambient temperature and can feel of it or listen to it to see if the valve is on or off. Once you find “off” then turn the dial to the extreme setting (all the way up or down) without making the valve turn on again.

After shutting off the water supply, you simply remove the black wire from terminal # 207 inside the computer cabinet while leaving the orange wire intact. Incidentally, the black wire can be on either side of the terminal. The valve should now be off.

The simplest way to disable the weep valve is to remove the water weep relay located in the pump station computer cabinet. It should be clearly labeled as “water weep” and it is relay #403 on most of these machines.
Last step for all car washes:
Go out into your bays and make sure that your equipment is not weeping.
