This past cold snap has me rethinking things, again! Even though I have a blow Down, washer fluid injection system installed on all low pressure hoses, its not totally perfect. Last week I had people washing cars at -2°. I have no other problems staying open at these temps other than the Foam Gun and FB hoses...Even though they get protected correctly @ 32° with a blow down WWF injection cycle, when someone tries to use the foam gun or FB @ say 0°, I believe the soap is "Flash Freezing" in the hose. The Foam Gun is worse since the coiled hose is 35' long. When the foam flash freezes, no amount of air or washer fluid will unplug it.
I refuse to weep water in the LP hoses since my water/sewage bill is bad enough compared to income. I'm now redesigning my weep system so I can blow down the HP hoses and shut down 2, 3, or all 4 of my bays depending on daytime temps. Hardly anybody washes below 20° and it just doesn't make sense to stay open 100%.
Another solution, even if I only had 1 bay open, would be to disable all LP functions below, say 20° and post it in the bays. This would at least allow the "Die Hard" to wash the salt off their car if they choose to do so. Does anybody do this? It would be fairly easy to install using relays and a separate thermostat. I could always use output 2 on the weepmizer, but its set at 32° and I think its a little high for what I'm trying to accomplish.
Keeping a bay open during extreme cold, but limiting functions, may be the way to go, I don't know? Your thoughts? This business is, most usually, very competitive so we need to always be thinking of better ways to maximize the bottom line. I'm tired of wasting $$$.....
