no 24 V power to my foam brush selonoid! Any ideas?

[partonken]

I have replaced all selonoids to foam brush weepers so selonoids are not the problem. I checked power to selonoids and i have no 24 V power to any of my weeper selonoids going to foam brush. Not a good thing, there all freezinig up!

Will need more info. Is there one weep solenoid for all foam brushes? Are they controlled by a weep thermostat?

Sounds like you have the dreaded Mark VII system? Or at least one thats similar?? The WEEPER solenoids you refer to shuts weep water off to a bay foam brush to keep from diluting the mixture when in use...Or at least thats how Mark VII designed their system...These valves are NO (Normally Open) meaning they are open when no power is applied....When power is applied they close. If you replaced them all, did you replace them with the right ones, normally open? If you replaced all the valves with NC (normally closed), that makes sense why you are freezing up! Let us know if this is the system you have?

If this is the type system you have, the solenoids you refer to are or should be totally seperate from a single weep solenoid that supplies weep for all bays. On My Mark VII, in the beginning, I did away with the individual solenoids and used methanol foam brush soap...Now I use a washer fluid/air injection system that winterizes the foam brushes and foam guns below 32°....Weep water is way too expensive where I live to throw it down the drain!

when you use the methanol foam soap do you still have the foam brush operatinal during the winter or is it shut down??

I've been using Blendco's methanol soap, it's been working great.

I don't have multi-able solenoids on my weep system. I have one normally open solenoid valve that controls the weep water for the equipment. On each bay I have a stainless steel high pressure check to prevent high pressure water to go into the weep system. Simple system, no problems

That is the reason for adding methanol to your foam brush soap, so it won't freeze below 32°. So yes, methanol allows you to keep the foam brush operational in the winter.
