Adding additional air solenoid to HWH aux air compressor

While I was waiting for my rear pressure switch to replace my leaky one, I added a normally closed air solenoid valve to the air line that goes from the aux compressor to the HWH leveling system and wired it so when the compressor comes on the valve opens .  This means the air in the aux air tank only goes to the air bladder seal.  This has increased my time between the aux compressor running from 5-6 hours to almost 2 days  :)) .  This will not affect the HWH system because whenever you call for air to level the coach it runs the compressor which will open the valve.  If for some reason in the future the solenoid was to get stuck in the closed position, I could use the air tank switch to fill the main tanks and still level the coach until the valve was fixed.  Finally one advantage of having the air tank switch.  Still would like to get more than two days, (maybe a future project to rebuild slide bladder valves) or am I being too anal about air leaks and instead should settle for what I have?  What do you'all think and do you see any potential problems with what I have done?
