If I leave the 120 volt air pump on during the night I have air to flush the toilets. If I shut off the 120 volt air pump & turn on the 12 volt air pump I run out of air & the toilets won't flush. The gauge on the 12 volt air pump shows air pressure. Is the 12 volt air pump not plumbed into the toilets?

Thanks for any help...............
