It has water!


Today i hooked it all up water and everything to test the pressures and the seals of the pneumatics and the PVC. The test was successful and i found that i need to re-think the float in order to get the most push for the amount of water used.

After we get the switches mounted and the float working i will be able to start to experiment with fish and sediment!
