Gray-water Irrigation System

The snow has finally melted and the frosts are intermittent, so it is time to redo the greenhouse watering system.

Water from the roof, showers and the clothes washer is collected in a 200 gallon tank.  I have diverter valves on the drain pipes in the crawl space that I turn on in the Spring and off in the Winter.

From the tank, the gray-water is filtered and travels underground to each of the 3 greenhouses via a 1" plastic pipe.  Each greenhouse has a shutoff to isolated the 1/2" distribution pipe that channels the water to the t-tape (flat drip tape) that runs the length of each greehouse bed.

This weekend, I cleaned out the supply pipes by attaching them to a pressurized hose, checked the filter system and started laying new t-tape.  I was excited because i had found some t-tape with 4 inch spaced emitters made especially for greenhouses. 

Unfortunately, once I had cut the the tape to the right lengths, set them up nicely and turned on the water, I found the company, Rain-Flo Irrigation had sent me t-tape with 12" spaced emitters.   They refused to credit me for the unused portion, so I am stuck with them.

Such is dealing with companies with poor customer service!  I will get the right stuff and try again when I have time.
