In my area I do not have a big plumbing/irrigation wholesaler right in town. The nearest one of any size is 1.5 to 2 hours away, approximatley 120 miles. For repair and maintenance, how much inventory do you normally carry on hand? I don't want to have too much cashflow tied up in stuff I may not really need or utilize. Like different replacement controllers, etc. But I do plan on keeping a number of valves, heads for replacement parts and replacement. Our area seems to use a lot of Rainbird components. (Possibly a Home Depot convenience.) Any here use an online supplier? Shipment methods, costs, etc?
