After this summers heat and the fact I put in a new mostly perennial landscape in my front yard, watering became a chore. I ordered a bunch of drip irrigation products from Drip Works. Now in my tests so far I see this as an awesome tool for my landscape business: Less time spent watering in new landscapes, better plant survivability, water conservation, etc = happier customer, more referrals. My questions are: What should I watch out for to make this idea work? Do you warranty it? Set up a maintenance plan? what kind of maintenance does it need? Do you have a favorite way of installing it? How durable is it if someone walks on it when its buried under the mulch? I'm trying 1/4" and 1/2" drip lines, misters, spray heads, pressure regulating drip emitters on 1/4" lines. Its weird but I feel like the plants aren't getting water because you don't see the mulch all wet, yet they are growing so I know its working. Thanks in advance for your thoughts, Roald.
