I would like to install some drip irrigation in a plant bed in the front of my house. Getting it tied into the sprinkler system is not an option here for reasons I won't go into. However, we do have a hose bib fairly close by but there is a concrete walkway between it the plant bed. We are going to be replacing the walkway soon so we will have an opportunity to run the hose over to the plant bed. I'm thinking I'd like to install some kind of sleeve under the new walkway to make a tunnel for the hose. That way maybe I can replace the hose in the future should the need arise.
We're not talking about a great distance here, maybe 5 or so feet. The material would have to be flexible enough to bend under the walkway but rigid enough to hold its shape under ground.
Does anyone know of a product or material that would work here? Maybe a thin walled PVC pipe?
