I recently purchased a lake home with an underground irrigation system on city water. The system has four 4-zone controllers (3 different brands) so I assume it was installed over a number of years.
The former owner (a home builder by profession) had purchased a pump which is sitting uninstalled on the dock. He also tied in PVC pipe to the irrigation system. This pipe stops at the shorline. He installed wiring in conduit from the house to a power pole at lakeside but the wire has not been tied into the circuit breaker box. He also purchased a Hunter relay.
I'm now looking to complete the installation and I'm trying to understand what his plan was but he's unavailable to answer questions.
First Question (finally)--The pump has a pressure switch which I understand will turn the pump on when an irrigation valve opens and the pressure drops. Why would a relay be required and where would it be installed ?
Second Question--The lake level fluctuates by 10 feet over the course of a year. What kind of piping should I use to connect the pump to the PVC on the shoreline ? Its about 40 feet away.
Thank you for your help.
