    here is the setup trying to help my pop out

    3/4HP Goulds model C6470164 (pump is 20 yrs old) lake pump plugged into outlet 10 feet from shoreline 115 line run from outside outlet to a 30 amp circuit which is on the main electrical panel for house

    Coming directly off the pump has a 4 valve spicket like this http://www.berryhilldrip.com/images/62032FauPic.jpg in which 3/4 inch polyethylene tubing is connected. He primarily only uses 2 of the four lines. First line has the "stake in ground sprinklers" coming off the tubing for watering the lawn covers the lawn great... (poormans irrigation but works for his setup)

    2nd line is for watering a garden bed

    The most efficent way @ the moment is he walks down into the basement to turn on the circuit which turns on the pump (not very pratical)

    Question is:

    Is their such a thing as a pump start relay with a timer built in timer? This way it would simply turn on the pump and only 1 valve is open (single zone) which waters the lawn based on a schedule. In my limitied reading it sounds like most pump start relays are connected to a irrigation controller. However its sounds like a controller is neccessary when you have multiple zones (valves)? If we wanted to keep this really basic as to simply control 1 zone (have one valve open)....Does such a pump start relay exist with a built in timer exist?

    He does not have a pressure tank or pressure switch etc..The only way it turns on is if we turn on the breaker..Simply put I want to know if we can automate turning it on (once a day) at a specific time.

    Any other suggestions are welcome

    thanks in advance

    Better to install a baby pressure tank and let a pressure switch control the pump. That way, you can even close all the outlets without having to do anything with the pump.

    But to turn on the pump doesnt he have to walk down to the spicket to turn on the water for the pump to engage? He's old there is stairs and I would prefer this be automated thats why a timer to turn the pump off and on would be ideal

    Yup............you can use the zone on the timer to activate the pump-start relay.

    A pump controlled by a pressure switch does not need a relay. If a controller is actuating zone valves, that is a separate matter. There does not need to be any sort of connection between a pump and a sprinkler controller. The tank/switch combination is the best way to protect a pump from a zone valve failing to open. It also allows manual operation by way of a hose bib.

    There are no "zones" in this system, as I understand it. Any fool is going to install a blowoff should the pump deadhead.

    I'm with you but how does one "automate" to be put on a schedule, If one does not have a controller. Sounds like the scenario you lay out is great if I want to walk down to the hose and turn on the sprinkler etc.

    Tell us why, and make it good, why there cannot be a pressure switch and a tiny (less than 5 gallons) pressure tank.

    "I don't want one" isn't a good enough reason to do the wrong thing.

    Make a complete system with tank and pressure switch, and the job is done. By all means include a pressure relief valve if you want one, but I might leave it out, when it might be necessary to tweak a pressure switch to allow constant flow with a small amount of water used by a garden hose. (when you do that, there won't be very much leeway for a relief valve to function effectively)
