Had enough of this summer bs

hows this for summer, im fixing to put in some underground sprinkling today
i have no idea what im doing, but i know there is a 1.5 inch pipe running from the back shed to the side of the house (underground) and i picked up 100 foot of 1 inch pipe and all the couplers i need to put it in and install 5 heads

i allready jimmie rigged up the pond pump to divert water from the waterfall to the pipe (by means of a manual valve body) and hopefully i can get her licked
