i worked on pulling the old hot water heater out of place. to do that, you have to shut off the water. the water shut off valve is up near the water tank on the roof. i don’t have a ladder that can reach that high. we live in a house with tall ceilings and two stories. i need a 20 rung ladder to make it all the way to the top. my ladder is 13 rungs. so, to shut off the water, i waited until the pump kicked on which let me know the water level was as low as it would go. i quickly shut off the breaker
