My cousin has a well at his Lake Arrowhead residence. He has city water and a well so he can take advantage of using his cheaper well water primarily for irrigation, but when turned on, will supply water to his entire house. Besides the stop float falling to the bottom of his 500 gallon tank (estimated) recently, it seems to be operating without any problems. He did have a well specialist come out who recommended he install a shut off valve to the tank discharge line for ease of maintenance, does anyone see any problems with this set up? What type of maintenance do you recommend? He does have about 3/4" of silt in the bottom of his storage tank, which we plan on sucking out soon, can any of you advise the best way to remove the silt? Can you experts give me any tips to keep this running in good condition? Any and all comments would be appreciated!
