It is a 9 room guesthouse. I had tanks feeding the rooms by gravity but was not enough pressure. I installed the pump and ever since have had trouble with too much pressure. A toilet doesnt close properly after flushing, a pipe breaks etc and the pump will run continually till I find the problem. I have had 3 or 4 incidents in the last week. I have just taken over the property next door and they are up the hill and have the tower in the picture. I thought of pumping from the first property up the hill and up to the tower and then gravity feeding back. I thought then if I had a breakage it would not really affect the pump and I could just fix it in the morning instead of running around knocking on doors at night asking if the toilet is running. Thank you for your interest.
