Another curiosity with the water is that running faucets, sometimes the kitchen and always one of two bath sinks, the water seems to pulsate like a heartbeat. Sign of pump trouble?
The house might be somewhat posessed (might as well mention this whilst I'm at it)...ice maker on the Frigidaire has quit working twice for long periods of time; most recently, we had neighborhood power outage for a couple of hours night before last. Next morning, the ice maker resumed working and still works. I did a search online last time to see what might be wrong, and it sounded like it would the the regulator thingy on the back of the friggin fridge, which is too expensive to bother with if we buy it and DIY repairs. Water line for fridge from pipe to fridge is plastic, about 15-ish feet long....I'm not fond of overhead repairs, as they make my neck creak. Water runs from the door faucet, a tad slow....not enough pressure to get the icemaker cranking?
