After replacement of an electric water heater, I get no water flow (hot or cold) from some faucets, normal water flow from some faucets, and no appreciable amount of hot water flow to my dishwasher or washing machine. Before replacement, I had low flow on the bathroom and kitchen faucets; now I have none. One of my showers has very high hot and cold water flow; the other one just trickles. This doesn't seem logical to me since ALL hot water leaves the tank by the same pipe. Can you help?
