We have a an old house and tub/faucets (1920's). The faucet has ceramic washers. The problem is we can get very hot water running through the faucet for about 3 or 4 minutes, and then it cuts off and gets cool to cold.
The problem is not the hot water heater capacity as we can take hour long showers upstairs, and run hot water endlessly in the kitchen (plus it's new and the capacity is huge). Plus it's just this tub and faucet. Has anyone heard of the ceramics swelling and shutting off the hot water? Any ideas? We stumped our friend who is a plumber, who said it probably had something to do with plumbing being from the 1920's. Has anyone ever heard of this or does anyone know anything about it?
We don't have the money to pull out the faucets and install new right now, and I'm wondering if it will really solve it or not.
