water heater

Water heater, which is 20 years old, was making noises last year but when the repairman arrived, the noises had stopped. It was good the rest of the year but this week it started making noise again. Margaret called the plumbers to book an appointment to get is replaced (no rush) first thing this morning. I then went upstairs to shower and found the water tepid at first, but then increasingly cold. Margaret reports that the heater no longer makes noise. 

Replace the whole thing this afternoon. Great hot water now.
