PattiR. has your mother got a tempering valve in the system?
Has there been any body playing with the plumbing?
I have seen people capping off the centre outlet of a tapset because it wouldnt stop running – cross connection, people connecting a bib cock to the centre outlet – cross connection.
even saw a tempering valve being removed & then a breaching peice put in to fill the gap.
Call a plumber.
