Hi. Had expensive new shower fitted in my mums place after she passed, prior to sale.
3 months later, had a call from neighbour below because water leaking through her lights. Checked house and shower was on even though totally unoccupied. 5 days prior we had a house viewing. Bills suggest viewer turned shower on and left! Plumber inspected a week later and said he needs to replace digital valve and pump as faulty.
Question: Can a faulty digital valve/pump cause a shower to turn on by itself or is this just bull?
