Can you as landlord, stop water and electricity to your own house rented to tenant not paying rental?
Well, cannot! But, if it is mentioned in the tenancy agreement, may be.
Premier Model (M) v. Phileo Promenade Sdn Bhd  and John Denis De Silva v Crescent Court Management Corporation (2006).
These are two cases where one says if it is written in the tenancy agreement, you can cut water supply if tenant does not pay rent.
Notwithstanding, De Silva case proved that cutting water supply which can detrimentally affect the health of tenant is prohibited.
