Is it necessary to inform the owner to organize the guests to inform the property to deal with the water leakage problem?

If it is a rented house, the maintenance of the house leakage is entirely the responsibility of the landlord, so contact the landlord in time to urge the other party to complete the maintenance as soon as possible. Some landlords are lazy or ill-intentioned, and will negotiate with tenants to let them hire their own maintenance, and the maintenance costs will be borne by the landlord. Don't promise this kind of situation. After all, the house is not yours, and the water leakage belongs to the original problem of the house. After all, you don't know the initial structure of the house. If there is any problem, it is hard to say whether the landlord depends on you. So be sure to inform the merchant and inform the landlord.
