Remember that geysers are the property of the owner and it is the owner's responsibility to maintain/replace the geyser, no matter where the geyser may be situated. This means that trustees, caretakers and estate managers must not get involved with geyser repairs or replacements. Furthermore, you cannot dictate to the owner or insurer which plumber may or may not be used. If the geyser is leaking water, you can and should disconnect the water supply to prevent damage to common property or to the sections themselves. Where common property has been damaged, you can and should get involved in the repair of the common property and the resultant insurance claim. But please leave the geyser problem,and any resultant damage to a section/s, to the owner/s of the geyser and section/s.
