What's happening?

Weak water or no hot water

Water that won't behave is often not your fault and not yours to fix. A single slow faucet usually is yours. The whole line of units losing pressure usually isn't. These answers help you tell which you have.

• Why is my water pressure so weak on an upper floor?Probably the association'sWho pays, usually: The association or landlord, when every upper floor is weak, because pumps, tanks and risers tend to be shared. A problem confined to one fixture in your unit is a different matter.
• What is a booster pump, and who looks after it?Probably the association'sWho pays, usually: The association or landlord normally maintains and pays for a booster pump, since it serves many homes. Condo owners fund it through common charges, and the declaration has the final word.
• Only one faucet in my apartment is weak. Who fixes that?Probably yoursWho pays, usually: An owner often pays, since a faucet and its stop valve serve only one home, while a renter reports it to the landlord. Declarations can draw the line differently.
• Why does hot water take so long to reach my apartment?Probably the association'sWho pays, usually: The association or landlord usually handles a central heater or hot-water loop. If the heater sits inside your unit, an owner may pay and a renter reports it.
• Why does my shower go cold when a neighbor uses water?Not clear yetWho pays, usually: A valve in your wall that serves only your shower often falls to the owner or landlord, while a crossover elsewhere or a building-side fault usually goes to the association or building.
• There's no hot water. Is it just me or the whole building?Not clear yetWho pays, usually: A central plant is usually the building's or association's to fix. A heater serving only your unit is often the owner's or the landlord's, depending on the declaration or lease.
