We have a building that we finished construction on about three months ago and all the sinks were giving out hot water (10 sinks) but now the furthest one from the hot water heater will not give out hot water can you please help

If you turn on just the hot on that one tap will it ever get hot?

No, we have tried running the water for at least ten minutes and the water still won't get hot

Remove and clean the cartridge, sounds like a clogged hot inlet.

Turn off cold water stop underneath the sink. Make certain the hot water stop is open. Open the faucet, any water you get will have to come from the hot water side. If it is not hot, you must have a cross contamination some where. If you don't get any water you must have a blockage some where. Probably in the faucet it self

Turn off hot water supply to water heater then check to see if there is still water pressure on the hot side of the faucet, if you still have water pressure then somebody piped cold water to both valves to sink.
