We just did a small bathroom remodel. The sink and the bathtub are connected to the same hot water line. Now I am not getting any hot water in the bathtub but the sink has hot water. The plumber did some adjustments under the sink and it worked worked . Today when I tried to turn the hot water in the tub Iam getting only cold water. The house is less then one year old and all the faucet are in good condition. Can anyone have any idea what the issue is. Thanks
The only thing I can think of that the plumber adjusted under the sink is he swapper the hot and cold lines which had been installed backwards. If the hot water tank is at a distant location it would take sometime before hot water reached the faucet. The same would be true if you have a tankless water heater; standing water in the hot line cools when the faucet is closed for awhile.
