Hi
I just had done some work in my bathroom but now when I turned hot water in kitchen then no hot water in bath and sink upstairs ,please help

Thanks

What happens when you turn kitchen sink faucet off. Do you get hot water in bath/sink upstairs ?

If I tuned off in kitchen then its OK ,hot water coming in bath and sink but soon as I turned on in kitchen then no hot water upstairs

It appears that it may be either Low Pressure and / or Under-sized pipes and/or combination of both.

Do you know anything about the plumbing plumber installed in your house ?
Do you know what's the pressure in your house ?
Is it hot water only ?
How big house do you have ?
Did they do anything with hot water heater ?

Plumber did the job he chang bath taps and new line in wall taps

There is a system to follow with installing new water lines as well adding new bathroom to existing house. You have to take in consideration overall pressure, number of existing plumbing fixtures and number of new plumbing fixtures + size of existing pipes. You cannot just add onto existing plumbing. If you hooked up your new bathroom on existing 1/2" water line for kitchen faucet + you had low pressure to begin with = than you will have problem that you are experiencing now.

I would strongly suggest that you call your plumber back to take a look at it...

No I don't know anything about plumbing ,some one did it for me he just change the bath taps line to wall I have 3 bedroom upstairs and bathroom and 2 down stairs room and kitchen only hot water problem

Call the plumber back. He needs to re-check his installation...
I assume you didn't have this problem before the remodel, correct ?
