Anyone a plumber... im in a private let house ... and my hot water taps I'm kitchen and bathroom both have low water pressure, landlord said he had this problem before I moved in but he thought the plumber had fixed it and it's back .. he said it was an air lock bubble. If anyone knows or is a plumber and able to come solve the problem could you let me know .. and a price and my landlord will pay the repair? Don't want to fix it myself and the problem to be persistent
