My kitchen sink, which is at the end of the water supply, has really low pressure on the hot water only. Why is this?
COMMUNITY FORUM
1- Pressure drop do to friction loss
2- Galvanized piping with mineral deposits inside
3-Globe pattern valve partically closed
4- Kinked water supply either riser or copper tubing
5- Dirty aerator
6-Inadequate design
7- flow restrictor installed in valve body
8- Washer other other obstruction blocking full flow like a bib screw fell down a supply tube
9- Cheap imported faucet
10- Expensive brand name faucet which is made of poor quality or poor design
11- To many fixtures used at the same time SEE # 6
12- Hot water line hooked up to return circulation
unless I can see the condition and trace out the lines then here are just a few guesses
