How do I get a high-pitched whistle out of my kitchen hot water facet?

Question

It's only when I turn the hot water on. Only in the kitchen.

Answer 1

most of the time it has to do with low pressure, air pockets form!! mostly from old dirty pipes. try to see if u can turn the pressure up and if that doesnt work new pipe and new facet

Answer 2

I am assuming it is the type of faucet with separate handles and not just one handle.
The most likely cause is a worn valve washer. these are little disks of hard rubber scewed to the bottom of the valve stem and sealing against the seat and you need to turn the water off (usually another set of valves under the sink but sometimes just the one main valve near the water meter, likely in basement)
These washers are cheap and can be bought in assortment packs. It is important to match the new washer with what is supposed to be there. You need to be a bit handy for this.

Answer 3

you have a blockage in your hot water line leading to your kitchen. or in the faucet itself. take the hot water supply line off the faucet and run at full into a bucket. don't forget to turn off the supply valve under the sink before disconnecting. let run for a while, if whistle starts and stops you have probably cleared the blockage, if no noise at all, problem is probably in the faucet. if your handy remove the faucet, disassemble if possible, and clean it, if not you could try blowing backwards through the faucet to clear it. compressed air and a blowgun is best.

Answer 4

Check the shut off valve under the sink, and be sure it's wide open. Give it some "exercise" by opening and closing it a few times, then leave it wide open. Sometimes the bonnet packing nut will leak if it's old. That is the nut on the stem of the handle, and you can usually just tighten it a bit and any leak will stop.

Answer 5

O rings and rubber gaskets ,and teflon tape for any threaded sections of pipe .
