hiI have very low pressure only on the hot water in my kitchen sink. Cold water is fine. Can anyone recommend a water pump/power shower i can use for boosting my hot water in the kitchen sink tap?Ive already tested the faucet by swapping the water supplies.thanks
Why do you need high pressure from the hot tap?
Your hot and cold water should be at equal pressures. I suspect you have a restriction in your hot water supply, possibly the under the sink shut off or is semi closed or the hot water tank main shutoff is partially shut off…or the hot water system is clogged somewhere.
To determine if it's the water system or the faucet, turn off the hot water supply valve and remove the supply line from the faucet (or remove it from the spigot on the wall and use a spare supply line). Turn the water on full and direct the water into a bucket to determine the flowrate (like you did earlier from the tap). Now repeat with the cold spigot. Did you get the same amount of water over the same amount of time (same flowrate)? If so, there's something wrong with the faucet, and it needs to be repaired or replaced. If not, you likely have some restriction in your hot water system, which could be the supply valve itself. Or it could be something anywhere from the water heater to that spigot. Next you would have to do something similar (measuring the flowrate) at various faucets in your house (including a bath/shower) to see if it's a house-wide problem or just local to that kitchen faucet. One thing that does happen in hot water systems is that debris from scale buildup in the water heater can be flushed out into the pipes and create restrictions in the valves that could affect flowrate.
