What is Causing Nozzle on Outdoor Spigot to have Low Pressure?

Hi. I am trying to figure out why the nozzle connected to a garden hose on an outdoor spigot has such low pressure. I tested the water pressure with a gauge connected to the spigot and it read between 50 and 60. The hose is only a couple of years old, and I bring it into the garage during the winter. The nozzle is only a couple of years old, and I had the low pressure with another nozzle too. I dont see any leaks. The valve is completely open on the outside and the shutoff valve on the inside of the house is completely open too. I replaced the sillcock two summers ago, it has a vacuum breaker as part of the sillcock. I don't see leaks at the breaker.

So what could be causing this problem?

You state you have low pressure from a nozzle on the end of the hose, do you REALLY mean you have a low flow rate? What is the length and inside diameter of the hose? What is the size of the piping supplying the water to the faucet and what type of valves are installed?

Have you tried the hose without the sprayer nozzle on the end? If you have good flow at the end of the hose your spray nozzle is probably clogged with debris and needs to be cleaned out.

Or better yet just unscrew the hose from the spigot and try that.

Try timing how long it takes to fill up a 5 gallon bucket straight from the spigot, then again from the end of the hose. They should be somewhat close.

50-60psi is pretty standard for a residence, so you're good there.
