Pump rapidly cycling only with sink faucets

2009 Keystone Raptor 3712TS. My pump is cycling on and off when using the bathroom or kitchen sink, but not doing it when using the shower or toilet. I saw someone had the same symptoms and when they removed the flow restrictors from those faucets, the problem was solved. I just don't know where to find the flow restrictors. The kitchen has a spray faucet. I took the "nozzle" off but didn't notice a flow restrictor. Can anyone point me in the right direction?

Thanks,
Jesse

Jesse, try this cycling is not normal. Go to your water heater, while cold, and pump on. Then open the pop off valve" the lever on the upper part of the heater" Pull the lever to release the pressure and make water run out.
What is happening is the lack of a "full" water heater tank is making the pump want to pressurize the unit all the time.
This is typical when the unit has set for a spell or you have drained the system.
Good luck

Look for an adjustment screw in the end of the pump head.

What you experience is normal. Don't worry about it.
The pump has high volume and when you don't use high volume it builds up pressure and shuts off.
Your toilet and shower have higher volumes than your faucets.
Everything sounds OK. Mine does the same thing.
