New member, old problem. Cycling pump

One other thing you need to keep in mind.

If the water pump cycles on every few minutes, up to every hour, you most likely have a leak. The more often a cycle the bigger the leak. After a season of bouncing down roads and a winter season of changing temperatures, there is a good chance for a leaking connection.

Most newer RV,s (last 15 years) use tubing and connections that hand tighten. Open up the cabinets (kitchen and bathroom) and reach up and tighten the tubing connection for each faucet. If you have an inline water-filter check it's connections too. The outside shower connections can usually be gotten at inside the sink cabinet by the outer wall. The shower may have an access panel to unscrew to check faucet connections (mine was in the bedroom wall for shower).

The sink strainers cause low flow or pulsing of the pump while water turned on. Pump cycling (comes on when no flow was expected, and cycles off). Someone leaving a faucet slightly on, or some toilet paper caught in the flange seal opened for flushing (BIG problem if water keeps running to fill holding tank).

My original kitchen faucet had screens underneath where the feed tubes met the faucet base. They were severely clogged.

Sometimes aerators and sprayers can get caked up with mineral deposits rather than (or in addition to) debris. Depending on the minerals, these can often be removed by soaking the parts in vinegar or some other acid for several hours. Vinegar is nice to use because it's readily and inexpensively available, and it's safe for human consumption so you don't have to worry about rinsing every last bit out.

That's what I had with the original, some debris in it that I just couldn't clean out so I bought a replacement. But that pump doesn't make enough pressure to even have an aerator. All I know is water comes out of the faucet freely without it in there.

Faucet aerator shouldn't affect the sprayer.....

Have you checked the water lines on faucet?
Sometimes they have restricters in the end of lines for faucets

Bathroom sink has an aerator correct?

Thanks rjxj.

Some aerators have multiple pieces with very small holes or slots. Sometimes you can disassemble them and clean them up. I have used compressed air. They use them so you dont get a sort of blast of water that splashes all over. More gentle.

Doh!
I think I can answer my own question. Everyone says to check the aerator and I replace it with a new one. However just taking it out and I get a great flow. Don't see what good it is to have it in there. Obviously restricts the flow too much.
