Water pressure discrepancy mystery

[Rmack1]

Here's a puzzler;

After letting my TT sit in the storage yard for 6 months, except when I took it to have the roof re-sealed, I put it on the road for our summer snowbirding.

All systems checked out, much to my relief, except one small thing. The water flow in the kitchen sink was much slower than the robust flow in the bath sink and tub/shower. I was at Sunrise RV in Santa Barbara on our first stop North, and it had high water pressure.

My adjustable water pressure gauge/regulator was set a little high, but still I had a skinny flow from the front sink. Then, another potential disaster then cropped up which scared the hell out of me.

The kitchen sink faucet started leaking! I couldn't turn it off unless I held it down or closed!

Turning down my variable water pressure regulator to about 35 psi cured this, thank God. I would have had to go to my potable tank and use the water pump, and turn it off when not in use, and keep it filled. Do-able but frustrating.

However, the front sink flow, which had been improving, went back to a slow flow.

After we pulled to Coastal Dunes in Oceano, the flow to the kitchen sink, though still slower than the bathroom, seemed to improve. And even more importantly, it's not leaking.

Whew!

What could all this be? One thing I thought; I had left open all the faucets so that the water would drain down to the tank, preventing the rare (for Southern California) freezing damage to the plumping, and preventing over-pressure to due to extreme heat :(not so rare in SoCal).

Could a bug have crawled up there and died? And now it's slowing getting washed out?

You need to remove aerator again and then turn on water Hot and Cold sides and BLOW feeder lines and faucet valve/cartridge clear

If cold side still remains lower flow then you would need to disassemble faucet and clean/replace clogged cold side

Unless rain water has been collected for 'potable' water use the water supply up there is still going to be hard.

Cleaning the aerator helped a lot.

There was chunks of white stuff blocked by the first plastic deal. I removed the small hole flow restrictor insert from that, and found four screens in there. I took out three and left the one. Hot water flow is now very robust, but cold is only improved.

It's totally workable now, I'm just still wondering whats slowing down that cold water.

It's no doubt those white large granules. I hope I can flush them through.

The good news; I think the water up here is going to be softer, thanks to the plentiful rain they've had this year.

Did you clean the faucet aereator

Considering it's only the one faucet, and the kitchen at that, more than likely it's the aerator at the end of the faucet. Unscrew it and clean the screen out. Better yet, take it off, and turn the water on at the faucet. I bet it spits out pretty fast again. Considering your camper sat for some time, it's possible the screen rusted over and then gunked up. Or, the higher pressure broke some crud loose in the plumbing lines, and it stopped at the aerator screen, causing a clog, thus a slow flow. Try it. See if that's what it is.

FYI, I just removed mine completely from my kitchen faucet. It ran slow all the time, from day 1. Taking it off, water flows free. The hole the water runs through is so tiny, it's a wonder any water makes it through. I think whoever made the faucet put a defective end on the faucet. So, rather than sweating over it, I just removed it. Done! Simple solution.
