No Water at Kitchen Sink

[dwdlt]

Good morning All. I hope everybody is safe and COVID free. I made a rookie mistake this year and burnt up my water pump. I changed the pump (exact same brand, type, and model) and now I only get a trickle at the kitchen sink.

I get good water pressure everywhere else, and I'm pretty sure I have all the air out of the system. I unscrewed the filter screen from the faucet already, and it was pretty nasty. changed that out.

I'm thinking it is a check valve that is bad, but wanted to check and see if anybody has any ideas.

Trailer is a Keystone Laredo 314re. It's a 2016.

Thanks for any help or suggestions.

How long did you let did you let the pump run? I'm guessing that the kitchen sink is at the end of the run. Filling the water heater and the lines can take a min. or two.

There probably in no check valve in the water system. By "no water at the kitchen sink" I suppose you mean hot and cold sides ?? If so, and if there's no water flow with the aerator removed from the faucet, then I'd guess that you've got some "failed pump debris" that flowed through the lines and is "damming up the inlet connections" on the bottom of the faucet valves.

As Marshall indicated, it takes "a long time" for water to flow through the entire system, so make sure to "just let it run" for a couple of minutes before "tearing into things to clean the valve seats."

I let it run for a quite a while, but never got much more than a drip.

Yes, both hot and cold. I did let it run for a bit, but not much more than a minute and a half. So, I'll go back out today and let it run for a few minutes or so.

Thanks to both of you for replying

Maybe a sill question but you do have sufficient water in the tank and the batteries are charged? Pump is not in "winterizing" mode? My pump has a hose on the inlet side with a two way valve so that it will draw from a jug. If the valve isn't fully turned then the pump will suck air and not prime.

Thanks for the reply. All that is good. tank is full of water, and the valve on the winterization kit is in the correct position. I have full water pressure in the bathroom sink, shower, and the toilet, but just nothing to the kitchen sink

Is that sink in a slide out?

[dwdlt]

No, it's in the center island. But, the trailer does have the super slides on both sides. Not sure if that makes any difference, but in case you are on to something, I wanted to mention it.

[flybouy]

If the sink is stationary then there shouldn't be any separate valves. The low point drains are closed or capped off?

Gotcha. the low point drains are closed.

Unscrew the lines under the sink and see if you get good flow there. You say the screen on the faucet was nasty. There might be something plugging up the faucet.

[KimNTerry]

This happened to me and drove me nuts. I loooked at eveything. DW removed the aereator, lo and behold the flow improved.

Try removing the aereator from the faucet. If it gets flow without the aereator, then clean or replace it.

Just another item to troubleshoot.

How long have the temps in your neck of the woods been above freezing? Island kitchen plumbing can freeze up easily and be the last to thaw. Don't ask how I know :hide:

Well, you were on the right track for sure! :) I did just as you said, and I have plenty of pressure to the faucet itself...oh yea! I took the faucet out, and the main feed line is pluged up tight as a drum... All kinds of crud in it....

I'm ordering a new faucet now.

You can remove the valve stems, clean them and the faucet "mixer channel" and reassemble. That'll give you a functional faucet until the new one comes in and you find time to install it.

Sounds good. Thanks

Feed line you mean the water line? Why change faucets if the water line is plugged... am I reading you wrong?

[Pmedic4]

We had the same issue, of course my first thought was like your, water pump bad - I had just filled the FW tank. Every other faucet worked fine, except the sink. Took the lines off the faucet, and flow through those was good. Aerator was plugged, cleaned it and have water now. Doesn't seem as good of pressure, so I need to investigate further, but definitely the sink faucet being plugged up.

Now I think I'll need to check all the other faucets and shower, because there was a lot of junk in the sink screen.

This is the flexible line, with the weight on it, that goes to the faucet and provides water from the mixing channel of the faucet to the faucet head....And, I'm probably using all the wrong terminology!

I took the faucet apart and cleaned it as was suggested by another member, and it was full of crud, and what looks line plastic shavings.....

I guess I could reuse the faucet and just change the line, but I just chose to change it out and be safe with it.

Yep, I'm doing the same

I would suggest flushing the line thoroughly before installing a new faucet. I'd be frustrating to do this all over again in the near future.

[JRTJH]

You said your water pump failed and you replaced it. Those plastic shavings may have come from the fresh water tank (drill shavings from Keystone installing connections to the tank) or they may have come from the diaphragm in the water pump when it failed... Either way, there's no "filter to stop shavings" from going to all the other water outlets. So, the bathroom faucet, the toilet connection, the shower faucet and the outside shower/kitchen faucets are also "subject to those plastic shavings"....

While those faucets and valves (in the toilet especially) may be "flowing great" right now, if you get a piece of plastic in any of those valves, you may wind up with a failure when you least want it... like the start of a long 3 day weekend when the toilet won't flush or won't stop running....

I'd suggest that since nobody is traveling or towing right now, if you've got time to clean the rest of the faucets, now is a great time to prevent future problems.

[flybouy]

Also, if you primarily using the fresh water tank I'd suggest using a filter to fill it and installing a screen on the pump.

If your pump is a FloJet pump with the blue "locking tabs", this is probably the "wisest investment you can make. Easy to install, reliable and stops all of the "plastic shavings" in one place before damaging the water pump diaphragm or clogging up the faucets....https://www.amazon.com/Flojet-01740300A-Pump-Mini-Strainer/dp/B004BC6E2Q/ref=sr_1_3?dchild=1&keywords=flojet+strainer&qid=1586453363&sr=8-3

If your water pump has the screw on fittings, you can buy this one and cut the 1/2" FW supply line to the pump and install it "before the pump"

There are alternative filters available. I'm not endorsing either of these products, but I have the "blue locking type" on my FW system. It's 6 years old and never a problem...

[bbells]

I hear this one all the time. It is a simple fix. Unscrew the aerator at the end of the faucet and clean it. You will now have a good flow of water.

The OP cleaned his aerator and then installed a new one on the faucet
before even posting his thread. It didn't work. The clog was under the faucet, in the small hose that goes from the mixer valve to the faucet throat.

Cleaning the aerator is a "good first step" but he's waaaaay beyond having done that without any improvement in water flow. His problem was "under the faucet, not at the aerator.

You can use a standard home store flauset if you change out the supply hose ends. If you don't have the crippling tool . Shark bite fittings work they are a little pricey but worth it.

I have the lower one and also 6 years. It has filtered out a dead pump and a dead water heater. Water heater left enough rusty crud to need the lines upbto the filter flushed but nothing got through to any faucets.

Yep, I have exactly this problem. Anyway, I just replaced all the system. (btw, it was pretty ild and it needed replacement).

Alermon32, This thread was last posted to in April. Not sure any of the originals are watching as most haven't been on the forum for quite awhile.
