Foamy Water at Kitchen Sink

I have a new 2015 Bus 37AP and every time I turn on the cold water at the kitchen sink the water comes out foamy for about 20 seconds. After the foam clears up the water comes out normally. Anyone else with this problem and if so what's the cure?

Thanks, Sammie

Could it be air in the line or some left over antifreeze ?
Are u on pump or shore water?

Do yourself a favor and sanitize the system. Clorox will clear out any residual antifreeze or most other things that might get in a water line.

It's more likely that it is the water supply than anything else. Depending on what I'm hooked to, it will do the same thing. Just let it run until it clears up. My own water supply will do this and I'm connected directly to the house soft water system.

Foaming is an indication of pink antifreeze in the lines.

Foamy Water at Kitchen Sink

Previous threads have indicated what's been posted here. Pink Antifreeze.
Best of luck with the new MH.

Foaming water

I have had the same foaming water in my bathroom sink for 3 years, this never happens in the other sinks. The foamy water is only there when I first turn the water on, and quickly goes away. This fresh water tank has never had pink antifreeze in it, and has been sanitized and emptied every 4 months for the past 3 years.

It has to be something else.

If it bugs you too much, run bleach through your system. That normally clears mine up.

BTW, my water system has never seen RV antifreeze so I doubt if that is causing any foaming.

Mine will do that on occasion. I remove and clean the aerator on the faucet and it clears up. Give it a shot.

Just re-sanitized with clorox, changed all the filters, cleaned the aerator. The foaming still continues for a few seconds when I first turn on the bathroom sink. Never had anit-freeze in this system.

Foamy like soapy or foamy like heavily aerated? If the bubbles last a bit like dish soap I would suspect a chemical problem like anti freeze. If there is just a lot of short lived foamy water I would be looking at the faucet design. Many faucets let a significant amount of water drain out of the spout when turned off. When turned on the air in the spout super aerates the first bit of water. Looks interesting but is not a problem.

Nothermark,

Thanks for the reply! You are the first person who has come up with an idea that may just explain the reason for the effervescent/foamy water at my kitchen sink faucet. It happens when I first turn on the water after the faucet has been off for a few hours, but only lasts for a few seconds until it clears itself and then runs normal clear water. Doesn't make any difference whether I'm on city water or pumping from the tank. I have sanitized the water system. Installed a different water pump (thinking maybe the OEM pump was sucking air).

This happens only at the kitchen sink faucet, so it does sound like the faucet is the culprit.

Thanks, Sammie
