We had a similar problem last summer with our fresh water tank not draining. Discovered a mud dauber had plugged it up. Took a wooden dowl rod and rubber mallet to unplug it.

You need to use the fresh water tank drain to drain the tank itself. The low point drains drain the water in the water lines. When using them you need to open up a hot and cold faucet to vent the lines.

Low point drains do not drain the FW tank. There is usually a valve at the tank to drain it.

Sorry Bob, didn't see your post. You nailed it.

ok, I'm lost, We have a 5th wheel silverback, the only valve I see i have is "city" and "gravity" I used Gravity to fill the tank but now i want to drain the tank, (i'm a new camper and this is our first rig) I am also still hooked up to my house (City) water do i need to disconnect then will it drain?

We are "camping in our yard to learn how to work everything

Thank you

[kevin211]

oh and the underbelly (frame) is enclosed

[kevin211]

ok i did notice at the friont of the coach i have another set of low point drains these have "caps" on them would these be the ones to drain the tank?

I can't see under your unit from here but my fresh water tank has a pipe/tube coming straight out the bottom of it - centered side to side of the tank but closer to the outside end of the tank. That pipe/tube on mine has a cap on the bottom end - no valve. I have to take a knee and screw off the cap (and retain the rubber washer). I usually open the fresh water gravity fill cap to allow air in faster than just the vent tube.

Can you find your fresh water tank? I'm guessing it's right below your gravity fill.

Mine is below the fill ... a tube with a valve ... back of 5ver ... no where near city hook up or flushes they are in side storage pass thru

My fresh water drain is right below the tank on the underbelly. Looks like this

Yep that's what mine looks like, I ended up putting a metal rode up thru the opening and found it was blocked, now we are draining..... now do i trust to fill it up the whole way to see if the overflow vent is working...lol

Thank you to everyone that help me....

Tell us what kind of unit you have.... motor home, 5th wheel, bumper pull? And what kind is it?

You should be good to fill now. When we have been filling our fresh water tank at the gravity fill sometimes it won't take water in very fast, and will spray back even though it is far from full. The problem is the screened vent is clogged. I remove the clear tube from the Camco water tank filler and blow on the screened vent to clear it. Works every time. Hope this helps!

I know you resolved your fresh tank drain issue but I don't believe anyone addressed this question.

These are your low point drains for the hot & cold plumbing.
You mentioned low point drain when describing your fresh tank drain in your original post but I'm betting you were referring to your tank drain then.

These often colored blue/red lines (not always) with the caps are your actual low point drains as they are called in the R/V industry.

I put valves on mine to make draining easier.

I find that my tank drains faster when I open a cold faucet.

Low point drains will not drain fresh water tank. There should be a pipe comming thru the underbelly just below the fresh water tank. My experience is most come from factory with a scew off cap on the end... Some replace this cap with a valve for easier use. Remove this cap to drain Fresh water tank.

Oops.... already solved I guess

Opening a faucet should have no effect on how the fresh water tank drains.

Unless maybe if the check valve has gone bad in the water pump.

It will, however, allow the plumbing to drain faster.
