Question on Land Yacht systems.

Hi there,

I just bought a used Land Yacht and have only camped one night in it so far. I'm new at using an RV and have a question about the systems used to drain the gray and black tanks.

On the bottom where the sewer hose attaches, there's a faucet on the right and a female hose attachment on the left of the sewer hose. Is this a built-in tank flushing system? Does anybody know how to use these hose attachments and faucet?

BTW: I do have a manual but I just got back home frm where the RV is parked and forgot to grab it <again...>. I'll try to grab it next time I go to the MH. I suspect it's a flushing hookup or something like that.

Thanks for any advice.

Don't know about the faucet, but the hose connector is to help with the cleaning. I've seen two such devices. One uses the incoming high pressure (potable water) system as a jet pump, sort of a venturi effect. The other type actually "sprays" clean water up into the valve area, thereby facilitating solids removal.

If you can't remove the valving assembly (it may be an "add on" spool installed on the original hose connection) for a visual inspection, perhaps at the next cleaning you could use a mirror to ascertain the internal flow arrangement.

An inspection of a "new" add on spool available at most RV accessory stores may help to understand what to look for.

the faucet is for washing your mh or watering the flowers. just consider it the same as a faucet on the outside of your home!

the female fitting should go to an internal tank flush system. i have one on my trailer, sure is nice!

get your manual and study up!

Low point drain...

The faucet is also a low point drain for your plumbing system. You can open it to drain the water from your pipes before you blow them out for winterizing.

(just got done typing a reply and lost it all somehow....grrrr)

Thanks a lot for the explanations. It's nice to have a flush system built in. And I suppose I just open the sink faucet and the outer faucert and it drains out.

I'll go get the manual and study. Will be back later.

Thanks again for the help!
