Fresh water flush?


Recommended Posts

I'm going thru our new RV (well, new to us!) and I can't figure out how to dump the fresh water tank....the diagrams in the manual are not what I have...

I ha e been able to get the water pump to work on what's left in the tank (38%),  but I'd rather simply flush it quickly and refill to clean and prep for our upcoming trip.

Any suggestions?

Mine has an ball valve on the line coming from the tank.  It is just a gravity drain, so not much flushing going on... but it can be drained when you are getting it ready to store for the winter.

My coach has three water drains, one for the hot domestic water line, one for the cold domestic water line and one for the fresh water supply tank. Each one protrudes through the bottom of the coach so you can actually see them while laying on the ground.

The hot & Cold are on the passenger side of the coach near the Manabloc Water Manifold. The Fresh water tank drain is inside my service bay.

They all come with a dump valve. Some are mechanical, some are electric. All use gravity to drain. And unfortunately, every model is unique. If the manual is not available, or simply no help, try to follow the plumbing lines, starting at the tank.

On my 03 Windsor the fresh water tank is just aft of the diesel tank.   Mine has a bay door where I can see the tank.  On the drivers side I can lift that                                                                                                       (  propane  )                                                                                                                                                             door and see a valve down at floor level, that's my tank drain.

Are the hoses I circled going thru the floor and open underneath the coach?

I do....I see several blue pex peeking out from underneath....but there's no hand valves to release the fresh water tank...it's a solid cover underneath...so I've been running the water pump thru the 4 main pipes, kitchen, bathroom, shower and toilet...

The PO had some special things done to the coach, plumbing-wise, so I'm hunting and pecking to see what works...

At least I'm down to 32% fresh...but gray and black are still at 0%...will admit, I haven't put much down either pipe...at least the toilet holds water and the shower works whilst on WP and LP....should count my blessings...🙏

The drains in that bay are for winterizing. Your fresh water drain is on the opposite side of the coach by the dump valve. Look there for a knife valve. In the alternative, look under the coach below your dump bay..Item 21 below......Dennis

The first two are what I believe to be the fresh water dump....I'm afraid that valve is shot....trickle, drip, drip...😆

More pics!

Here's the temps for the NotsoCold...I must admit, I'm very happy, but we're also connected to 50A service.  When we picked up the coach from storage, the freezer was at 0° and the fridge was 34°.  👍🤗🥰

We did throw a ton of product in there, so it's probably still adjusting....at least the beer is cold. 🍻

Any threads about checking the leveling jacks not retracting?  I might be here longer than planned!  😆

Congrats on figuring some stuff out and feeling good.  Now time to replace that ball valve.  I have not had leveler trouble, but you should be able to find a manual online to troubleshoot.  For mine, check fluid when retracted.  I know there are fuses, maybe yours blew?  Check the grounds, is there voltage going to them, etc...is the switch good?

Steven,

Good idea!  I'm researching the seal for my Sealand Toilet, Model 511, as it no longer holds water and I need to lubricate the Weiland rabbit ears (the inside handle broke attempting to raise it 😖), and I'll be crawling under the coach if the leveling jacks fail to retract tomorrow morning...😆

I'll keep y'all posted!  👍

Two things, Eddie. One Shark Bite fittings available at your local Home Depot will correct that ugly piping. All fittings are plug and play and very simple to install. Ask one of the aprons to demonstrate. The other thing and it's a BIGGIE.....Crawling under a coach without proper blocking, especially playing with your leveling jacks is a recipe for disaster. The coach will drop faster than you can crawl and be lower than you are thick, so make sure you use proper blocking before crawling under there poking at stuff.....Dennis

as a follow up to the Shark Bite fittings and how great they are for our coaches........here are pics of a project I did in 2018. No more leaky Manabloc, replaced with custom copper manifolds. could not have made the change without Shark Bite fittings. The crimping tool would not fit to crimp compression rings in the confined space. Malcolm
