Winterizing - Plumbing Confusion

I bought my used 2014 Silverback 33RL July 2016. It included no useful documentation. This is my first attempt to winterize it. I'm going with the antifreeze method. I'm confused about two things at the present time. (There might be more!)

http://mypcpro.com/images/water-valves.jpg

The linked photo shows a blue hose with a valve on each end. I have no idea what this does. Any idea?

Also in the same photo I think I have located two valves for the HWH shutoff. Should there not be three valves?

Thank you all for your help.

I think I solved #1. It is probably for an inline water filter.

#2 still has me confused. I'm still unsure how to set the valves to bypass the HWH. Any ideas for only two valves?

Thank you.

Where does that white kinked hose go?

The kinked hose goes into antifreeze container "unkinked". The pump sucks the antifreeze through that hose.

If that kinked hose port is for antifreeze input it is not a WH valve. It's on the fresh water holding tank side of your pump and will not shut off WH input.

What do you make of the two valves? Could they only be to draw the antifreeze in?

Any idea how to bypass the HWH?

To me you have a very unusual plumbing interconnect and valve placement. I am not familiar with what you have and don't want to point you in the wrong direction and add more confusion for you. Someone with a unit like yours should chime in, hopefully with answers.

Here's a generic plumbing pic showing several versions of anti-freeze valving and hot water heater valving. Chances are very good that you look like some version of this.

Two valves for the HWH is OK if you have a check valve in the hot water line.

Only issue to me is the two valves on the same piece of pipe (your item #1). It makes little sense to have two valves in series with nothing tapping in between them. UPDATE - nevermind - I see the valve on the right is really a 3-way valve (assuming that white line coming up from the bottom is connected to it - it's hard to tell).

Ok, in your picture. (1) would allow flow in one direction or the other or no flow at all, not sure why. (2) shows the antifreeze input (as you stated) valve and a valve to not allow antifreeze into the holding tank when winterizing. With both of these as shown water from the holding tank would be pumped for use. I think you need to look behind your WH for any bypass valves (if they are installed). Without being able to physically check it these are only guesses. There must be method to the madness that created this plumbing nightmare.

As stated, that is not your WH bypass but rather your winterization port that will allow you to pump in antifreeze straight from the bottle. Your WH bypass is probably directly behind your water heater wherever that is.

I'm guessing you're right about the blue hose, looks like a connection for optional filter. The other two valves (with the white hose) controls what source the water pump will draw from. In one position, fresh water tank. Other position, jug of antifreeze. To prevent draw back, or siphoning, one valve open while the other one is closed.

Neither one of those are for the hot water tank. The valves are normally mounted right on / near the tank itself. Take a look at the other side of the convenience center (I'm guessing that's where your tank is), and you should see three more valves.

How do you winterize?

Water heater bypass valves are almost always right behind the water heater ( usually hidden behind a removable panel).

Remove as much water from he lines (air compressor 30PSI)as possible. Pour some anti freeze in the traps. Thinking about trying to install A Camco 35983 this spring. Hopefully the low wont get below 37-38º

Holy smokes! No valves? If you did no air and AF as I suggested that would cost you 6+ gallons of AF beyond normal and one hell of a flush come spring.

Glad you are on the ball.

In your pic #1 it would appear that the previous owner by-passed the onboard water filter. (it isn't a great filter in any case and is subject of numerous threads here) Your HWT by-pass and the shut-offs for your HWT should be behind the panel on the left in your picture. You need to open the bypass valve and close the cold water input and the hot water outflow valve to isolate your HWT before adding antifreeze. (Don't forget to drain your HWT!) The panel is easily removable as it is flexible and simply is behind an upright support if it is anything like my 2015 29IK. When you look behind the panel it's not difficult to figure out what goes where if you look closely as everything is color coded. The kinked hose on the right of your pic # 2 is to draw anti-freeze into your system (when it is not kinked) using the pump. In mine there is a small hole at the top of the left panel where this hose is stowed when not used for winterizing. It stays unkinked that way. The other valve in your pic #2 is to shut off the line to your fresh water tank. Close this when you draw in the antifreeze or you will suck antifreeze into your fresh water tank. Hope this helps.

Cheers

Winterizing - Plumbing Confusion

I really hope I did my winterization properly. We've got several straight days coming of high temperatures in the 20's and lows approaching single digits.
