When we leave our trailer the water always gets shut off. Have seen to many people come home to find their trailer is flooded cause of a broken pipe.

Usually there are two valves. Recently I saw a photo of a water heater bypass with a three way valve.

Do you have three hoses connected to that valve? Of not look a bit more closely, there will be a short clear hose for antifreeze, and a valve where it ties into the main line between the pump and FW tank

Yup, you've got 3-way valves.

Much easier to use than multiple one-way valves.

If you look closely at the back of the water heater, you'll find a check valve that works in cooperation with the 3-way winterizing valve.

Enjoy! You won't be able to fill the lines with air when the FW tank is full of water. Nor will you ever have some really strange shower temperature fluctuations!

When you get the chance, mark the valve positions for "Winter" and "Summer". You'll save yourself a headache some spring or fall evening.

Unfortunately I'm a bit confused. I was told both by the Camping World walkthrough guy as well as a coworker that when hooking up to City Water, it would bypass the fresh water tank and you could just use city water pressure for everything.

According to my manual, though, that doesn't seem to be the case. Below are a couple of snippets directly from the manual:

********
"The fresh water tank can be gravity filled or pressure filled using the fresh water inlet (called city water)."

"CAUTION - Be careful not to overfill the fresh water holding tank. It can pressurize the tank, causing leakage and water damage and void the warranty. DO NOT leave the tank unattended while filling."

To use the city water fill
1. "If needed, sanitize the system".
2. etc.
3. Turn on water, open faucets, you'll hear air, etc. etc.
4. "The water heater will fill first, followed by the supply lines and faucets."
************

So hopefully I can explain my confusion - it appears the fresh water tank can be gravity filled or city water filled (I have both connections). The manual cautions me not to overfill the fresh water tank, but then fails to mention the tank at all when talking about the 4 steps to use the city water fill.

I have a pressure regulator, so I should be good to go with that. In the WATER HEATER BYPASS section of the manual, it shows a diagram of the fresh tank, pump, and water heater and talks about closing valves so that anti-freeze doesn't fill the water heater.

The diagram indicates a valve going to the fresh water tank, but nowhere else in the manual can I find mention of that valve.

So I'm a bit confused.

Let's say I go to the RV park and wish to use city water and pressure without filling up the fresh water tank:

Should I try to find the fresh tank valve and make sure it's closed, then open the hot water valves and use city water connection (and disconnect the city water hose when I'm not at the RV, per the manual)?
I have the exact same trailer, bought it a couple of weeks ago!

City Water: We just went camping this past weekend at a site with full hookups and and hooked up city water to the back of the trailer. Basically there's no need to worry about the fresh water tank whatsoever when you're hooked up to the city water. The water pressure from the city will force water through all the lines and you're good to go. When you open a tap(s) you'll hear/feel the air in the line come out, but eventually it'll only be water coming out.

The city water hookup won't fill the fresh water tank. I think the water pump blocks this from happening. The only way to use the fresh water tank is to fill it up on the door-side of the trailer with a hose. Then turn on the water pump to pump water from the fresh water tank through the system.

That clear hose under the sink is for winterizing. Turn the valve so that it's inline with the clear hose and you can pump antifreeze into the system by turning on the water pump (after putting the clear hose in a jug of antifreeze).

Fresh Water Fillup: When you fill up the freshwater tank with a hose (door-side of the trailer), if you fill it up too far, it'll simply drain out of the freshwater tank overflow lines (not the low-point drains, that's something else). In theory if you left the fresh water filler hose unattended with a high enough pressure, it could cause a problem, but if you stay around the trailer while it's filling, just shut off the hose when you see water coming out of the overflow lines under the trailer near the freshwater tank.

Water Heater Bypass: In 287BHSW trailer there are only two valves, not three as it shows in the manual. Turn these to bypass the Water Heater so that you don't pump antifreeze into the Water Heater during winterization. The rest of the time the bypass stays off so that you can use fresh water tank or city water to get water into the hot water tank to heat it up.

System Sanitization: We didn't sanitize the fresh water system and pipes first (water/bleach/flush/etc) before we went camping and regretted not doing it. We had a persistent taste of anti-freeze (since it was a brand new trailer) in the lines which I think was pulling from the non-sanitized lines connected to the fresh water tank. We thoroughly flushed the rest of the system, but it didn't help.

After we got home I did a full fresh water tank sanitization and that did the trick. Water tastes normal again.
