Draining Fresh H2O Tank

Just Sanitized the fresh H2O tank & now draining - my FC 27FB 2015 has the white poly drain & 2 brass ones - can I use all 3 or do I just have to use the white one - that's taking forever.

Thanks,

Glenn

Have you checked your owners manual? You might also want to read the following thread FYI, although it concerns a different model than yours:

http://www.airforums.com/forums/f516...ns-142643.html

The brass drains are probably for low points in the water lines, which you definitely should also drain IMO, among other winterization tasks per AS.

The following sub-forum also has many other threads on-topic:

Opening a sink valve will help the water drain a little quicker.

What is a sink valve ? Do you mean just run H2O from the sink?

Right, just open any faucet to act as a vent.

Opening a faucet will prevent vacuum from trying to hold in the water you are trying to drain from the brass low point valves.

You should open all faucets, assuming you are actually starting to winterize the coach fully (not just the fresh water tank). Your owners manual should list all the gravity-drain steps to take, followed up by compressed air, removing HW heater drain plug, etc.

Open all hot and cold faucets:

-- galley sink
-- bath lavatory sink faucet
-- bath hand shower
-- outdoor shower
-- toilet flush valve and hand sprayer if so equipped
-- hot water heater pressure relief safety valve stem
-- etc..

Have you checked your owners manual and the various other winterization threads I linked for you earlier?

The two brass valves are for the hot and cold water lines. The plastic valve is for the water storage tank. I drain them all and leave them open whenever there is a chance of a hard freeze, even if camping over night or towing when the temperatures go well below freezing for several hours.

Ditto to doug's advice.

Doug do you have tank heaters? My old coach did not, so I am unsure how much protection they afford. Thanks for any advice you can offer.

Maybe it's just me, but I don't think opening a sink valve will help the FW tank drain. The sinks are all on the other side of the FW pump - so no air or water will go from the downstream devices back upstream to the FW tank. There's a check valve in the way.

To break the vacuum you would / should open the FW tank fill... assuming the fill isn't always vented.

The open sink valves (and shower) will definitely help with draining the hot and cold lines though.

No?

TheHandyDan gets the prize for the correct answer! While there is no harm in opening the sink faucets in the trailer while draining the fresh water tank, the check valve in the pump (if functioning properly) should not allow any air back in the tank. Fortunately, on the year AS the OP has, there is a vent for the fresh water tank adjacent to the fresh water fill opening. So assuming that the vent is not blocked, opening the white drain valve should drain the FW tank. And it can take a very long time to drain all 39 gallons of water!

The two brass valves are the low point water drains and should also be open to drain the water system prior to winterizing. I'm not 100% sure how the system is plumbed, but it would probably be a good idea to open the faucets inside the trailer when opening the low water drain valves.

Actually you are all so very very wrong

The quickest way to drain the fresh water tank is to have my eldest daughter take a shower. ( just one shower )
