Thanks to Hoglou on another thread, here is a picture of the plumbing. Top blue is city water feed. It has a tee with the output of the pump into the water filter. Next blue line is from the fresh water tank. Notice it has a tee in it. One side goes to the input of the water pump. Other side is a drain--notice the valve in it. Red line is the hot water line low point drain. Blue line on the right side of filter is feed to all water lines.

Here is a picture of the modification I made to mine to connect a line to an antifreeze bottle and have the pump pull antifreeze into the system. (Remove water filter first).

Makes sense. So, where is your cold water lines low point tied into the holding tank drain?

If these are your only drain lines I suspect that you will find the red line is actually the cold water line low point drain and not hot water low point drain. You do not have a hot water low point drain (accomplished via the water heater draining or by-pass valves set to by-pass) as previously noted. Just a guess.

RvBill fits the bill

RvBill,

You wouldn't have the part number for that brass AF pick up valve would you? I need to rework my plumbling in the filter area as it looks like a monkey did it.

It is a winterizing kit from Camping World (and I am sure other places).

I shortened the white hose on the inlet side of the pump and added the kit. All parts were included, except I did change out the hose clamps for new ones.

RvBill3 - Unless your water pump is missing the "normal" internal check valve that keeps water from the downstream side of the pump from running backwards into the upstream side, you cannot drain the lines downstream of the pump from the freshwater tank side of the pump.

I'm not saying that the line you're showing ISN'T a low point drain (it may be a necessary low point drain on the upstream side of the pump due to weird hose routing, BUT I strongly doubt that it's the low point drain that drains the downstream side of your pump. I suspect you've got low point drains elsewhere in your system, probably close (i.e., below) your kitchen or bath faucets.

Without crawling underneath my Sunseeker and posting pictures, I can assure you there are no other drains under the MH except the two you can see in the pictures. Yet somehow, for two winters now, I have drained every bit of water out of the system (including removing the drain plug from the water heater). I don't pretend to know everything about the routing of the water system, but the OP asked about the fresh water tank drain and low point drains. These are the only two drains.

In order to add the antifreeze, couldn't you detach the upstream from the freshwater tank and drop that hose into a bottle of antifreeze under the MH and pump it if you didn't want to add the bypass valve to the water pump or is that line buried?? I haven't dragged the coach out of storage yet.

I'm attempting my first winterizing try this weekend and that was my brother's suggestion to save money and mods on the pump lines. Although they look pretty easy to do.

Respectfully these are the way newer Sunseekers are plumbed
Two low point drains
Blue cold (shutoff valve in compartment by pump)
Red Hot (cap under coach)
Read the thread titled What came out of my hot water tank
It talks about my low point Hot cap breaking off and all the minerals and deposits sucked out of my hot water tank and staining the Aluminum on my Motorcycle trailer

My 2014 2450 has two drains.

1) Blue line from Fresh Tank with valve is the tank drain. It only drains the fresh tank.

2) Red line with cap drains the house.

Yours may be different....

trdutch: I'm wondering if this is really your FW tank drain, not a "low point" drain. (See MrJoe's item #1 in Post #19).
