Question Winterizing: bypass filter?

Hey, I'm winterizing my R-Pod 177. I ordered a Camco pump converter winterizing kit, but looking at my SHUR-flo pump, there's not much room on the vacuum side to install the winterizing kit's bypass valve UNLESS I take out the little filter that sits between the pump and the hose from the water tank. SO, my question is, how important is that filter? I guess I could take it out every winter to make room for the bypass valve and re-install it every spring--it's just hand-tight plastic screw threads. Other solutions?

I wouldn't remove the filter. Its important enough for the manufacturer to include it.

A few ideas:
Can you route the freshwater hose on the left under the hose behind it? That might give you the room you need for the bypass valve to fit between nicely.

You can also move the pump to a better position.

You don't need the bypass valve. You could just unscrew the input hose and put the antifreeze hose on. Then when you're done, put the freshwater tank hose back on.

Hope that helps.

All sound like good possibilities, Skip12. Thanks!

If I recall correctly, the Camco kit’s 3-way valve should be installed directly onto the input side of that small black filter/screen housing. Disconnect the white 90 degree fitting from the filter housing and install the 3-way valve between the fitting and the filter housing. Is there something in the way preventing you from installing it there? It’s hard to tell from the picture.

Thanks. Yes, the white foam insulation (top left of photo) is too close to that 90-degree freshwater hose fitting and can't accommodate the extra length of the 3-way valve. But when it arrives next week, I'll know for sure.

OK. If you canít get the 3-way valves to fit then moving the pump toward the camera and extending the hoses on both sides may be the only option to be able to use the valve kit.

cut the gray hose that goes into the pump and install the valve in the cut hose?

Here's what I did

Thanks everyone for your suggestions. Here's what I did, as a big freeze is just hours out. I replaced the inline filter with the Camco winterizing kit's bypass valve, ran antifreeze through the system (not the tanks!) and then took out the bypass valve and replaced the inline filter as normal. Realize this is an expedient solution and next spring I will attempt to move the pump a little bit further away from the hot water tank, so as to make room for the Camco bypass valve on the vacuum side of the filter. Phew.

MTsapphire, typically the water filter housing is downstream of the water pump so if you’ve introduced the antifreeze there, then your pump and that strainer don’t have any antifreeze in them and they aren’t protected from expanding water if it freezes.

Thanks, itat. In my case, the filter was upstream of the pump (between the water tank and the pump). The antifreeze went through the Camco bypass valve, into the pump and then into the various water lines and the toilet, with an extra dollop for the traps. Sure hope this did the trick!

MTSapphire, thanks for following up with your solution. Be sure the filter on the water pump is 100% dry since you didn't pump antifreeze through it.. You don't want water in there to freeze.

Thanks, Skip12. I blew air through it and dried all surfaces I could see.

Is this a real filter or just a mesh screen? Just curious. I'd not worry about a mesh screen.

We have a real cartridge filter in our Roo which will be completely ruined with antifreeze so I remove it and put a blocking plate at the top of the filter canister so as to not fill it with antifreeze and waste it.
