Water filter

[Bacchus]

I have a 2017 Shamrock 21ss and last fall while winterizing it I took off took out the water filter so I could put antifreeze in and in the process water went everywhere. I am now ready for the reverse process, does anyone know how to take the water filter housing off without getting water everywhere?

You're pretty much going to spill water every time you take out the filter (when it is full of water). I put a towel underneath it and am careful to limit the spilling, but you can't prevent it.
Some people have moved their filters to the outside to eliminate the problem.

I was afraid of that, but I knew if were was an answer this was the place to look. Thanks for the info.

I just blow out the lines first using an air compressor, that empties the filter housing some so it's not right at the top.

Also, to avoid having to fill it with antifreeze, I got some PEX valves and installed a winterization bypass around the filter. Now I just blow out the lines, switch it to bypass, take the canister off to empty the remaining water, and then run the anti-freeze through the rest of the system. Not only does this use way less antifreeze, as an added bonus, I found the water pump primes much easier when pulling the antifreeze in this way.

For what it's worth, I have the same problem with my larger home water filter. It's not necessarily a problem with the TT, but the design of that type of water filter. Can't move the cartridge without spilling a little. Just dry it up afterwards and it won't be a problem.

Too bad they aren’t designed with a petcock on the bottom like the fuel filters and raw water strainers on my boat.

I usually put a small plastic bucket under the filter to catch the water/anti freeze in. Works for me.

If yours is like mine your filter is in an inaccessible place hidden from view.

1. to make it easier just make a bypass of the filter by cutting the IN and OUT lines and slicing them together.

2. get an outside filter that you throw away every year or more often if you like... get them at Walmart for about $10

3. bypass and eliminate the hidden filter and eliminate a possible problem of having the water filter leak, soaking your floor in a hidden spot.

Just get rid of the filter and use a outside filter

one reason I got rid of mine was it was a pain in the backside to drain the water each fall in doing so you get water all over . some water got into the fuse for the water pump which is right under the filter. Rust soon set in and water pump stopped working so I changed the fuse and fuse holder and use a outside filter.

^^ What he said ^^

I did this 3 months into our new fifth wheel and haven't looked back.

By outside filter do you mean one that hooks on the end of the hose you use to fill the freshwater tank? Also wouldn't that leave the water from the fresh water tank unfiltered?

Use the same filter on the hose when you fill the tank.

When I winterize my Roo, I take the filter out, and I put an empty plastic water bottle (sealed) in the housing. That saves on how much antifreeze fills the housing. The 2nd benefit is when I remove the housing to put the filter back (which I just did yesterday! ) the housing is only half-full with water (the bottle floats on the top) and so there's almost no spillage of water.

[Bacchus]

Thank you, that is a terrific idea. It is especially helpful because my filter is located almost on the floor, about two inches.

Question for the folks using the Outside water filter.

Is the filter before or after the water pressure regulator?

Seems on other threads people complained that the external filters reduced pressure to undesired levels. Logically it would seem to insert the filter prior to the regulator, but I am not sure if that is asking for problems.

Thanks!

It gets filtered when you filled it. It makes no difference before or after. Mine is at the hose bib.

I always put a big towel down for anything that involves water. Have a shop vac near me to clean any running water. Some folks have a method to back syphon the water filter canister water down to a manageable level when you pull the filter canister.

Not just a good idea, a great idea.

Sorry friend I must steal that idea and use it myself. This is an outstanding idea for all rigs.
Thanks
