Getting our new 2016 MBS 2401R prepared for the shake down trip and made a modification to the poorly designed water filter under the bed. Not only was the access very limited, you can't remove the filter without getting water all over the place plus it has to be removed to winterize. (the photo doesn't show how poor the access really is)
Removed the filter, cut the pex and bypassed with new piece of pex and 2 90's. (still need to remove some old parts)
For the new outside filter I took a new 5 gallon bucket and drilled two 2 1/4" holes on opposite sides. Put a quick disconnect fitting on the end with incoming water supply and male hose fitting on the other end.
Cut two pieces or foam pipe insulation about 4 in long that slides over hose and keeps the filter unit centered in the bucket.
I was never keen on the idea of filling our gravity water tank without filtering the water first. The bucket filter unit is very stable and allows me to fill the water tank with a 5 micron and charcoal filter plus soft water while at the house.
The bucket filter unit supports and protects everything plus catches all residual water when disconnecting and draining hose(s) and filter. Just pour off the residual water away on a tree away from the rv.
After disconnecting the regulator, Y fitting and small hose fit in the bucket.
