So you are saying to yourself  why do I want to DIY this type of project when I can just go and buy one of these, RV Water Filter

The answer is, that once the big blue filter is put together, you can get two of the filter replacement cartridges for big blue for less than one of the above filters.  Also there is the chance of bacterial build up because, unless you are a full timer you are not using the filter enough.  With the replacement cartridges you can just take it out and throw it away and use a new one next time you go out and you will still be saving money.
But wait there is more.
What if we add a second big blue filter?  Would we gain anything?  You bet.  So let’s do it.

Sediment Replacement Filter

A sediment filter gets rid of: sand, silt, dirt, rust particles and scale particles The park water should come into this filter first, then go through the Drinking Water Filter with Carbon and finally into your rig.  So now we are done right?  Not so fast RVer slow down and keep reading.

The Triple RV Filter
With this type of filter system you have the best possible filter system for still not a lot of money.  So what do you need?  Everything listed above plus an additional 3/4″ Brass Nipple of the correct length to go between two more blue filter canisters.  Plus one more special type sediment filter the Special RV Filter which looks like this,

Special RV Filter

This special filter goes just before the Drinking Water Filter.  I know this looks like a lot of work but it really is not.  It is just a lot of hooking up of pipes to plastic.  You will need some Plumbers White Tape which looks like this,

 

Mounting the filters
You can use a 2″X 4″ (2×4) of the length you need and mount the filter holders to that as a way of keeping them corralled together or you could mount them in one of the service bays on the rig. It is up to you. The water you will get from the triple filter has to be drunk to be believed.  This system will not take pond water or salt water and make it drinkable.  This will however make city treated or treated well water taste just great.  And the wife’s ice tea will be out of this world.
