New water filters

October 30, 2019, 05:25:56 pm

Got the dual canister water filter setup. And boy howdy, That slowed filling the tank to a glacial pace. The tank was filling so slowly that I thought I had a water leak on the fill side. Fortunately that wasn't the case. I tried blowing into the filter input side and I were a grunting to get any water to trickle out the carbon side.

.5

There ya go. That'll throttle down pretty much anything. Solid carbon block?

I think we generally run a 10-20 micron particulate and a GAC filter from rvwaterfilterstore.com.

Are you sure it is .5 micron, not 5 micron. That is a REALLY FINE filter.

Solid block and 5 micron sediment, Then a water softener. I figured there would be a slow down. But holy cow, These made a liquid traffic jam.
On the plus side. Our water will be wonderfully soft and safe. And If I turn my back for a few minutes while filling. It won't be a disaster so quickly.

Do you have a "sediment only" pre-filter of around 5 microns? If not, suspect the .5 one will clog up pretty quickly.

Yes I do Brett. I have a 5 micron in a double canister setup W/stand from the RV water filter store.

That's the kind of filter you want on your drinking faucet not prefilling your tank.

I thought it was good to keep Chlorine in the tank and filter it out for drinking & ice

Probably, But I hear of more folks getting sick from the untreated well water at some campgrounds than from their own tanks. I did a system chlorine flush using spa chemical. For our tanks, One teaspoon of spa treatment will kill everything. It has much higher concentrations of available chlorine than household bleach. And if one isn't careful of what household bleach they buy. You will also get fragrances and anti-splash additives as well.

For sanitizing wells, so I would assume same applies to RV water systems, you should only use Clorox brand standard bleach.
The perfumed bleach is not safe for drinking water sanitation.
Generic bleaches are generally not made with the same ingredients as Chlorox, sodium hypochlorite and sodium hydroxide and do not always sanitize as effectively.

We have the same system. Slowed us down some, but we didn't get super slow until we added an iron filter. Only really noticeable in the shower (but we run a very low flow shower head as well) and when filling the tank. We also run a salt-less water softener.... so we have a total of 4 canisters! Water is so good we may even ditch the Berkey! Or get new filters and store the thing for future emergencies!

I get the feeling that some folks think I was complaining/not happy. I was just curious if the flow rate slow down was from those filters. I'm not bothered by a slower fill, Being in a hurry and motorhoming is an oxymoron.

The only time I use tank water for drinking is if it's run through the coffee maker, microwave or water boiler for hot chocolate. Otherwise it's bottled.

I did the math and add 18 ml of Clorox when I fill my 88 gallon water tank. The under sink drinking water filter takes care of the chlorine taste.

We have spent quite a bit of time in State parks, and while on a walk I found one park's water tanks. That's when I began adding chlorine.

Schedules are for others.

But. If you want a higher flow rate from your sub-micron filter element, why not hook as many as you like in parallel?

I'm rethinking more water filtration set up in the coach. Like many I have the drinking water filter under the sink, as well as the prefilters on the inlet side. But want to increase the ability to filter from questionable sources. How many of you have UV lights on your water line? Which one?
How about RO systems? We have a RO at home for the sink. In the coach what happens to the waste water from such a system?
Anyone use the south of the border system from RV water store?
10 inch filters vs 20 inch?

I've run a whole house RO system on our coach for 8 years. I run 10" filters. One 10 micron sediment filter and 2 carbon filters through 2 RO 100 gallon per day filters run in parallel. It takes about 20 hours to fill our fresh water tank from empty. We also have a by-pass so that if we need to fill quickly at a water station it only runs through the sediment & carbon filters. Depending on the water fill station it's only 15 to 30 minutes to fill 105 gallons.

We love the RO. Our water always tastes the same. I'm very sensitive to water taste so the the RO system allows us to go campground to campground with no taste change in the water. We were just in Mexico for a month and drank our RO water with no issues the whole time. The down side is it takes a long time to refill. Not a big deal in a campground where we just let it run all the time. (it has an auto-shutoff) Only other issue is what to do with the waste water. I run it into my gray tank. It does require me to dump more often but in a campground not that big of a deal. I usually combine my gray/black tank via my 3rd valve. We almost never get any tank odor. You can also plumb into your sewer line and let it just run into the camp dump. If we are filling an empty FW tank or doing a lot of laundry or both I'll close the black valve and leave open the gray until I've built up the level in the FW tank.

I bought a system from RV Water Filter Store to start. I've added a RO pump to boost water pressure and added an Alkaline filter to put back show of the good things the RO filter removes.

There are several people on the forum with 10 gallon systems and only use RO for drinking water. Not really that much less expensive but much quicker to fill.

RO filters are just a membrane that has holes in it precisely sized to only allow molecules the size of water or smaller through. Water is one of the simplest molecules (H20) so is very small. All the bad stuff is much larger so doesn't get through membrane. It gets washed out with the waste water.

Filters use to be expensive ($70) but can now be picked up on ebay for less than $20.

Buying a 4 or 5 stage whole house system would probably be the best way to start. PM me or ask here if you have questions.
