So you want your car to be shinny and spot free? Mr. Clean has gotten out of the car wash business so we have to take matters into our own hands. First let me say that this was not my invention, this came from NastyStang113, though he has a slightly different set up, which is what led me to this write up.
Here is my outside setup, you’ll notice the faucet does not lend itself to convenient use of a splitter, if you can use a splitter you can substitute that for the quick connects… but the idea is the same
So what you will need (Home Depot, you can substitute many of these with similar items):
1x reel leader hose (hose extension) $6.98
1x filter canister (GEXWHO4F) comes with a bracket but no filter $17.98
Filters: I got a 2 pack of FWTC rev 2, they remove sediment plus chlorine $11.62
2x Hose Quick Disconnect Sets (1male 1 female per set) $5.47 each [you see 1 set and 1 male in the picture because I already had a female at the house)
1x 3/4” to 1/2” Hose Adapter [3/4” FH x 3/4” MiP to Tapped 1/2” FiP (WATTS A-679 ]$3.53
1x 3/4" to 3/4" Tapped Hose Adapter [3/4” MiH x3/4” MiP x 1/2" tapped FiP (WATTS A-665)] $3.53
Some Teflon Tape $0.98
My receipt total was $57.63 after tax, but included a clamp I was going to use for a bracket ($1.83)because I didn’t know the filter came with a bracket (d’oh), and a $0.99 bag of skittles my 4 year old wanted. So if you don’t bring your kids you can save some money… Oh and I noticed Home Depot was nice enough to not charge me for Teflon tape
… With Logistics out of the way let’s get started.
First unpack everything make sure it’s all there.. open up the filters system
You’ll see the bracket, and wrench, you may or may not need the wrench, NastyStang113 says to hand tighten but I had to use the wrench, then again I have seriously high water pressure. Open up the filters, put one filter into the canister and tighten. It’s up to you if you want to use the nifty battery operated filter reminder, but given it’s based on time, it’s probably not valuable because you won’t be running water though this 24x7, the filter should last 3 months easy.
Next Teflon tape the adapters
Put the adapters and bracket on the filter
Place the bracket around the holes and then tighten them into the filter. The 3/4" to 1/2" (one with a large nut on it) goes on the “IN” side of the filter and the other fits onto the “OUT” side. You’ll want to use a wrench to make sure these are very tight, don’t over tighten, but they need to be in there good to prevent leaks
All set..good.. now the ‘complicated part’
You need a quick disconnect on the house faucet (female)
Quick Connect Male end on the leader hose, the other end of the leader hose will connect AND STAY CONNECTED to the “IN” part of the filter.
On the end of your everyday use hose, place a 2nd male connector: this is so you can connect directly to the house faucet or to the filter as needed. This allows easy switching from car wash to anything else. Again if you have the ability to use a splitter directly from the faucet it’s a good option.
On the “OUT” of the filter place the 2nd Female connector, again tighten with a wrench, but do not over tighten. By now it should look like this…
Now you can mount the filter, mount it wherever you want, it’s 2 screws you put them in and the bracket has a standard “bighole & slot” form so you can fit it over the screws and it will hang. For my set up I mounted it to my hose carrier, it works.
Now connect your leader hose from the filter to the house faucet quick connect, and your hose quick connect (male) to the filter quick connect (male) and clean your car.
A few notes, there is some noticeable pressure loss, if you need high pressure you simply have to leave your washing nozzle “off” and it will build up then when you depress the nozzle you’ll have a few seconds of high pressure. This isn’t a big deal since when rinsing you really want a lower pressure (mist or shower nozzle) held close to the car.
As for pressure build up, I haven’t tested this, but given this kind of set up you may not want to leave your water turned on with a nozzle connected and not being used for too long, I’m unsure as to the amount of ‘build up’ the filter and all the quick connects can take.. maybe someone else can chime in on that part.
We’ll that’s it.. buy a filter every few months or so (depending on usage), I know with normal RO/DI systems the filters that have to be replaced the most are at least 3-6 months, most last a year, and that’s constant use. With this kind of filtration I’m sure you can go at least 3 months from a filter. Unless you’re washing 3 cars every other day... you get the idea. And don’t forget a quality car wash, and it’s a good idea to at least wipe down the majority of the water after the rise.
If anyone has anything to add please let me know and I’ll edit, I’m by no means a ‘water guru’ just happened to do this after Nasty gave me the idea!
