Interesting. Assuming the DI lasts the same time each time, you get a better idea of when it is likely to go off.

Although I am now using my DI from the "soft" tap of my Harvey water system, so hopefully I should get a lot, lot more use of the same DI.

How many washes do you get out of one these before you need replace/refill?
Simple calculator here that has been pretty accurate for me

The total might be correct, but no way that I only use 5 - 7 litres of water to rinse. That is what - 30 seconds of hose use?

I only ever use a watering can to rinse, minus the spout so it reflects an open hose.

I tend to wash & rinse panel by panel in the heat, as I find I get better results. I've found by doing this I use significantly less pure water than whole car at a time. Not the cost saving as my time is worth more, but in warmer weather I find the soapy water drying on very quickly - I have no shade on my driveway.

With this approach, you can rinse a car with just a 10l watering can; never use the open hose as just more wastage then required IMHO. Flow meter will be an interesting comparison for me on usage.

Mark at raceglaze also runs morethanpolish & has been extremely helpful in determining technique, alongside advice.

I might give that a try as it is rather a lot of work getting the hoses all reeled out for the different taps. Don't think the X5 will be enough with 10 litre can, but filling it twice is still more economical.

I was driven by efficiency (laziness) with my watering can mission. So much easier than messing with pipes. Agree the X5 will be a challenge on one can given the size of it!

Let me know how you get on buddy. Will also let you know how my pressure reducing experiment goes!

That system looks interesting, do you have all your water run through the water system, or just specific taps? What ppm is the water coming out of it and any ideas yet on overall costs of running it? If it can cut out water spots all over the chrome taps then I'll be having a serious look at getting one :)

It's great,we've had a Harvey's whole-house softener for over a year, no limescale spots on taps or sinks and the shower screen stays clear. Running costs are effectively the cost of the block salt, we (3 people) get through 1 pack (2 blocks) every 2-3 weeks. The blocks are much cheaper if you have storage and can buy in bulk - have a look on eBay for 'harveys block salt' (the same size blocks are suitable for all the block salt softeners)

A jolly expensive habit but sure does make a difference. I found the ones I invested in for the detailing business I use to run ran out rather quickly, so the open hose technique and an air compressor were significantly more cost effective. Shame that's impossible in London!

RO water is £2.50 for 25l (according to my marine aquarium owning mate).Could I just use this through a watering can or mist it on with a pump sprayer?

I've been reading on dw that many people just dilute detailing sprays with suitable de-ionized/distilled water for a quick spray and wipe.

If you have a dehumidifier then I am told the water collected can be used in the same way.

Dehumidifier still rates at about 50 ppm, so it will stain still.

My Kinetico softener is the same concept as the Harvey's, but when I use my TDS meter, the solids are a high post filter as they are pre filter. Having red up on ion exchange filters, it is swapping the calcium ions in the water for sodium, hence the TDS is not significantly lower. I therefore don't think my resin would last any longer than putting non softened water into it....or have I missed something?

Taps, shower screen all spotless & the softener test kit shows soft water, so know the kit is working correctly.
