Try running a bath, it's like being at a public swimming pool.

 

 

It smells like that from just filling the bathroom basin.

 

I'm tempted to save a couple of hundred and install this and just use the Puretec filters in it.

 

Can anyone advise if I can use a washable super low 0.35 micron sediment filter in stage 1 followed by a higher 20 micron carbon granule filter in stage 2?

 

It sounds counter intuitive to have the lower micron filter first, but does the micron level of the carbon filter even matter at that point once it's already gone through the sediment filter - isn't it then just for taste and odour removal?

Glad to see this thread is still open (I'm considering this for a new build) but I'm curious to know how this affects your water pressure assuming this is installed to filter the entire house. I'm not sold on needing to filter urban water but the SO is slightly obsessed with it so here I am...

 

I'm looking to pair this with a natural gas hydronic heating/hot water system (something like the kit centralheating.co.nz sells) but would also like the option of a rain shower head in one of the bathrooms. These can require a decent level of water flow and I understand there can already be capacity issues with combination heating/hot water gas boilers so I'd be interested to hear if anyone here has one of these filters installed and if it has significantly slowed your water pressure?

With the big system that I put in (wh2-60), water flow wasn’t altered. I think it’s up around 50l/m. If I changed to a .5 micron cartridge it would alter it slightly. The smaller system wh2-30 would alter that flow. But what the numbers are, I’m unsure.

I was also interested in doing the whole house filtration system. Which company did you use and which model did you go for? I am based in Wellington as well.

I went for a puretec wh2-60.  You just buy from Mico etc, and have a plumber install it.  It was about $500 in parts....as opposed to a "water filtration company" suggesting it would be $1500-2000.

Thank you that's great. I had similar quotes of $1000+ from water companies. 

 

And you mentioned that you didn't notice any drop in the pressure? Because the instant hot water system will require adequate pressure to work....

 

This is very useful information thank you.

No not really noticeable.  I'd tried measuring my water flow (bucket + time) and worked out that mine was about 50lpm where the -60 is supposed to be at 60lpm (the -30 is 30lpm)

 

So concluded I shouldn't notice.  I also have an infinity system.

Ah, excellent. 50-60L/min should be ample for what I'm after. It still depends on what the actual flow rate from the street of course but good to know a filter is unlikely to affect flow much. @davidcole how often are you replacing the PureTec's filters. This is one of the units I was looking at too since you can pick them up from a lot of stores.

The first one was quite quick...like 4 months which was concerning...but all my garden taps are behind it, and I'd water blasted all my courtyards.  The current one though has been longer.  Like i'm at the 4 months now I think.  They're not cheap....but when you replace the sediment one and look at the condition of it, you're glad you've got it in place.

It might be worth pluming this in a little down stream, or installing a new tap further up stream, so you have access to unfiltered/untreated water for garden purposes.

Flow rate is usually based on area, so the bigger the cartridge, the longer you can go before you clog it up and the flow rate is impacted.

 

Often too hard to do afterwards, but longer term having your toilet (or select other areas like /laundry/dishwasher etc) fed with chlorinated/chlorine residual water isn't such a bad thing.

Yeah I'd probably recommend that also.  Depends how quick from the toby everything seperates.  Mine is pretty much as soon as it enters the property.

True, this has been my point. I can see why someone might feel like filtered drinking and even shower water but I see no issue with chlorinated water in the toilet and definitely gardening water should not need filtering.

 

My place is still a new build in the planning stages; in your experience is it likely to be a huge pain in the ass/expense to have the plumber split off the outdoor and/or toilets before the filter? I feel like the pipes feeding the bathrooms would need duplicating for the toilet which is just wasteful.

I never had it done.  If you're doing a new build, surely you just mention it to the plumber and say which outlets you want filtered/not.  Like it's only really the outside ones you'd realistically split off and run a seperate water circuit.  I doubt you'd bother with anything, other wise you start getting to the just put a filter on the kitchen bench.

One filter is installed for Washing Machine (Bosh). From time to time error #3 (Low water pressure) pops up. Small filter inside "Aqua Stop" is clean and all cloths is white as rust is filtered.

In our current place we put in a 2 stage system. A sediment filter in stage 1 followed by a carbon block filter in stage 2.

 

We are now in the process of building a new house and we are definitely wanting a whole house filtration system again.

 

I often here you should have a KDF filter as well, but none of the whole house systems seem to have this?

 

Should i have a 3 stage system? Sediment --> Carbon Block --> GAC/KDF ?
