Hi All,
I need to buy a filter to remove sand and calcium that I can install between our bore pump and holding tank.
We only use this water for washing, shower etc, not drinking

Can anyone advise of a system that I can just walk in and purchase now, and one that I don't have to try and talk to the store people about as I am never sure if they understand what I want, (as I'm sure you are all aware).
Some pictures would even be a better help.
Thanks
Mick

I pump from the well to the holding tanks where I get most of the particles to settle and then pump to the house/pool through a 18 inch two stage filter.the big two part blue long units.if you filter before the holding tanks you will block the filters very quickly and be replacing the often.after say one year/6 months I clean the sediment out of the holding tanks.so I'm actually using the tanks as what's known as a gravity filter.the second 2 part blue tubes is known as a mechanical filter.got the filter from do home.6,500baht.remember to fit it the right way around and it isn't for drinking.for that you need a 3-4 stage bio filter or what's known as a reverse osmosis filter.so from well to tank,tank to pump,to filter to house.i also use two holding tanks as I need a lot of water and the first tank catches most of the larger particles before going to filter.

Thanks Marco,
Good advice about putting the filter after the tank.
Obviously your pump pulls the water through it OK?
I will look at doing the same.
I will check out Do Home as well.

Mick on another note, how do you regulate the water level in the tank.

You have introduced a tank to the circuit. You need a float switch to turn the bore pump on automatically to fill the tank when water level drops?

The main pump to the house will have a pressure switch to auto operate when you open a tap etc. You may also need to have a 2nd float switch to stop the house pump so it doesn't empty the tank and run the pump dry. This may be covered by the bore float though which will keep the tank full. Maybe someone can turn a tap on and forget, like a little toddler you may have walking around now.
Just thinking aloud mate and you may have it in hand.

Hi Barney,

The mother in-law tops it up maually every day.
She's cheaper than a float And very reliable, believe it or not!!!

I have looked at the float options and will install later.
At present, the setup is very basic, but I'm about to get a slab poured and then start putting everything in place, including rain water tanks eventually.
Once I'm able to secure everything permanently, I will do it properly for the long term.

Thanks for your input mate.
Obviously, your job pressures aren't too bad

Also get the pump a filter near to the house as poss and you'll get better pressure.the pressure from the tank to the house pump should be enough less you open too many taps at once for too long.my well pump goes to a ball cock in the tank.double tank up if you think your going to use masses 2,000lt watering the garden.dont bother filtering outside taps either,waste of time and filter cartridges.

Marco,
I went to Do Home, but could not see anything like what you describe.
Maybe I was looking at the wrong size filters.

Can you send a picture of your setup and brands of your filters?
Thanks
Mick

there about 20 inch high.deffo do home but that was 18 months ago.its quite a common filter I had one in the uk.

Ok, great.
I thought they were much bigger than that.

So, this sits between your tank and pump, so your pump sucks through it?
Mick

No tank to pump,pump to filter,filter to house.search eBay for this.read description.

hi mick , i have been living in the forest (baan noak) for a while before and the well water in udon area is a problem , rich of iron (smelly water like rust water) and rich calcium , what isn't improving the lifespan of some tiles , faucets, or glass materials , so long time ago i did put 2 big stainless filters in between , one with activated carbon , takes away the smelly water and one with raisin , to lower the calcium levels , i do not think the 2 blue filters (too small)will do the job as you also have a sand problem , and the raisin filter in my case could not handle the amount of calcium in the water , my carbon how ever was ok , if your water isn't smelly maybe better a sort of swim pool filter to retain the sand ? , the calcium in the water is no problem for showering ..enc.., maybe look on the net how to a make diy filter to retain sand .
our system was well-pump ,to pump water true the filter into plastic floor tank, and other pump to bring this water to the home , any direct well-filter-home system will seriously result in pressure loss ...do not forget , bigger filters need frequently backwash and changing filter media what isn't really cheap...so maybe swim pool style filter? ...good luck

Thanks Kopkei,
Yopu are correct, I can not put the filter after the pump.

I just cleaned out the tank and only a few milimeters of mud in the bottom after two years use.
So sand is no probllem.
Our well water is really clean and clear, but calcium is my main problem.
So, what do you suggest and can you send pictures, brands etc?
Thanks
Mick

P.S. Barney, if you are reading this, what do you reckon?
I forgot to take notice of your setup at the times of my visits.

FWIW, I've used filters from these people in the past, including for my condominium building in Massachusetts in a city which has questionable water. The water comes out crystal clear (i.e., not even any residue left on the shower glass) and completely drinkable. They have various models, depending on how bad the water is, right up to water with small twigs in it. They do international. http://www.aqua-sun-intl.com/.

Sorry I was only thinking previously of how the water circuit would work.
The capacity of the flow rate required at your end socrce will determine the type of filter required. Small filters like marco has suggested are ok, but may need cleaning more often, but a larger flow rate will require larger filters which have backwash capability.

My GF is just setting up the new house filters and tanks now, I was going to post photos and info when I got home.
She ended up buying the Mazuna brand filter, fiberglass, stainless is available but more expensive. There are quite a number of brands around, not sure of their real quality, we have purchsed 2 filters required working in tandem exactly as Kopkei has described. Was about 21,000 bht for both. 1 does the carbon filtering and the other is for a more finer filter process. Near enough the same size as an oxy bottle. I think for your purpose 1 carbon filter may suffice. You can always add another later. The pump will suck , but being a PC type of guy I'll say draw the water through these. They have a manual backwash valve on the top. You can go fancy and get filters that auto backwash electronically I assume when the pressure gauge shows a set restriction to flow.

Get a sample of your water straight out of the bore via the pump in a white bucket and see how dirty it is. Let it settle over the day. Then get some clean drinking water in another white bucket, you may be surprised when compared how much sediment is actually in your water. What looks clean may not be clean once the 2 are compared. Remember as stated by others you are trying to protect the plumbing and taps from crap as much as anything else.
Goodluck Mick

so if the real problem is to much calcium in the water , i think you will have a problem to solve this easy and economically ,now we are using city water , with a small 5way uv filter under the sink to make it potable...
what i would do in your case is, a try to adapt the items that are in direct contact of this hard water to withstand the bad influences , for us no problem ,(non potable home use)or you can try to use the double filters ,(like the biggest one barney posted , not smaller)if the water has no smell only raisin filter for the calcium , but what they forget to tell you mostly in the shop is that you most backwash / reactivate the raisin with salt every month , in my case it was 10kg of salt in the filter , leave it a few hours and than backwash so the raisin is reactivated , you must think of the raisin as a flower , that collect all the calcium particles but at a moment will be saturated and in need of refreshment and cleaning ...so you must look the filter has an easy fill up cap for the salt ,if i would do it all over again i would adapt the home to the use of hard water , of course now we use city water and have sandy(sometimes) well water for the garden ...

Thanks for all input.

Probably easiest to go with the locally supplied product.
Barney/Kopkei, looks like I'm on the right track now.
I looked at the axact same ones as you pictured today Barney.

I am not going to do anything until next trip so I might as well wait until you install yours then come check it out.

In the meantime I will look at their manual on the web, in English, and see what it's all about.
Thanks
Mick

Your getting to be hard work.once again..tank to pump....pump to filter...filter to house ...sorry but my system feeds a 150,000 litre swimming pool.house and bungalow plus 2 apartments,soon.don't take my advice I'm only a hydroponic master and koi keeper in the uk where you pour a piñata of water out of the tap and even though it is drinkable looks like milk.as for people saying,oh it's looking like crystal clear water.go try have a pint and see if you've got it right.im getting bored now,I can't keep writing the instructions,I've got better things to do.oh before I forget,you can buy them fancy super stainless 5ft tubes that have a flush but then20 inch does the same.

Sorry Marco, didn't mean to get you all upset.
My problem is that the high calcium content is F^*individual up my pump.
So, I want to remove it before the pump.

That's what I'm getting at.
Mick

sorry marco , did you not post this?...I pump from the well to the holding tanks where I get most of the particles to settle and then pump to the house/pool through a 18 inch two stage filter.the big two part blue long units.
so are u using also 2 pumps?.. what i post here is own experience with the problem , i am surely not the expert but try to find a solution , and those blue filters did not do the job with me and needed so frequent cleaning /changing cartridges...too small at least in our case ...what are those filters? and do they remove calcium as asked by the OP ?...
to know if the water is potable you need to leave it test and than they will tell you what filters needed...
and reverse osmosis is not necessary , for good reverse osmosis you will need a bigger (expensive)system than the small idiot ones they sell here ..every situation is different ...
