Should we have water filter on the tank or in the kitchen

[ghworker2010]

We have moved into a rental building and that has an old water tank. It was mostly empty the other day (due to a problem) and had some dirty residue at the bottom. Maybe all tanks have this?

 

We are trying to decide if we should have a filter at the tank OR have one attached to the kitchen tank. We might later be having  business on the ground floor that utilizes the water. Thus unsure if we

should just have one on the tank?

 

What set up do you have?

 

thanks

Yes they do over quite a period

Filtration usually goes between the pump & entry point to house

The Filtration will depend on quality of water required 

I don't use anything it's for - Dish washing / toilets /shower / washing / ect

Do you plan to drink it ?

Hmmm. Mains water from the city? Can you smell chlorine? 

 

Many houses in the UK have/had open water tanks in the roof. All kinds of insects and stuff floating on top. People still drank the water, maybe still do.

For commercial purposes if food related, probably. You don't want people getting the runs from the water and thinking it is the food?

If the business is not food related. Back to answer #1.

Nah, open water tanks in the loft were header tanks for hot water systems such as immersion heaters, not part of the cold water drinking supply at the tap, that is mains-fed.

 

But you are right about dead mice, birds, etc in the tanks. That's why we were told not to drink water from the hot water tap.

 

OP, you should have some basic filtration between the pump and house, we use a carbon and resin filter set-up. We're on borehole well water which is pretty good (enough to drink) but kept the filter system in use when we changed from mains supply.

 

Search the site on TVF there are a few threads on water filtration.

PS It'll do no harm to clean the tank. When I remember, every couple of months, I chlorinate the tank to around 20ppm and flush this through to all sinks, showers, etc. I then let it stand for a few hours and then flush the whole system through with fresh water via tank and pump, by-passing the filters.

Yup agree. How clean you want your water? Is it groundwater, you will have sand on so on with it and you will find it in your tanks.

Filtering makes it clear, close to pump then or inlet of the water in your house. Filtering depends aswell on how big the particles are and maybe you need a set then starting first with bigger and in series filter for little particles.

You want to drink it, then you need an additional RO filter (not for sand, dirt filtering), combined with an UV-lamp. 

THe UV- lamp is instead of putting chlorine to it. It kills bacteria and others. As chlorine can give problems eventually in health , they found out and the UV- lamp came to replace the chlorine. In Holland (water company, city water) now they use those lamps instead of chlorine and we have high drinkable quality water.

The poisons and toxics you get in this water is unknown, but , what you put in your body is known.

Do it for drinking water

We do  the same .

I used two 100 cubic meter tanks to filter a mountain stream. They were filled, bottom to top, with river stones / river sand / charcoal / fine glass fiber layers to catch all sediment and most microorganisms ....

Both tanks fed into a stainless steel holding tank, and then fed into the house directly or via a passive solar heater. for hot water you could boil an egg with.  A simple gravity dependent ceramic filter was used in the kitchen for cooking and drinking.  Water quality exceeded WHO standards.

Wow, 2 x 100,000 litres those are some big tanks you got there.

Most setups have a tall sand and charcoal primary fikter treating water coming out of the tank.  This is fine for most purposes except drinking and cooking.  For that we have one of those multi filter moduke wall setups in the kitchen with three filter containers hanging off the bottom.  All up will cost around 25000 baht including both systems installed.  Some of the inividusl filter element modules will need annual replacement say 2000 baht and a back wash on the sand unit.  Everything else is two yearly.  Lots of places sell install and maintain annually.  

[The Theory]

Install a 3 stage filter (about 60 or 70 cm tall each) housings before tank. They need to be cleaned and washed, depends on you water usage. For drinking water need an osmosis water filter anywhere in kitchen or at any desirable place. 

But you need to drain and wash the tank before start using water.

We have a simple "crunchy bits" polyester filter on the incoming supply to the tank, takes out the big lumps that come along occasionally.

 

Three stage + RO for drinking cooking.

 

Our water is generally OK as we're not far from the treatment plant but the incoming filter still ends up the colour of stewed tea after a month or two.

Only place I have any filters is going to the washing machine.

All shower water heaters have small particle filters in them, as do most tap heads.

The city water feed is treated with chlorine to kill bacteria, all you need is a set of filters that takes out the sediment, most micro- organisms and chlorine.

You then have drinking water, Iv'e been drinking it for over 2 years like that, regular yearly health checkup's so far so good.. Or maybe i'll die tomorrow? Who knows?

Carbon filter on the tank, resin/UV/RO filter in the kitchen
