water odor filtration
 
got my hot water running @ my new weekend place --
however, the well water has a lot of mineral / sulphur smell, and the hot water heater exacerbates the smell -- I have a very large filter in the tank house, but it apparently does not filter odor.

On the bathroom / shower side I think we can get used to this, but on the dishwasher / kitchen sink side I think this may be a problem.

Any suggestions?

I really don't want to go the route of an expensive water softener system.

Add a whole house charcoal filter. Do not hook it up to just a few lines, hook it up right where the main supply line is from the pump.

I have a "whole house filter" from Lowes and it is right after my tank (feeds the whole house) -- I'm hoping I can just get a better filter, although the one I've started with supposedly filters chlorine odor (of which there is no chlorine in my well -- it's a private well on a farm, so there's no municipal chlorination).

If it's not charcoal then that's not the one I'm talking about. It will be black inside.
100 % sure it's installed in the right direction? It will say in and out on top of the housing.
If it is charcoal and you know it does not need changing then better get a water test to see what causing this.

Centaur carbon is effective in removing relatively low levels of hydrogen sulfide (rotten egg odor) but for high levels of hydrogen sulfide some form of oxidation is typically required. Hydrogen peroxide or chlorine injection are two specific chemicals often used. If the oxygen reduction potential (ORP) of the water is sufficiently high a catalytic filter media such as Filox will be effective.

Most so called whole house cartridge filters are granulated carbon (GAC) but not Centaur carbon.

Well, I've been studying this issue, and it's very interesting what I've found is this:
1) Vacation or weekend homes are prone to the water odor issue
2) If cold water doesn't smell but hot does, it's most likely the electric water heater: this is quite possibly a bacterial issue
3) Changing the anode may not have any effect in a vacation home heater.
4) It appears that there is a very simple solution- adding 2 pints of Hydrogen Peroxide to a 40 gallon water heater, lettiing sit for 2 hrs, eliminates the odor for the duration of the visit (must be repeated each time you return).

Anyone can corroborate this?

And a re-read of Bob999's prior post shows that he was right on this- corroboration!

thats right just as bob999 said your on the right track....filtration is the key.also there are a good selection of filters from lowes as well to help in your case you may want to check them out...:yes:

I think somebody on here posted once about doing the same thing with bleach :thumbsup:

With a high sulfer odor a carbon filter helps but will not correct the situation you have. The smell is created by bacteria in the well.

Since you are on a well the bacteria causing this odor is in the well and the ONLY way to correct this is to shock the well. If you can remove the well cap and pour 1 gallon of bleach into the well. Open a hydrant and run the water until you smell the bleach. Let it set for 4-6hrs then run the water until the smell of bleach has gone or almost gone.

DO NOT SHOWER with the full strength bleach in the water.

Problem is the bacteria that is in the well reacts really well with hot water and the hot water only amplifies the odor.

You can throw filter after filter at this but it won't help until the well is shocked.

You may have to shock the well every once an a while to correct this problem. There are clorine pellet droppers you can install on the well but I would advise you not to do this. Because the pellets that drop sometimes do not fully dissolve and can build up and create a hard type rock. If this happens on the well pump sometimes it's a real pain to get the pump out to either replace or service.

If the well head is a metal head then you need to make a long funnel to pour the bleach down the well. The bleach can cause damage to the metal well head over years.

The well water level is @ 89' below the surface- my pump (3 1/2 h.p.) is @ 210' below the surface- this well is a very good one- could produce 70-80 GPM with a higher HP pump- would one gallon of bleach do the trick?

plummen 02-13-2012 11:06 PM

You have water at 89' but your pump is sitting at 200 plus feet?
What size of wires are you feeding that pump with?:laughing:

Plumber101 02-13-2012 11:07 PM

Yes one gallon will work.

When buying bleach look to sodium hypochlorite is at least 5%. Wal-mart cheap bleach is 6% and there are some that are lower. Just make sure it is at least 5%.

The trick is to let it set for at least 4-6 hrs.

When a well is drilled the fresh well is normally shocked for 24hr and with 3-5 gls of bleach.

You want it to attack the bacteria in the well and the aquafier.

We shock our well 2-3 times a year. Mainly in the summer.

Don' t remember but they are definitely sized correctly- had a professional well company install the pump.:thumbup:

With the water table at 89' and pump at 210' sounds a little odd. But the aquafier may not feed as fast as some and you need the extra depth to keep from running dry. But your good water may be at 200'

Do you know what aquafier you are in?

Probably a 10 but might be an 8. Not uncommon.

Being that deep you probably have a 5-8 stage pump. 10-13 amps
