Air hammer Arrestors

Why would they install one of this with a well system for domestic with 40# pressure?

Some people have to have the latest and greatest and they jump befor they look. I t also may have been for future considerations.

Thanks Terry, was curious, because this was the only set in the house and installed in the Master Bedroom Bath under the lavatory on the second floor or actually the third floor if you count the basement where the pressure tank is.
Just did not make any sense and was the first time I had seen this type.
House was built in 92 in Northern Maine. My Daughters new house.

Thanks for the reply. :slight_smile:

could be they had a water logging problem Marcel with the pump short cycling

Thanks Wayne, and here was the configuration in the basement, appears to be showing a storage take for well water, not sure, I just recommended that they hire a water purification contractor to evaluate the whole set up and provide instructions on how to maintain this whole thing.
I tested the pressure outside and showed 40#'s just like inside, but did not check the third floor. :):smiley:

After seeing your post (#5), I believe your post (#1) is a result of an experienced salesman. Can you say…“add-on sales”?

I wonder why 2 bladder tanks Marcel

Don’t know Wayne, that is what I am trying to figure out, I am not the best plumber, technical wise, here. That is for sure. Had me baffled at the installation when I was there.
I think, recommending a plumber might be prudent, and like Jeff said above, it might have been a good salesman. :p;)

I couldn’t figure out if that big tank is for storage or for treated storage water.

This was the third owner of the house and this was all there when he bought it.

Thanks for the help.

I think Jeff might be on the right track. Only a good qualified plumber would know I guess.

I am sure it is only for storage Marcel, it doesn’t appear to be in line with the softener only with the smaller bladder

That is the way I saw it to Wayne, but there is one valve that is shut and made me wonder why also.
I hate it when I am boggled like that due to my ignorance in plumbing of the sort.
Although, I will recommend a plumber to evaluate the installation and correct a couple of S-traps that I found, the house was great.
Well, it should be for $250,000 in Caribou, Maine. :mrgreen:

Damn, it’s to only place you can go in Maine where you can drive for 114 miles and the only thing you see on the GPS is Interstate 95. :mrgreen:

Sounds like a great place. Marcel good luck and let us know the outcome.

I only see one. Wayne.

The first tank on the left is a retention/storage tank to remove sediment and white drum next to it has a chemical injection pump to treat the water for some condition. (could be acidic water or other conditions making the water unpalatable or corrosive. The black tank is a salt drum for the water softener next to it.


Your advice to hire a water professional is appropriate because your daughter needs to know what condition is being treated and she needs to learn how to service the system to keep it working.

She may have to blow off the sediment periodically and she also needs to know what condition is being treated and how to service that portion and add chemical.

I agree Mike and thanks:)

I was wonder if the large one was a sand filter Micheal but they do make a bladder tank also.

The white chemical tank and injection pump is most likely a chlorinator… note the bottle of chlorox on top of it. There are a number of reasons to chlorinate beyond simple bacterial control. Most people I know in Northern NE (I am from Northern NH and Maine) have no interest in chlorinating because they believe in “City Water”. I had a chlorinator in my home in NH for years. It was there to eliminate one problem and help with another. The one it helped with was to reduce the iron content of the water. Chlorinating “helps” reduce iron. The problem it eliminated was a problem called " bacterial iron" which has nothing to do with having “ionic” iron in your water.
Bacterial iron is a bacteria that lives in the interface between water and air. It forms a black sludge that sometimes can be found in the toilet tank, if present. If the chlorinator has been working, however, you will not find it there or anywhere above the chlorinator as it will eliminate the bacteria.
Also, keep in mind that a water softener when used with the correct salts also can reduce iron content in the water. It may be that the two were installed to help reduce a high ionic “iron” content in the water which by the way is somewhat prevelant in Northern NE. I had bacterial iron problem and a slightly high ionic iron content. The chlorinator did the trick.

Thanka Larry, good info.
I’ll make sure my daugher gets someone to educated them in water conditioning and purification.
I know I could use more education on the subject. :slight_smile:
