Good Morning! We bought our house in October 2010. It was built in 2000. We have a 2 well with a Goulds jet pump. The well is 113, according to state records. All plumbing is PVC. The pump is in a well house in the front yard, and the incoming line for the house, as well as the outside faucets, run underground from the well house to the house (maybe 100 or so), and the outside faucet lines branch off somewhere underground between the house and well house. There is also water going to the shop out back. When we moved in, there was some sort of water filter connected to the side of the house. It consisted of two cylinders that were about the same size as those of the reverse osmosis system that is in the kitchen. However, the housing was broken in several places, as were the pipes. There were no filters inside. There was a bypass valve, which also leaked. I removed the filter assembly and plumbed the water straight into the house. The pump sends water to a galvanized tank (no bladder). From there it goes through a water softener, then out of the well house. The water softener looks pretty old. I contacted the company that drilled the well, and they believe it is the original unit. They said that many of the homes in the area do not use water softeners, as there is no real benefit. I bypassed the softener for a short time to check the water quality. The only difference we noticed is that sand started to accumulate in the faucets and the washer inlet. The water tasted and felt the same. Both with and without the softener, there is some green buildup in the dogs water container after a while that needs to be cleaned, and the bathroom sink gets some sort of orange and purple stains (or growth) after a while. The water, however, tastes really good. However, Im the only one that will drink water straight from the tap. My wife only drinks from the reverse osmosis in the kitchen. My first question: I am going to be installing a whole house filter in the next couple of weeks. I am looking at the Whirlpool WHELJ1 system. Does anyone have any experience with this system? Are there any other systems I should look into? I have not had to deal with wells and filters before, so Im relying mostly on what I can find on the internet. We have had a couple of companies out to give us quotes on installing various systems, but we just cant spend the thousands of dollars thay all want. Second Question: Where is the best location to install the whole house filter? It seems to me that it should be before the storage tank, to prevent any buildup in there. However, I have seen some after the tank. I also thought about putting it at the house so that I am not filtering the water going to the outside faucets. However, unless it is going to sit outside, I will need to install it in the attic where the main line comes in. Our attic is very large and I can almost stand up straight, so that wouldnt be a major issue if that is the best place. Any insight or suggestions would be appreciated.
