Remember after a very good cleaning you should chase the water out of the gun with mineral spirits or the ball barring in the gun packing will rust and get stuck.

@Alex Miner , I am investor and also wholesale.

For the kitchen faucet, the aerator might be clogged with minerals.

@David Miner, no I haven't.  

Your house is renting for just over .5% of its value per month, most of mine rent for between 1% to up to 3% of its value per month. 

Maybe you could potentially sell mineral rights to someone.

The house could burn to the ground the day after I buy it and the insurance covers twice what I paid for it and I would still own the land and mineral rights (which means something with the Barnett Shale formation and gas lease potential that exists even for the smallest parcels in Fort Worth).

Also, i'm not exactly how to figure this into the equation, but it we may be able to get the mineral rights for 7 acres (haynesville shale could be very big for this property).

In a tank type WH the minerals which precipitate out of the water tend to sink to the bottom of the tank where they can be drained off.  

Apologies if this should have been posted elsewhere but seemed to fit here....Out of the blue my wife has been approached by an energy firm looking to lease 2 lots that she owns For the express purpose of paying royalties on the mineral rights.
