Water Softeners Centennial Colorado

Last night we made a late evening service call for a couple on a water softener in Centennial Colorado. They have a 17 year old softener that is making their water salty. This is a common complaint on older units. The unit and surrounding plumbing has several leaks. These older units have rubber seals & O-rings. As they age, the rubber starts to crack. Over time, the rubber deteriorates and the hard plastic & metalic pistons can score or scratch the valve body, the piston, and the rings. This will cause widespread damage to the overall valve indicating replacement of the control valve or maybe even the entire unit. In this case, the resin has been in service for 17 years without the benefit of chlorine reduction. It makes better sense to replace the whole unit.
