Water Treatment 101


The descriptions and pictures below are designed to foster a basic understanding of the parts of your water treatment system.  When you call for service, we hope they will help you to identify those parts of your system that may need service.  When you receive an invoice from us, we hope the information below will help clarify which parts and systems we worked on during our service visit.



Water comes in from the well water pressure tank.







If there is high iron content then air is injected.







A small air compressor is used – usually plugged into a relay box nearby.





The water flows from the air release tank to the filter tank.  Air tank on the left and filter tank on the right.






Sometimes the tanks are insulated to reduce sweating in summertime.

Water in the filter tank flows through media.  When this media needs regeneration, the system “backwashes” and cleans the media.  Pictured is the control valve or filter head that controls the backwash settings.

When the filter head is rebuilt, we replace the spacers and seals.





We will also need to replace the piston assembly.

All of our media materials are natural and safe.

We check brine and backwash tubes for proper connections and leaks.  (photo –




This is a whole house water filter that removes sediment with a regular filter and can improve taste and odor with an activated carbon filter.  The blue housing unscrews from the white top.  Sometimes they get stuck and are very difficult to disassemble.






Our goal is to be Martha’s Vineyard’s premier plumbing and HVAC shop – we appreciate the opportunity to service, install, and “rescue” your water treatment system!
