In-Stem Flow Regulated Popups & Their Value

' The most significant change to sprinkler system in 50 years  claims Valvette Systems owner and inventor Ted Serkin. (www.valvettesystems.com )
By using Ted's ISFR ( IN-Stem Flow Regulated ) sprinklers in our projects we are able to reduce and in most cases eliminate water over spraying on fences, buildings, sidewalks, and street medians plus, reduce water use on our landscape by 30%
We are also able to stock and use only 15 foot spray nozzles which we can bring down to almost two feet  sprinkler throw radius with perfect water distribution uniformity.
It is simple and easy to flush out the dirt and debris during our 'nozzle up ' of our project's which was one of the main reasons why Ted invented the ISFR popup. " I just hated getting drenched by all the popup spray heads I installed that had the generic manufacturer supplied flush caps on top of all those popups.' 
When the irrigation zone is activated all our ISFR'S popup sprinkler heads rise to the up position and can be individually flushed out individually thus reducing water wastage and we are able also to not get drenched.
The stems and popups have been trail tested by an independent irrigation efficiency testing lab Frersno, California so they ate proven efficient and with water saving and drought conditions worldwide, it is wise to look into trying out and retro-fitting your irrigation popup sprinklers and sprinkler nozzle stems with the amazing Valvette Systems 'Little Tuffy' line of In-Stem Flow Regulated components.
BTW, Ted also has a full line of shrub head adaptors that work with the same principle as his popups so you can achieve the same watering efficiency and water savings in your shrub bed areas too !
