[TheForge] OT: Spring tile question

[Jay Hayes]

Andy,

I'm a little south of Weston, right off I-79 at exit 91, by Stonewall 
Jackson Lake State Park.

Washed gravel is gravel that has been washed at the quarry to remove any 
dust and dirt left from the rock crushing and screening operations. 
Unwashed gravel has a lot of fines mixed in that will make a mud when it 
gets wet that sets up almost like concrete. This can plug the holes in 
the perforated pipe that collects the spring water.

The gravel supplier will know what you are talking about. when you ask 
for washed gravel.  Here in north central WV all the gravel is limestone 
and comes from either Greer or Alcon, which are both an hour away in 
Elkins. It costs more for the trucking than it does for the stone. Where 
you are, you may have more options available.

I use chlorine too. I always dose a new system then again any time it is 
worked on, like cleaning out sediment  or changing the suction screen on 
a pump...
