When I installed my drip-line hoses (Rain Drip Drip-A-Long 1/2" hoses
with emitters every 18") I buried them about an inch in the soil. I'm
having some trouble with them now, and on Rain Drip's website they say
to keep the emitters out of the dirt. What do folks in this newsgroup
do? Do you bury the hoses in the dirt, only cover them with mulch, or
what?

Drip tape and 1/4 inch drip line with inline emitters are run at 10-15
psi and the output will be restricted if it surrounded by waterpacked
soil - more of a problem with clay soil, less with sandy soil.
Dripworks' (www.dripworksusa.com) 1/2 inch drip lines with extruded
inline emitters are run from 25 psi up to line pressure and can be
buried but work better on the soil surface. Any drip system lasts
longer when it is protected (covered) from the sun with organic mulch
that does not block emitter output. -Olin
