Water Issue?

[timvasqz]

like a sprinkler electric valve the sporlan valve 94pt has an
electric magnet that pulls a pin valve to let water out from behind
the plunger which at rest traps water where that water pushes the
plunger to a seat and blocks the main water flow. therefor to block
a flow there must be pressure. since the pressure is off during
storage the valve float open and only reblocks once water pressure
gets back behind the plunger. while atrest with no pressure the seat
scums up and is hard to reseal, also the pinhole is hard to reseal
so water escapes from behind the plunger and it wont close. Full
timers have little issue with this because their system is
constantly pressurized like a home irrigation system.

Best bet is to turn the electric pump on for 15 min (or less not to
burn up the pump)and see if the valve seats by its self as it cycles
water thru or just open the valve up and clean it off.

I have seated it by using high pressure on the fill hose in short
burst but if there is an internal pressRed that will have no value
plus it could cause other issues.

I have had to open the valve up more than 5 times in 5 years. it is
usualy patina on the brass and rubber that hangs stuff up

Mine is under the bed.. The pump while in that position is probably
just pumping water in a circle.
