Inlet Valve Removal - G800 Series - Hunter G835 Owner's Manual

inleT VAlVe ReMoVAl – g800 SeRieS
With the main-line or sub-main depressurized, the riser assembly removed, the water extracted from the body cavity
and the safety interlock feature disengaged, proceed with removal of the g800's white lower snap-ring and inlet valve
as follows:
First, notice that close to each end of the white lower snap-ring there are two raised areas (fig 76). these two raised
areas are used to remove the white lower snap-ring. also notice that the inlet valve has two posts protruding upward
on top of the inlet valve. take a moment to note the orientation of these posts and how they nest within the white
lower snap-ring. understanding this alignment and orientation will help later to confirm that the white lower snap-ring
has been properly seated after installation.
to remove the white lower snap-ring, use the 16" needle-nose pliers tool to grab the outer side of the two raised
areas near the ends of the white lower snap-ring. next, squeeze the two raised areas together with the tips of the 16"
needle-nose pliers tool (fig 78). this action will collapse the white lower snap-ring. While holding the collapsed white
lower snap-ring, pull the 16"needle-nose pliers up and out along with the white lower snap-ring (fig 79).
Inlet valve removal option 1 – once the white lower snap-ring has been removed, the inlet valve is released and is
ready for removal. g800 series inlet valves are removed from the body using the g800 Valve tool. prior to using the
tool, familiarize yourself with the individual features of the g800 Valve tool. First, notice there are two metal hooks at
the bottom of the tool (fig 80). these hooks are used to grab/hook the inlet valve for removal from the rotor's body.
the black plastic part of the g800 Valve tool includes physical features that hold or nest the inlet valve to the tool
during inlet valve removal and installation.
In order to engage the inlet valve with the g800 Valve tool properly, you must be familiar with the pointing and
alignment features on the tool's black plastic part. First, look at the three retaining screws on top of the tool. next,
find the screw that has a pointer arrow engraved around the head of the screw (fig 81). this pointer is used to indicate
the direction and alignment that the tool must have as it is inserted into the rotor's body. a second pointer arrow is
located directly below on the underside of the g800 Valve tool (fig 82).
to remove the inlet valve, it is necessary to align the pointer arrow on the g800 Valve tool with the alignment dot
on the rotor's flange. The alignment dot is centered on the flange compartment lid adjacent to (next to) the body
cavity opening (fig 81). A second alignment dot is located below the lid in case the flange compartment lid has been
removed. align the pointer arrow on the tool with the alignment dot and lower the tool into the rotor's body.
as the g800 Valve tool is lowered into the rotor's body, recessed areas on the black plastic part on the tool will
engage vertical rails inside the body wall (fig 83). the tool must engage these rails or the tool will not align with
the inlet valve below. continue pressing downward compressing the spring on the g800 Valve tool. While holding
the tool down with the spring compressed, turn the tool's handle clockwise until it stops. next, release the spring's
compression by lifting the handle slightly on the g800 Valve tool. this action hooks and locks the inlet valve to the
tool. Finally, pull upward on the tool's handle to remove the tool and inlet valve from the rotor's body (fig 84).
