rip that Sh1t out and put in a GD manifold
Can't do that - think of the Indexing-Valve industry
The valve is called a Richdel 205TF solenoid valve. It has a hex head plastic screw on the rhs, the central has a thumb wheel and forward has the solenoid.
If i unscrew the solenoid slightly then unscrew the hex head screw at the back water flows through. If i screw either the solenoid or hex head screw back in water stops
The solenoid and controller are both 24volt matched. You can hear/feel the solenoid click.
The local supplier here in Melbourne said if the Diaphragm was bad then i would have a constant flow of water. However thats not really the case in that i can only get water to flow through if i first loosen off the solenoid and then second loosen the hex head screw. I can then hear water flowing through
It will happen both ways. The 205 has a diaphragm with some hard plastic pieces in the center. There is also a screw that holds the hard plastic pieces to the rubber diaphragm. In the older ones the plastic nut and screw would break apart, and the diaphragm WOULD NOT OPEN. We see this happen a lot.
The local supplier is a piker and a hack
Yup, if that was his only advice given.
If i turn the thumb wheel screw clockwise all the way down is that the off position or on position.
Where should it be in order to activate the solenoid
Then the hex head screw at the back what does that do.
Sorry to be a pain just trying to sort a prob out for a longtime customer/neighbor
Stop asking questions and buy a new diaphragm for that valve. Or just buy a complete replacement valve, and replace everything at one time.
Just learnt that the thumb wheel as i call it is the flow control
