I went over to SPOC tonight and waited for the sprinklers to come on so I could see if pavers alone will suffice. But of course since there were no telescopes present the sprinklers never came on. Will try again tomorrow. patrick On 30 Jun 2015, at 14:34, Wiggins Patrick <paw@digis.net> wrote:
Hi Chuck and Bruce,
Not sure about the pressure question. I put a paver on one of the heads and that seemed to work.
But if not we can go back to putting an inverted bucket over the heads and a paver on top of each bucket.
As for the switch (it is an electric switch, not a plumbing valve), the switch itself was labeled (up on, down off) but it was not obvious. More obvious markings have since been added.

This message from Dan Holmes didn't make it through the mailman software for some reason, but I feel it's important to the discussion, so I'm resending it myself.
It seems to me that if Dan could barely push it down with his entire body weight, a paving block won't do the job. Also wouldn't the pavers be a potential tripping hazard in the dark?
Also, is the valve/switch, whatever it is, clearly marked as to "off" and "on" positions? Is it accessible to anyone who might walk up to it? Where is it?

I've never operated the valve nor know of its location (guess I need to attend more star parties!), but just a thought:
Properly mark the valve positions on/off. <======= Important. To make the valve operation second nature, tie the valve adjustment (on/off) to a major action such as whomever opens the access gate must turn the valve to off. Whomever locks up the gate must turn the valve to on. Or, because of it's high priority (wet astronomy equipment is frowned upon) a task could be added to the Observatory opening and closing tasks which is a very well thought out deliberate list. Hoping to help! Clear skies all,Bruce Hugo
