[QUOTE="roys, post: 426039, member: 5044"] Level control is done by the ball cock on the header tank closing, causing the pressure to rise and shut off. Dry run protection ( and burst main discharge pipe) is not mentioned in the manual from what I remembered but I added it myself by adding a timer that shuts the system down if it ever runs for more than 90 seconds, this works because if everything is healthy the pump will never run for 90 secs even with the ball cock full open. It would stop for about a minute and then start again, the fact the motor stops resets my timer. The booster pump is just supplied with a 13 amp plug so only basic motor protection. [/QUOTE]
