Help! Wacky Gravity Ballast Issues

[MJHSupra]

The gravity 3 systems worked slow on the modern day bigger ballast bags and had issues over time with the sprinkler valves or pumps going bad.

The system had 1 big pump to feed 3 bags that was directed thru a manifold with sprinkler valves. Each bag had a drain pump to empty. Four pumps total. The system had a set of fuses under the dash (low amp draw) and had switches in the dash.

I would check all your electric connections for all pumps with a multi-meter. Check your switches to make sure they are good.

You have options:
1) Find the bad valve, bad pump, or electric issue and replace it.
2) Replace the system with a motorized ball valves. There are some post on this forum about it. You can buy supplies on eBay.
3) Replace the system with three modern reversible pumps from a company like Wakemakers - Jabsco Pumps or Johnson Pumps, etc.

Those are cheapest to most costly options. You get what you pay for on those options.
