Custom ballast manifold question
I've noticed that once people ditch the stock ballast system/manifold for custom systems that they do not use a water strainer. Any concerns not having one and does having one restrict the water flow alot? I'm thinking of going the route of JesseC large diameter manifold with the large sprinkler valves.

The strainer is only there for the benefit of the valves. Once you pull those it's no longer needed.

Hmmmm. So if I go the route with those large sprinkler valves then I guess I should have a strainer.

Personally, I would make sure to have a strainer with any valves. If you think about it those valves were designed to be used in residential irrigation where they essentially run on tap water. Plants, sand, sediment, etc. all have the possibility to cause problems. There might be some valves that are intended for use with unfiltered water though? Not sure on that...

the design of jesse's highflow head being less restrictive is less apt to get strangled up by small debris. That being said a strainer on any water intake IS a good idea. The new intakes are perforated on the intake to prevent twigs and such from being sucked up and because the flow is bi directional should clear itself on ballast emptying. Jesse's intake is not cut off like the others have been and there for larger foreign material may get sucked up. But everything does have to make its way thru the intake pump before it ever reaches a strainer or valve on the older gIII.

The Irritrol 700 series valves I went with are advertised to not have issues with debris. I took one apart to check out it's workings and found that there was a small screen on the intlet that goes to the solenoid. Any debris that enters the main inlet of the valve will just pass through. With the valves I went with, the 3/4" are too small and the 1 1/2" require too much pressure. The 1" seems to be working for me, at leat on the sawhorses in the driveway. Two mor months or so before I can give it a try on the lake.
