Tsunami 800 pump upgrade project

[Fman]

Fman - thanks for the great write-up, I've got my account setup with wakemakers and am filling the cart for the order.

A couple things got me thinking, both regarding venting the bags

1. I wonder if all three bags could be tied in to one check valve/vent line. It seems like it could work since it's just air getting pushed out, although, what would keep the bags from venting in to one another. And for that matter, if a bag over fills and tries to push water out the vent line it may just end up filling another bag. Suppose I just talked my way right through that thought..... thanks for listening

2. If the bag is being vented, is there still a need for the anti-siphon loop on the fill side? The anti-siphon valve is basically there to create an air gap in the system so water won't be pushed/pulled in to a closed system. So, in essence, couldn't the "air gap" be located anywhere on the system? ie: bag vent located above draft line? Although, the anti-siphon loop helps prevent back-draining of the bag.

Certainly not trying to reinvent the wheel here, just some random thoughts I had.

Here's what I've got in my cart,

Attwood Tsunami 800 GPH Ballast Pump (x3)
Fly High Tsunami 800 / 3/4" Hose Barb Adapater W745 (x3)
3/4" Vented Loop Anti-siphon Valve (x3)
3/4" Non-Return Check Valve Fitting (x3)
3/4" Hose Barb Tee Fitting (x3)
Fly High 3/4" Straight Flow-Rite Quick Release Connector W740 (x3)
Fly High 3/4" Flow-Rite Quick Release Connect W736 (x3)

Last summer we found ballast hose at ACE Hardware, and everything else for the manifold can be sourced at Home Depot? Thanks again

Scott,

Sounds like you are off to a great start, and I chose to run the anti-siphon on each bag so water would not drain back into the bag. You dont need an anti-syphon on the fill side, this what the vented loops will do to eliminate water from coming into your system while driving the boat. I like having a seperate vent on each bag because when they fill it will start to pour out the thru holes in the side of the boat to let you know they are full.

Just make sure and mount the 800's as close to the bottom of the boat as possible, the lower the better for no hassle priming. If there are any other questions you have let me know, I can always give you my cell # to talk voice if need be. Its a pretty straight forward system, I have been very happy with it and it has been very reliable. Soooooo much better than the sprinkler valves!!! I think you will be very pleased, I can fill 1900 lbs of ballast in about 8-9 minutes.... which is acceptable to me. This is roughly about 30 GPM total with all three pumps running.

The only item I did not put back in my system was a water strainer, I have never had any problems with debris, but this is also another item that could be added. If you are in mucky, dirty water a lot it might not be a bad idea.
