No more sprinkler valves

[Fman]

Hello,

I am a Supra owner (08 22V sunsport w/gravity III), usually over on the Supra forum. Wanted to pop in here and see if anyone has done the upgrade ballast fill system on there Moomba? I am in the middle of removing the sprinkler valves and replacing them with Tsunami 800's, so I will have a seperate pump for each bag. I have already removed the intake grate, grinded down the scupper, and re-installed. My parts to complete the project will be here tomorrow and I hope to have it finished by tomorrow night. I am installing the vented loops for each bag to prevent any filling of the bags when not filling with the pumps. Wiring is already there because of the sprinkler valves.

Just wanted to find out if anyone has done this yet and if they had any tips. I will post pictures when I am done, the new system will fill my 2000 lb system in about 5.5 minutes, compared to about 13-14 minutes with the single pump.

Thanks,
Travis

Travis sounds cool and welcome to the Moomba forum also.

Razzman is doing a set up with the Vented Loops as well. Several of us are kinda waiting to see how it works out before the big plunge, so to speak. Ill be looking forward to the results as this winter i want to redo the ballast system on my LSV as well.

several posts on this topic around here, especially this spring.
browse around or search and you will find a ton.
razz has been looking into some interesting ideas...
good luck and welcome. I think you will find this to be a much more informational board than the supra forums for wakeboats. I know I have

Jason at wakemakers is helping me with this conversion. They have done a few boats themselves with good results with the tsunami's. I will search around to find out if anyone has any pictures. Having a 12-14 minute fill time on my system was getting a little rediculuos, I can live with 5-6 minutes. Plus those sprinkler valves fail quite a bit probably because of the heat in the engine/trans compartment.

I can see why in '09 they went to impeller driven systems, much more effecient and can take a little more abuse. They are using the JABSCO reversible pumps. I almost went this route but the 800 Tsunamis put out a little more GPM's (9-JABSCO, 13.5-Tsunami 800) and it was about $500 less expensive.

Anyway, thanks for any feedback anyone has.

Jason has been helping me out as well. I am waiting to get some more stuff from him. I did do all the changes. I have spent lots of money, and it still is not working right. I have one more shot before I try something else.

My system consist of:
3 Vented Loops
3 Tsunami 1200gph Pumps
3 1" Scuppers (which are going to be changed out with Thru Hull Fittings)
3 Ball Valves

I have one pumps ofr each bags. The bags fill alot faster than with the valves in them. The problem that I am having is the bags fill while boat is in motion. That is why I am removing the scuppers and replacing them with the thru hull fittings. I did keep the drain pumps the same. I am not to concern for the output as I am with the input of water.

I am doing the same exact setup except I am using the 800's, my parts will be here tomorrow and I am going to finish. I already removed the intake grate and grinded off the scupper and re-installed on the boat. I would bet when you remove the scupper it will stop water from coming into the system. With the scupper on when you drive the boat it is forcing water into the system and without the sprinkler valves the vented loops will not be able to hold back the pressure.

I will post up some pics when I am finished with the project.

Fman, one question and then i will wait for the pictures. Did you remove the original fill pump?

[Fman]

Original fill pump (RULE 2000) and plastic strainer will no longer be used in the system. As we all know, the RULE pump is not good for getting a prime. Leaving it in the system would be a problem. The plastic strainer just adds friction loss which decreases flow. Basically you have the grinded intake (no scupper on bottom), 90 degree elbow, ball valve, manifold with 3 tsunami's.... each Tsunami going into seperate vented loops, into the bags. I am not modifying the drain system, it seems to work well and has a seperate pump for each bag right now. Although it would be simple to install a larger pump to increase drain time, I might do this as a winter project.

Its a pretty simple system, sprinkler valve wiring will connect directly into the new tsunami's. I will post some pics of the entire install once I am finished. I am planning on finishing tomorrow, but I am leaving for a week long camping trip on Sunday, so I might not have time to put the pics up until following week.

I love my Supra, but this ballast fill system they put on this boat is weak sauce.... hopefully after the pics are up some more people who own '08s and older will tackle this project and improve there system. Especially if you have the larger 750's in the rear. Going from a 14 minute fill time to 5.5 minutes is going to be great. I am converting the entire system for under $300.

I am assuming the Moomba's are using the same sprinkler valve system???? guess I should of asked first.

I'll be interested to hear your results. I always assumed that when I went to dedicated fill pumps I'd have dedicated intakes (like the 09's) as well. If you can get good results with the single intake that would save a time, money, and holes in the hull.

You are correct with the sprinkler valves. sucky system for time but does work good otherwise.
