1987 Supra Saltare

Ballast dude you gotta have good weight for boarding and surfing! I have two more Simer pumps on the way now!! Z5 looks awesome though, or the Monster Cargo.

Hah! I totally misspoke... I'd go with the monster cargo since I can't afford the Z5.

For ballast... I've got a good setup right now, but I think I'm going to start working on plumbing something in. What did you pay for your simmers? Fleet Farm here has them for $52 for the kit... they had 3 left in stock.... I should have bought them!

perfect, I'll pickup some indoor/outdoor silicone today, Jim sent me replacement RR so fortunatley I'm only dealing with 120 subrail screw's, none for the insert....That stuff's fragile...I've got it hanging in the shed and man you gottta watch the scuff's and ding's!!
I'll replace the silicone under the subrail and dab each screw hole?? Any tricks on the corner's ??? Heat gun???

I paid $75 a simer so thats a great deal. One pump can do a couple sacs easy but it's tough to get the one in the rear ski locker to be linked with any other sac. It's higher in the air and gravity will drain it into a lower sac. I'm putting that one on it's own pump.

Yep... heat gun... just be sure that you don't "stretch" it too far in one direction.... I tried to get it a little too tight and ended up stretching it and it wouldn't hold the insert right. youtube taco rubrail install.... it's a 3-part series that shows you everything you need to know!

Mikey -- What if you put a check valve between the two so it could only flow bench -> sack and then on the drain side sucked it out the top of the locker sac. I think a simer will pull enough water to counteract gravity.... right? Need a couple more check valves but.... quick and dirty pic, below. This could work for me, too. I plan on only filling the two rear sacs together.... this could simplify my life! Thoughts?

With the pic above, the entire ski locker sac will drain into the bench sac on the floor.

It's not the Simer that is the problem. When you turn the pump off, the bottom sac will become way too full and the top sac will not stay full without its own valve.

I have been posting on WW and searching a lot and the only solution I could find is an anti-syphon valve that is supossed to break up the syphon effect. You put it at the highest point in your line run and when it started to have a low pressure leak it introduces air to break it up. It was about $30 from Bakesonline.com. I am not sure if I will even use it now that I am getting three pumps.

Also there's no way you can drain from the top of the sac. All reversable pump systems sjhould have single fill/drian line at bottom of the sac or it will never drain all the way.

Looking at your pic above again.. people say if the fill/drain line for the top sac is run to a loop that is higher than the highest point on the top sac, it will not drain down. However, it will still syphon down EVERY TIME after you turn the pump off unless you route in that anti-syphon valve.

Also note that if you are running more than one sac on a pump, make the TEE as close to the pump as possible. Also make the lengths of hose the same length even if one sac doesn't need it. This will help the sacs to fill at the same RATE so they are full at the same time.

Another solution that you will NEED for our system is flow rate control on each sac. I have a manual valve on each sac. Once I add more pumps I will not need to open or close any sac - however, if I close a small sac 20% it should finish filling at the same time as a larger sac.

I am going out this afternoon and I will be doing some testing. Testing what heights to make my overflows. Testing what happens when I link different sacs together.

Makes sense. I'm just going to go with 3 pumps to keep it easy and try to avoid any kind of surprises. I'll never run the bags less than all-the-way full and plan on having the pumps on indivual switches so if they get done at different times, I don't really care. I will keep the lines/t's the way you recommend though.... that makes sense.

Where did you find check valves? There has to be a cheaper solution than the ones posted at WW for almost $20/each. My brother runs a landscape/sprinkler company.... I'm going to check with him.

What ever you do dont buy back flow/check valves from Hore depot. They dont work for chit. I had to put my valves back on while at the river cuz water was leaking out my bags. Was'nt fun.

[87SunSportMikeyD]

hematoma what specific ones at depot? They need to be swing check valves. I have the brass ones right now. Haven't used them yet but they do seal well. $4/ea. My local wake dealer had plastic ones for $20/ea. Ouch.
