Here are some instructions for sanitizing your RODI:

Chago this may be a strange question, but why are these systems built with flow restrictors on the out let if the pressure is so Important? why not use a 60psi check valve on the wate lines and you could tee of to as many membranes as you want? My backround is in Industrial systems, and that is what we would do.
Mikey I'm not sure I understand what you mean. A 60PSI check valve? a check valve is a device that allows water to pass through freely in one direction and not allow any to come back in the opposite. If your using something that only allows water to pass at 60psi then that is exactly what a flow restrictor is. Some people rate them by gpd, when really a 150gpd flow restrictor is designed to only allow water through the drain line once a certain psi is reached. I may misunderstood you but I think what your calling a 60psi check valve is actually a flow restrictor. On drain lines you should have a flow restrictor and a check valve. Check valve prevents any back up and makes sure that the back pressure doesn't mess around with your flow restrictor.
I have installed many plug and play and have built many commercial units and all used flow restrictors of different sizes, plus a check valve to make sure no back pressure would build. Industrial units, I assume you mean the huge 100,000gpd systems etc, I honestly have no experience with and have no idea how they even work. Although again they would need some sort of flow restrictor so pressure can build up inside teh membrane, otherwise Reverse Osmosis would not be able to occur. You may have just mixed the words around between flow restrictor and check valve.

chago, i believe what Mikey is asking why not use a check valve with a 60 PSI crack rating, meaning it won't let fluid flow in one direction, and in the other direction it won't open until it has 60 PSI. I think you guys are talking about the same thing just using different terminology from different fields. I too use check valves at work on a daily basis, we don't call them flow restrictors. Flow restrictors for me, and i'm guessing Mikey as well, is something like a needle valve or throttle valve that will only let so many GPM pass at a certain setting. Mikey, please correct me if i am wrong in what you were thinking

ya I agree I think we are saying the same thing. I really have no experience with these types of check valves so can't answer on them.
I believe the city inspector was worried because he saw a domestic water line going into the RO unit and then continuing out to the mixing tanks. He didn't fully understand the system and was thinking that if the municipal water pressure failed, these lines could essentially drain the salt water mixing tanks back into the municipal system. This of course could not happen as the RO lines in the tanks are above the water...but just to be sure, he insisted upon back flow preventers (it is easier sometimes to just do it than to explain the whole system).
BTW, the inspector was there to do a final inspection on the entire basement reno we did and he wanted to look in the fish room to see the sink and drain there and then saw this massive threat to the entire global water system.
Thanks.
LOL no kiding, sometimes they just need to say something to make it seem like they know what they are talking about. Lake Ontario is only estimated like 7 trillion gallons and Peters tank is 1350 gallons of salt water. Ahhh I can just see it on CNN now, Lake Ontario now the Toronto Sea due to Oakville mans fish tank leak.

No, I thimk you have it backwards. Oakville man drains Lake Ontario to facilitate 20% water change. RESULT......his property tax goes up proportional to the depth of the lake.

good news is, there would be a lot of new lake front property

Everything is impressive (the tank, the build, and the story). So when is the book coming out? I'm certain that all the problems that you have had to solve would be helpful to many other reefers out there.
Are there any more updates on the fish room? Last pictures looked like there was still equipment missing.

Forgive me Peter, I've been playing catch up for the last week on the thread so I did look to see if this was addressed, but I apologize if it was and I missed it. This is definitely not the case with fish that are likely to jump. It has nothing to do with whether or not they are happy, fish like wrasses, basslets, pseudochromis, and anthias (among others) are some of the worst jumpers. They don't jump because they are unhappy and want to escape the tank, they just jump when something startles them either inside or outside the tank.
It's kind of like if you were watching the tank and someone snuck up behind you and poked you in the side. You'd get startled and jump a little. It doesn't mean you're unhappy, it's just instinct. Same thing with fish and when something startles them they can dart in any direction, including up and sometimes this means out of the water. The fish have no concept that they can dash up and out of the water and somehow not come back down. Obviously in the wild fish are usually facing unlimited space to dart in all directions including up and if they do leave the water their is nothing stopping them from falling back down like there might be on our tanks at home.
This leads many people to cover their tanks with things like eggcrate (not the best idea as it acts as a light diffuser). A better idea is to use very fine netting because this has less impact on the light and no impact on evaporation. You can also feed through it so no need to move it all the time. There are online vendors like Bulk Reef Supply that even sell the netting by the foot and with plastic frames so you can build your own covers that can then easily be moved for when you need access to the tank.
I will give you that it's not like a fish is destined to jump out, but it can, and very often does happen. Though the more room the fish has to dart around like there is in your tank, the less likely they'll end up outside the tank, it's still better to be safe than sorry.
Just wanted to throw in my .02. Hope you don't mind the perspective (though considering your posts, I doubt you will).

My personal motto is if the fish is shaped like a torpedo, that's exactly what it is capable of doing right out of your tank! :fish1:
