Hi guys and gals! Want my .02? Well, I'll give it to ya anyway... :lol:

In my opinion it's possible to hash this subject indefinitely and still never come up with the absolute perfect solution. If I were in your situation, Ben, I would do the following....

Prioritize your concerns such as-

1. Not destroying your equipment with on/off cycling
2. Avoiding re-work that requires drilling
3. Creating "very good" if not "perfect" water conditions with flow.

You can even get fancy with it and place a weighted value on each issue you come up with. Add up the total value for each of your design options (OM, MBV, OM + MBV...) and make a decision, knowing it may not be perfect, but it will be very good. And if you plan it right you can switch things up a bit later based on how it goes. I seem to get that the MBV is the best bet if the aspect of #1 is a main priority.

:)

Wow -spoken like a true project manager - thanks Jan. Are you for hire? :D

Beleive it or not, #2 maybe a sligtly larger priority for me than #1. Although #1 is very, very close. Ok.. I'm going over to Duane's house in an hour or so to talk shop and then when I get back, I'm going to think about this weighting of priorities methods. you're right, it seems like all of the designs have their plusses and minuses.
 
Yep, all the designs have their less-than-ideal aspects to them so for the one you select, identify the risks and then identify your risk mitigation strategy. That's all you can do! :)
 
Actuators for on/off service have motors
that typically are rated for a duty cycle of

25% or less. Actuators used for modulating

valves must have motors that are
rated at 75 to 100%. Modulating valves
are often required to cycle frequently
which increases the heat generation of
the motor and increases the temperature
within the housing. Extended duty motors
are used which allows extended periods
of operation without overheating.


still not the answer I was looking for but it does help, I wanted a reference number to determine what the % was referenced to.
In short, I would not cycle the actuator too frequently

thanks Scooty.

what's too frequently though ya know? is it 8 times a minute like the makers of Reeflo said was too frequent... or are we talking every 5 minutes is too frequently? 10 min? etc. think we can find out from them what too frequently might mean when there is 79 degree water running through it?
 
Well - went over and talked w/ Duane and picked up some frags tonight (thanks again Duane!) and I think we have a winner!


The design:
Tee the main pipe right after the hammerhead driving water to both the MBV and OM units seperately. The MBV will feed a rotational clockwise stir at the bottom. The OM will feed 8 ports at the top of the tank pointed towards the center which will go off at 15 second intervals.

Here's an attempt to capture the under the tank shot of the main components - I apologize for the sloppyness, but ther was no clear way to draw it.

And here is what the ports in the tank would look like:

I think I'm going to call it good w/ this design.
 
Yep, I like separating the two & utilizing them to the fullest potential I don't like hanging over the top, why not just separate each orange on the OM on the back & eliminate the over the top from the front, with all the pressure you will hit the front easy. Otherwise / regardless I think your getting closer to a better design!;)

Congrats!

Thanks Scooty! I see what your saying and aesthetically I totally agree w/ you, however, It is pretty crammed in that overflow box already w/ 2 durso's, 2 cl drains, and 4 3/4" ports already - not sure I'd have any more room. And, since we can snug the pipes up against the backside of the wall anyway, it really won't look too too bad. Oh, and I think we can get some better targeted flow hitting it from the front side too. So... i think we're good.

Let's stick a fork in this baby and call her good- yeah? :oops:
 
Get that tank in & show us your plumbing as it progresses:D we want to see your dream come true! :)

will do.. i need to re-order up some new plumbing parts to make this happen, so will be working on that. I also need to lay out clearly where i want the holes cut for Jason at CFI so he can precision cut the holes- He should be working on the tank this week- yipee! :)

Scott (Szidls) should be coming over to take some measurements for the HVAC later today/this evening.

Elliot (Snowboarda) and I are going to get together and weld up that lighting rack in a few weeks after the HVAC is installed and the tank arrives.

it's all starting to come together.. but boy.. it's growing increasingly expensive. :eek:
 
Will do gabs..

oh.. and more good news - the BM250 is in route from Germany and should be here in a couple weeks too! happy dance time :razz:
 
Even more progress today...

Ordered up all of my plumbing - all is in stock so should see it in about a week. double yipee!!!

I also picked up 2 10ft steel box rails, 4 rollers, and some mounts for the lighting rack. I decided to scrap the idea of the Costco light rack for now b/c It doesn't look like I'll have much room to raise and lower it afterall.

Here's a couple fun pix...

10 ft box rails:

4 rollers (1 box shown on the right) & 4 mounts for the box rail (on the left).

and lastly...
I'm planning on mounting these right under the big HVAC return duct and on a big old 12" joist. in about the middle of the garage. the pink lines indicate where I think the rails will run.

Real nice double rollers. Do they have quick release brackets from the wheels to the mounting plates? I picked up a set of those years back for a double pocket door and felt that they were far superior than most (single roller tracks) that you will find.

no quick release, but you can unsrew a couple nuts to make it happen.
 
Maybe another ball union so you can run only one of either the O.M. or the M.B.V.
should you need to work on one of them for maintenance :)

P.S. while trying to improve mine the sand got stirred too much and I belive was the sole cause for the rtn of 2 of my favorite colonies 1 I fragged and should grow back the other tabeling acro went too fast while I was at work :-(
