Withers Posted August 30, 2004 Share Posted August 30, 2004 I'm fed up with my SQWD, so now I need to figure out how to replace it with PVC pipe. Has anyone done this? I just need to know what the best setup would be to give me the best flow. I realize that this is a simple task, but was just curious to see if anyone knew of a good way to get the maximum flow.

just dave Posted August 30, 2004 Share Posted August 30, 2004 What do you mean by maximum flow ?Do you mean more water flow as in volume or as in velocity? If it were me,I'd plumb it using PVC (no vinyl hose or barbs). I'd use the diameter pipe that the was used on the pump when it was rated. I'd would avoid using Ts and elbows,use sweeps and Ys instead. If you can't avoid using them use as few as possible. You can use two 45 degree fittings instead of a 90 degree fitting and you will not suffer as much loss or you can use a sweep (if you can find it in the size you are working with) or flexible PVC for even better results. The problem is the plumbing will not be as compact and tidy and you may not have the room for it. Link to comment
Withers Posted August 30, 2004 Author Share Posted August 30, 2004 thats just what i was looking for. i didn't want to use a T because i'd figure i'd lose a lot of flow from it, and it wouldn't be any better than the damn SQWD was. luckily i've got plenty of room, thanks for the response.

ReeferMo Posted August 30, 2004 Share Posted August 30, 2004 Jason, if you don't mind - what is the problem that you were having with the SQWD? If you posted about it before, I apologize for missing it. Link to comment
Withers Posted August 31, 2004 Author Share Posted August 31, 2004 i haven't posted about it before, but my main problem is that i have a mag 7, and once it gets pumped through my SQWD, i can barely notice any water movement. plus the way my tank is set up, i don't think that i'm gaining much from having alternating flow, so i've decided to ditch it.

onthefly Posted August 31, 2004 Share Posted August 31, 2004 Yeah they decrease the flow (depending on the pump head height) up to 50%. Why not go with a Mag 9 or 12.5 and sell the 7? Link to comment
Withers Posted August 31, 2004 Author Share Posted August 31, 2004 well i may eventually do that, but if this works just as well, then i can save a lot of money this way. Jason Link to comment
seis66 Posted August 31, 2004 Share Posted August 31, 2004 why do you want to replace your SCWD? Link to comment
RoOk_Reef Posted September 3, 2004 Share Posted September 3, 2004 Are you interested in selling your SCWD? Link to comment
Withers Posted September 3, 2004 Author Share Posted September 3, 2004 maybe, but i'm going to give the guys in my local reef club first dibs on it, i'm more interesting in trading it for frags than selling it. Link to comment
Withers Posted September 4, 2004 Author Share Posted September 4, 2004 i just realized that i misspelled SCWD 4 times in this thread, including the title, DOH. Link to comment
reefguyinpa Posted September 5, 2004 Share Posted September 5, 2004 Jason, Try a wye instead, Lot less friction but finding them in smaller sizes might be tricky. Good luck, Jim Link to comment
