Rastinger62 Posted November 17, 2013 Report Share Posted November 17, 2013 Need some help!!!!! The system: 4x 8x2x2, 1x 6x2x2 with a 6x2x2 sump Currently using 2x 10,000lt per hour Jebao (170w for both pumps) Apart from the 2 pumps pushing into each other at the "T" pvc piping piece, if 1 pump was to fail the other pump basically just flows back into the sump and doesn't continue up the return piping. I currently have tried a 17,000lt per hour which goes straight into the return great but the flow isn't there like the 2x 10,000lt pumps To add a new sump pump of 23,000 - 28,000 I'm looking at 500w which is a lot higher then expected. My question: Is there a way I can use the 2x 10,000lt pumps and use a better pvc piping method so it doesn't restrict the flow if one pump fails or is there a low watt larger pump I could buy for a reasonable price or Is there a better way I could plumb the system to help the 17,000 do a better job. I'm just confused on what to do. Cheers Link to comment Share on other sites More sharing options...
beencees Posted November 17, 2013 Report Share Posted November 17, 2013 I'm sure there is a reason why not but can you just use a "Y" piece instead of the "T" piece? Link to comment Share on other sites More sharing options...
Rastinger62 Posted November 17, 2013 Author Report Share Posted November 17, 2013 I've never seen a Y piece for sale in the pumping section before otherwise I would of. Link to comment Share on other sites More sharing options...
Rob3am Posted November 17, 2013 Report Share Posted November 17, 2013 can you get a 1 way flow valve Link to comment Share on other sites More sharing options...
Donny@ageofaquariums Posted November 17, 2013 Report Share Posted November 17, 2013 They are expensive, but yea 1 one valves do the job. or.............. Aquael PFN25000 PLUS 350 watts at maximum 25,000 lph Dc pump, so as you turn down flow it uses less power. 7.5 metre head height, so aint gonna have any drama with those racks. You pay a bit more for them but the 2 year warranty covers the impellor and the build construction is very good indeed. Link to comment Share on other sites More sharing options...
Sneakypead Posted November 18, 2013 Report Share Posted November 18, 2013 Mate grab a inline dual check for each pump, tradelink or Reece stock them, look into them and see what you think. I may be able to help you out with a cheaper price. Link to comment Share on other sites More sharing options...
Rastinger62 Posted November 18, 2013 Author Report Share Posted November 18, 2013 thanks guys. I've played around with my plumbing and can buy a 19,000lt pump for $200 sent to me with 200 watts of power so I will go with that. I like the info on that pump donny but just out of my price range for now. Link to comment Share on other sites More sharing options...
JayPee Posted November 18, 2013 Report Share Posted November 18, 2013 What size is the PVC pipe that flows to your tanks. 17000 should do it. I had 17500 running my old system no problems. If you've used 25 mm from the pump you may have problems getting more flow. Just a thought. Link to comment Share on other sites More sharing options...
aquaholic99 Posted November 18, 2013 Report Share Posted November 18, 2013 Why dont you use one pump to supply top row and the other pump to supply bottom row? Also, having a loop on pipes will provide better flow than a blindend. I would only use a check valve as last resort as they are inefficient and do fail.
