Okay here are some facts below. You will lose head pressure with any downsize in piping. The ampmaster actually loses alot when you go to 1 inch versus 1 1/2 inch. I could not even imagine 4 1 inch pipes. You woould cut your flow to nothing. You will cut your flow by 60% if you go with one 1 inch pipe versus one 1 1/2 inch pipe let alone the 4. Every foot of vertical piping is a foot of head. Usually 4-5 feet high to top of tank. Every 90 degree bend is a foot of head. Every 10 feet horizontal pipe is a foot of head. Here is the chart below and facts.
[QOUTE] Dolphin Pumps newest addition to our Aqua Sea family of low rpm pumps. This pump has all the latest pump technology, including the most water flow per amp of any low rpm centrifugal pump worldwide. As a very satisfied new Dolphin Pump customer said: " It turns the competition into road kill ". We are so pleased with the quality of this pump that we gave it a nine year factory service guarantee.

The Amp Master has a 1/15 HP fully outdoor rated, maintenance free, highly efficient motor with a full load amp rating of 1.3 amps. The Amp Master 3000 incorporates our Aqua Sea Euro molded wet end which features a one piece balanced Noryl impeller with our time tested carbon/ceramic marine seal. This wet end is manufactured to very exacting tolerances. The Amp Master 3000 has lower vibration and noise levels than any other centrifugal water pump. Used with our new pump pad, this pump is so quiet it can barely be heard.

This pump operates at .8 - 1.1 Amps, has a cut off pressure of 17.5 head feet, and has a max flow of 60 GPM through 1.5" PVC pipe. This pump can even operate with one inch plumbing where the max flow is 26 GPM. Another benefit is that the Amp Master has virtually no heat transfer.

sound like it best to keep the 1.5 inch pipe
thanks for the info

Oh They do make attachments to cut it down to like 6 1/2 inch lines as your can see on their page. Just dont expect it to be the ampmaster 3000 anymore /ubbthreads/images/icons/smile.gif Since it is a non pressure running pump its GPH go down quite quick with pressure.

OK All the things your saying are on the web site. But they all refer to 1.5 to a 1'' line. Nothing there talks about spliting it into more than one line. What is the difference between one 1.5" line and two 1" lines, why would there be more head pressure on what now is a 2" flow over a 1.5" flow? If what your saying is true and I'm not saying it isn't then the Dolphin 6 (1/2") adapter is total useless. ie 1.5" to 1" cuts flow by 40% then 2x1" would cut flow by 70%? This would say flow thru 6 x 1/2 would be like -500 % flow. So I think, and it's just my thoughts that the head pressure the Dolphin web site is talking about is because your cutting down the flow path by 1/3 when you go from 1.5 to 1. I can understand this, but think there would be less problems with 2 x 1" line.
Please set me stright I also like this pump alot and am thinking for running one on you 150 reef tank to move water out of the sump to the tank. I was also going to "T" the line into two 1" lines don't have room to run 2 1.5" lines.BUT if I'm going to lose 70% of the flow the pump will not work. Think I'll see if I can get something from Dolphin on this...........
