Ellisz Posted July 11, 2021 Author Report Share Posted July 11, 2021 So a Waterway 1HP 9.5 Amp pump can be had for $250 shipped. A 3/4 HP pump can be had for $200. The Waterway 3/4 Pump (3410310-15) appears to be labeled as 3/4 & 1 hp. I think it is 10 amp. You think this wouldwork? https://lesliespool.com/308623.html I can tinker with the current one later.

RDspaguy Posted July 11, 2021 Report Share Posted July 11, 2021 That'll be fine. Quote Link to comment Share on other sites More sharing options...
RDspaguy Posted July 11, 2021 Report Share Posted July 11, 2021 Just to be sure it's not a plumbing issue, as you have been doing some plumbing work, try removing the pump and running it. See if it trips off under 0 load. If so, buy the pump. 1 Quote Link to comment Share on other sites More sharing options...
Ellisz Posted July 11, 2021 Author Report Share Posted July 11, 2021 Sure, thing. I redid the manifold using braided tubing to the existing 1/2" spa flex with short sections. I don't have any 90 elbows any more. The previous guy had some how modified the fitting with the hot stick and the temp probes so he did not have to replace it. Not sure how he did it but I removed it and replaced the fitting with the probes - just did not use the hot stick. Can't vouch for the rest of the plumbing. Going to see about capping the lines as I remove the pump to not have to drain and refill again Should be fun. Thanks Quote Link to comment Share on other sites More sharing options...
Ellisz Posted July 14, 2021 Author Report Share Posted July 14, 2021 So this thing is still confusing me. I drained the tub and pulled the pump. Plugged it in and it ran fine and the wires did not get hot. So it would appear that I have an issue with the inlet plumbing or the outlet plumbing. I pulled the lower drain strainer and did not see anything obvious. The part that I think is odd is the inlet plumbing and how it combines the filter drain and the lower drain. I have attached a pic that hopefully shows what I am talking about. I am attaching the manifold I re-did incase you see something there as well.

RDspaguy Posted July 15, 2021 Report Share Posted July 15, 2021 There is a flow restriction or it's just too much pump for the plumbing. https://www.aquaflospapumps.com/aqua-flo-3-4hp-fmhp-fmcp-fmvp-tmcp-pump-impeller-91693551/ This might be all you need.

Ellisz Posted July 15, 2021 Author Report Share Posted July 15, 2021 Thanks. I think that is a easy solution to try. I am not sure it worked when I first tried it. Makes me think there is a blockage somewhere. There are 3 less jets working on the tub as the previous owner did not want to run ant more new pvc when he replaced all of the jets. That would support needing a smaller pump I suppose. Quote Link to comment Share on other sites More sharing options...
RDspaguy Posted July 15, 2021 Report Share Posted July 15, 2021 So, 12 jets to 9? That is a 25% decrease in return flow, plus a bigger pump. Sounds like a recipe for trouble to me. Quote Link to comment Share on other sites More sharing options...
Ellisz Posted July 15, 2021 Author Report Share Posted July 15, 2021 Agreed. I thought about adding them back in but pretty sure I would have to buy new jets, spa flex and another manifold. I did leave the option to add a manifold when I re-worked it but I would like to be somewhat confident that all else is good. When I got it, I thought the air valves were the only issue. Will have to see what that is like with a smaller impeller. Do the air valves affect flow or is it just adding air in the line for the spa feeling? Assume the latter...

RDspaguy Posted July 15, 2021 Report Share Posted July 15, 2021 The air enters the water at the jet body and has no effect on flow rate of the pump. Unless the air lines have been plumbed to the water pressure side lines somehow, but that would mean no air at the jets, and probably leaks at the air control valves.

Ellisz Posted July 15, 2021 Author Report Share Posted July 15, 2021 So that Aquaflo impeller should fit the Century Pump bn25v1 with a FMCP 1.0 HP 1.5" Pump Wet End (91040810-000)? This is just replacing the current impeller with that one? Anything thing else in there? Thanks Quote Link to comment Share on other sites More sharing options...
RDspaguy Posted July 15, 2021 Report Share Posted July 15, 2021 Well, century made the motor, the wet end is an aquaflo fmcp. The impeller is for an aquaflo fmcp. There is a wear ring, which should be fine to re-use, and a shaft seal which you might want to replace if the pump is not new or was ran dry. If it's new I would re-use it too.

Ellisz Posted July 21, 2021 Author Report Share Posted July 21, 2021 It has only been a day but with the smaller impeller, the tub is up to temp and responds to the jets control. The air valves still don't work but I am thrilled that it is working as it was supposed to when I set it up! Thanks for all the help RDspaguy! 1 Quote Link to comment Share on other sites More sharing options...

B Oakes Posted April 15, 2022 Report Share Posted April 15, 2022 Bought dreammaker spa brand new had to replace control panel before I could even use it the first time, ran good for a year then burned up 2 heater boards and even blew breaker box outside and one in the house and have had to replace jets on the lounger because they leaked real bad Trust me don’t buy one I know others having the same problem and not worth the money are a piece of junk… Quote Link to comment Share on other sites More sharing options...
