DIFFUSER, C1-271P STA-RITE (C1-271P)
Frequently Bought with this Diffuser
Used with the following Models:
I have a Duragas/Maxiglas seal plate model number C103-137P. What model numbers of diffuser and impeller go with that? It's for a 1.5HP single
speed spa pump motor.
Hi Kent, could you send us a photo of your motor? Please take a close up shot of the motor label. To supply photos simply click the reply link below and upload your photos. Once we get those photos we can make the proper recommendation.
My pump can't maintain suction on the supply line (2") and I've been told to check the "diffuser line" - to make sure it isn't clogged and that the air can escape. I've never seen such a line. Where is it? My pump is a 2hp P4 RA6G-188L.
Background: I pulled the motor and impeller housing out to check for debris and that it rotates freely, and even braced it and turned it on so I could see it spin under power. Looked (and sounded) fine.
Hi, Bruce. Pumps do not have a "diffuser line," it has a diffuser which funnels the water to the impeller. Debris can get caught in it if you pump strainer basket is damaged. You may have air in the filter which needs to be released allowing max water flow through your system.
Yeah, no debris caught anywhere. I have the filter control set on "waste" so water isn't going through the sand, and earlier disconnected the pump discharge to the filter control head to make sure nothing was clogging it. (re-connected now). Do you think there still could be air trapped in the filter?
Hi Bruce, Did you recently replace your pump with a new pump? Or is this the same pump you have always installed in the system, if it is the same pump then did this issue just recently start to occur? If so did you make any other changes to the system like plumbing changes or installation of new equipment? Could you post us a wide shot of your plumbing set up so we can see if there are any problem areas in your plumbing like excessive use of 90's?

Same pump that worked all last year. Just went to start it up this spring - no plumbing changes. The guys who built this were insane, trying to shoehorn all the equipment into such a tight area, with no room to work. I've never liked the 90-90 route from the skimmer line into the selection valve, but the joints appear solid.
Thanks for those photos! I really think the issue is the 90's those are really killing you with your total dynamic head. It may be a case where your pump has lost a bit of performance over the years and now is having trouble with the 90's. If you could eliminate one of the 90's on the suction side of the pump that would help you out a ton. I'm thinking you could cut out the 90 closest to the pump on the suction side and then lower the pipe which has the other 90 and then have straight shot into the suction port, you would need to rotate your 3 way diverter valve. Also if you could eliminate the 90 on the discharge side that would help but that looks like a much bigger project. I would suggest watching the Video we made on How to Fix Pool Plumbing Issues which does a great job of explaining the issue you are facing. One other easy fix you might try is to clean your pool filter. Let us know how it turns out.
Good Day! I have two questions
I have seen an imaging of the diffuser without brass ring. Is it real diffuser?
Can it work?
Thank your answer...
Hi, Roman. This Diffuser includes the Copper Ring. It will not work properly without the copper ring; I would not recommend that you purchase or use this diffuser without the copper ring.
Will this diffuser operate in a Sta Rite P4RA6G-188L pump? Do you carry the matching impeller? Thanks
