Quick question about the relays in my Jandy Aqualink CP. I am assuming that each relay will only run one device. I know on the 12v out there are two connectors that are attached to the wire that goes to the specific device on the Jandy system. Why are there 4 connectors on the bottom half of...

I lubed the lid gasket last night, I will try the drain plug next. Do you think that the Impeller can cause any of this?

Sorry, not a big expert on all the Head Loss stuff :) but what you are saying is you are thinking that on the suction line, I am getting air coming in at either the pump or possibly the pipes?

Sorry about that. try the original video link. Thanks again for your recommendation.

mas985, As always, thanks for your honest and expert information. I was basing the 10-13 GPM for each jet on the average flow that the spec sheet was talking about. They were saying if you want a more Therapeutic type pressure then you would want around 20 GPM. I know I'm not going to get...

The pump itself is not reliable. I really couldn't tell you what the shape of this thing is in. Its old, may not have a good impeller and could be sucking air from someplace. With that said, I'm thinking about getting a new pump. I would like a recommendation on the HP, type and possible...

Thanks for the info. I wish I could upload the small video of the pump basket. I looks like a swirling tornado and not just a air pocket. Weird.

Folks, I had some time this weekend to work on a few things to see if I could get more pressure out of the jets on the spa. On thing I did was block off 6 of the 8 jets to see what it would do and I can say the pressure was nice and hard. I then unblocked another two for a total of 4 jets...

Thanks for that info. Just to be clear in my situation, if the PSI is below 9, then that's a problem? If so, would it be the Pump or Plumbing to look at. If it is reading 9-10 psi at the pump then what kind of pressure would you think I should be getting out of the Jet orifices (Thats without...

By how much do you think? I can remove the return valve and just leave the suction unless you think water will still back flow from the jets to the return line.

I would say the pump is below water level, but not by more then a couple feet. I don't really know why he used Valves. My guess is so that you can shut off the water flow if you need to change out the pump or do repairs. I know on my main pump, I have a ball valve on the main suction line...

I can take a pic tonight when I get home from Work but like I said, its very basic. The Valves are pentair 2". I have them wide open on each pipe.

As I stated, the pic is not of my actual pump. Its one I found on google that is close to the setup of mine. I have put circles about where the diverter valves are located on each line

mas985, Awesome. Thanks so much for clearing that up. I will work in it this weekend. As for as a picture of the Pump setup, I can get one for you however, its prety straight forward. There is only one 2" pipe going into the suction inlet and a 2" pipe coming out of the return on the pump...

You are correct about the original Jets and how they are connected. I was going to find some plugs and close off a couple jets to see how it did. I am also going to get a test bladder and see if there might be any clogs. mas985 requested to do a pressure test at the pump suction drain. Do...

mas985, I have taken the inserts out and still they dont give off much pressure. You Mention doing a pressure measurement at the pump return drain plug. How exactly would this be done (I'm a newby) is the plug the one on the front of the basket?

Ex Mguzzy, thank you for your response. When you mention your spa and having 4 jets, do you also have an air mixture with it. If so, that is my problem. The PB didn't plumb for air and I only have water going through them.

So let me ask you then. If you take the Jet insert out of the housing, there is just a 1" opening for water to come through. The housings where plumbed directly to the 2" PVC pipe. So really it would be like having 8 1" eyeball jet returns. In that scenario, how much GPM per return / jet...
