You won't believe that I am back with the same problem from last year. All of the suggestions from you most experienced people have been tried and we still have the problem. The pump stops after hooking up the vac (Hayward). It is still our daughter's pool. The vac has been rebuilt...the hoses tested etc. We brought hose and vac and hooked it up in our pool and it runs just fine. Tries to climb out of the pool. This is the same system that ran great in that pool for years. We had all the lines and valves replaced to insure there were absolutely no leaks. What I am getting at is, if a professional comes out to pressure test the line and finds a problem, how do they, or do they, even solve the problem, or how do they determine what the problem is if the pressure is not good? thanks for anything you can suggest

There are no air leaks in hose, or around valves or pipes. Pump runs like crazy until the vac is hooked up. Today we even tried running it with just the full length of the hose, but without the vacuum attached. It ran and ran, but then as soon as the vacuum was attached it stops pumping. Any ideas?

Thanks Paul....tightening the pod was the answer. Appreciate your help. Donna

I haven't yet solved the problem at my daughter's with her pool and now I have a problem with our pool vac. It is a hayward pool vac that has started going in circles, only to the left. The wings are new and the feet are new. It also has a correct lead hose. Any ideas?

IMO, If you don't use it alot, use of co2 is cost prohibitive, and very dangerous if you don't buy a regulator (cost prohibitive part). Those things can have in excess of 1000 pounds of pressure on the valve. To give you an example, 10 pounds pressure can hurt if something blew apart and hit say your hand. There are guys that say "I open the valve only a little and that keeps the press low". They are right, Until what your blowing hits the obstruction then the pressure in the pipe tries to equalize with the bottle Thats when the drainjet comes back at you. Please don't buy a co2 bottle. AquaTechPool is right, call a pool guy. K~I won't pursue that route...I'll call a pool guy. Thanks

Tell me about using the co2.....where do I get one? how do I use it? where do these "items" emerge? thanks

We're on our way over there again today and will see what it does..... Well, you know what? We have finally decided that the trouble has got to be somewhere in a submerged line. We have tried all these great suggestions and nothing worked. Now what? How do you find and fix a problem like this? We've already used one of those black expanding blower attachments (whatever it's called). Right now it's running on just the main drain, so except for the fact that the vac can't be used, it's ok. Thanks for all the help..... Maybe I need a plumber?

We're on our way over there again today and will see what it does.....

It is a vac head... tried several things today....it actually stopped running without the vac being plugged in...also tried running water over the fittings to see if we could detect water going in, to see if maybe that was the site of possible air induction....nothing is solving the problem.... will keep up the trial and error....also checked the bottom of the skimmer, per your idea and it was not black....also ran it without the vac head being attached and it still stopped.... thanks for trying....

Thanks... We're working on it....heading over there (the pool is at our daughter's) and to the pool store. Have also been looking at the Hayward manual for some ideas....the strange thing is that this is not a new vac or hose or anything....we've been doing the same maintenance and problem solving for 10 years and this is the first time for this exact situation and the first time to not be able to solve the problem. We'll keep trying....

Thanks for your input.... It is a Hayward Navigator and I am reading up on several issues regarding lead hose section....gauges etc...

Thanks for trying....no suggestion seems to work. It is very frustrating...the idea about the hose twisting and exposing the leak was exciting, but we put it in the pool, being careful to get all the air out, and kept it from "going" and it did the same thing.....just stopped after a couple of minutes! Anyone know where I can get a second hand, old fashioned, manual vacuum!?! About to give it up. Thanks again....I still look like my emoticon!

I have completely rebuilt my pool vac and tested all the hoses. It will run strongly, with no problems, for days and days on either the: 1. skimmer 2. vacuum connection 3. main drain. However, when I connect the pool vacuum hose, it only runs great for about 2 minutes. At that time the water flow into the pool is greatly reduced and the pool vac completely stops. There doesn't seem to be a great amount of air in the system. Does anyone have any ideas? Thanks very much
