Hi,

I've been advised to plug my jets to check for leaks to see if it is the plumbing or the liner in my pool and I have a number of friends who would like to do the same thing.  My question is : do all return jets have the same size eye, nozel and retaining ring  thread?

Thanks in advance for any help you can give

Hello Oliver,

 

No they do not.

 

But is easy to block them, Just use a piece of Glad wrap and screw the ring back on.

Some return jets don't even have threads.  Threads or not, the easy way to do this is to get a special plug from Home Depot or any other hardware store that is used to plug drain plumbing for tests.  These tools have a center rubber plug with a screw.  You put the plug into the port and tighten the screw which expands the plug and makes the seal.  They+- come in regular pipe sizes.  This has worked very well for me.

If nothing is obvious, including any lines for draining or backwashing, try to find out if it leaks more with the pump on, or off. Measure water loss with the pump on for a day or 2. Then turn it off for the same amount of time and measure the loss. If it loses more with the pump on, it is most likely to be in a pressure line. More loss with the pump off indicates a suction line. No difference indicates the pool itself including around fittings, lights or even a hydrostatic relief valve. Grab some test dye from your local store. With the pump off and the water still, slowly squeeze a bit of dye around suspect areas to see if the dye tends to be drawn out of the pool. You need to keep everything very still though unless you have a large leak. The water leaking out from the pool will draw some dye with it and you have found a leak. Hopefully the only one The above at least gets you going and will save a bit of time (hopefully) when you call someone in to deal with it.
