I've spoken to several pool maintenance companies but none have been to check the pool yet - only one is capable of doing a pressure test. The best way I can describe how a multi-port works is like a maze with revolving walls. But if you pull the switch out and stretch the hose then push the switch it works.

I put a couple of small leaves in the skimmer and they ended up in the pump basket, so no clog there. If you ask a pool professional “Why are my pool jets not working?”, you may receive a blank stare and a pause. I mean..baby pool with a ginormous spa on one end. Thanks - I'll take it off the filter and report back. We hope you enjoy the rest of the summer!Update – I called again this a.m. and was able to reach the tech. The pressure gauge is inexpensive and very easy to replace.We addressed the most popular causes of pool jets not working. Depending on the layout of your pool you might try unblocking the jet from the pool side using a probe or water compressor.

Generally, you won’t be able to tell unless you dig down to inspect those suspect spots.Just replace the pump, now only one jet is working.Did you purge the system of air after replacing the pump?I just recently purchased a replacement new 2HP Pool Motor (the same HP of my previous motor) for my inground Pool. The general rule is that 10 PSI above the normal operating pressure is considered high. I solved the problem by accident! New sand filter and jet was working great PSI was normal.

One jetpack has normal pressure and the other jetpack has low pressure. We could give a little more info on the multi-port valve if we know what brand of sand filter you have.

Unless you’ve recently lowered the horsepower or RPMs of the pump, low jet pressure is a problem and it needs to be corrected.The most common reason for weak jets is an air leak. When I turn the pump on the return jet has a nice strong output for about 10-20 minutes, then it slows to virtually nothing. I'm not very knowledgeable about the lines, pump, filter, returns...I take care of everything else, so I'm asking this for my husband, who's been the troubleshooter for the pool equipment, as he is with everything else.

Did you have any plumbing work done recently?

It is t just the lack of pressure in 4/6 spa jets but also the skimmer..we have to push the water in order to create a tornado…where do we go from here? However the water still looks cloudy I have no algae and the chemicals are perfect. It seems weird that two of the three Jets would work properly if there was a clog? We did. It’s a great product for sealing leaks in the plumbing. 6 of 7 are working flawlessly with excellent pressure coming out of them with no air bubbles.

They had accidentally left the 2 jets turned off. The contractor said normally the air intake is right next to the tub but it makes a lot of noise and wanted ours to be quiet and away.

If that's the case, it could be a design issue and/or a reduction in water flow that is putting all of the water through the other returns.
