Underground pool-skimmer pipe is blocked-how to unblock it?

Postby engqulo » Tue 17 Mar, 2009 11:47

I have the same problem as "DanO" described in his May 18, 2007 post - there's suddenly no suction into my pool sweeper line. The skimmer sucks great, but not the sweeper. How do I unclog it? My Hayward Navigator is hooked up to the sweeper line but with no suction, it won't work and the algae/dirt is building up on the pool floor. I have house guests coming this weekend! Help!

My Pool: it's about a 12,000 gallon oval-shaped pool, max depth 5 feet. Plus a spa/hot tub that waterfalls into the pool. I have a 1/2 HP pump and a Hayward Navigator pool vacuum connected to the sweeper line.

Since my main drain line was not clogged (just the pool-vac line), I switched the jandy valve fully to the main drain line, so the vacuum line was totally shut off. I noticed, even after thoroughly backflushing my sand filter, that the pressure seemed a few pounds low (read at the gauge on the top of the filter). Since I had replaced the pump impeller a year ago, I suspected there was something going on in there that wasn't good, so I took apart the pump and had a look. It turns out there were a number of palm seeds (small, hard, 1/4"-diameter spherical seeds) jammed in the impeller vanes. I cleaned out everything that I could, and then used a small thin screwdriver to remove all of the seeds. After putting everything back together, I gained back the 2-3 pounds of pressure that was missing.

Then I removed the pool creature's hose from the pool, propped open the vacuum line outlet cover (in the pool), and switched the jandy valve to 100% vacuum (main drain line completely shut off, in other words). Turned the pump back on, and still not much suction, but I heard a big "gurgle" in one of the pipes that I didn't expect.

After shutting off the pump, I started the process of using the Drain King. I first took all the screws out of the top of the jandy valve and removed it (to expose the vacuum line's pipe). I immediately noticed a small strand of fan-palm tree debris hanging out, and on further inspection with a flashlight, I could see a large snarled mess of this palm-tree stuff stuck at a 90-degree bend in the vacuum line pipe (right before it went into the ground). I have a claw-type "grabber" device that is used for picking small parts (screws, etc.) out of tiny crevices. It's about 30" long, so I used it to grab hold of the big snarled clog that was at the 90-degree bend in the vacuum line. I managed, after several tries, to get a good hold on it, and extracted the whole thing. Put the jandy valve back together, et voila, LOTS of vacuum suction! Problem solved.


Have you tried to use a hose or compressor to force the blockage backwards into the pool?

In the interim you could hook your Navigator up to the skimmer.

I had same problem with clogged skimmer line. No water flow whatsoever. Main drain line works fine. Problem has existed for at least 4 months. I turned off pump, closed main drain line valve, removed pump filter top and basket, put garden hose (no attachments), in line through filter assembly and turned on water. The line filled with water and overflowed the filter assembly. I let the water run probably no more than 2 minutes. Removed hose replaced filter basket and top, opened main drain valve and turned on pump (I did have to stop one time and prime pump with a bucket of water. After water filled main sand filter I backwashed and then did a Waste flush for about 10 seconds and returned pump to normal filter mode. The backwash and Waste flush may not have anything to do with it but I just documenting what I did. I went back to skimmer basket and the water flow was completely back to normal. Just in time because in South Carolina we are into the yellow pollen and all the other Spring stuff season. Wife asked me if I looked in pump filter basket to see what was in it. Told her no because I'm not stopping the skimmer and pump until at least tomorrow and let that puppy work. :D

I HAVE A HAYWARD VACUUM THAT KEEPS GETTING CLOGGED BY LEAVES FROM A TREE OVERHANGING THE POOL, WHAT CAN I PURCHASE OR DO TO STOP THE LEAVES FROM CLOGGING AT THE BOTTOM OF THE VACUUM. I NOTICE THAT ALOT OF PEOPLE SAY GET A LEAF CATCHER BUT I DONT SEE HOW THAT WILL STOP THE CLOG FROM OCCURING AT THE BOTTOM, ANY HELP WOULD BE GREATLY APPRECIATED. THANKS

Just a heads up to all. This is what ive done in the past and it hasnt failed me yet. It takes some plumbing and then replumbing but its worked 5 out of 5 times for me. What i do is cut the pipe coming into the inlet of the filter/circ pump and cut the return coming out the filter/circ pump and basically just plumb it backwards so that it is sucking from the return and returning through the inlet. If your skimmer is clogged isolate the skimmer line by shutting the main drain valve and vice versa.

Nice one mdpool

That just might work. What are the risks of bursting a pipe though?

This here is what works good. Should be able to get at "super" hardware stores. I think it's called drain jet or something like that.

At rest...
