Why does my skimmer have no suction?

When your pool skimmer has no suction, the cause is most likely a blockage. This can put the entire filtration system of the pool into question, as there will be low water pressure.

What causes a pump to lose prime?

Leaks on the pump’s intake line as well as around the shaft seal of the pump housing itself can cause your pump to lose its prime. Obstruction-One possible reason your pump may be losing its prime is an obstruction or blockage in a line. Debris blocking the suction strainer or foot valve is the most common cause.

Why do my skimmers have no suction in them?

If the pump had normal water flow when the main drain was off then your skimmers have normal suction. It is the only place the water can be coming from into the pump. Suction into the skimmer is often not noticeable on the surface. Why do you believe that the skimmers have no suction?

What to do if your pool skimmer is not sucking?

If one of the skimmers isn’t sucking, you’ll want to remove the basket from the skimmer. With the basket visible, you’ll then be able to check if the flow control valve at the bottom of the skimmer is open. It should be almost closet, but there are some that have a valve that doesn’t obstruct the suction inlet.

How can I tell if my pool pump is suctioned?

If the water level in the pool is correct then you need to determine whether you are getting suction in your skimmer or skimmers. With the pool pump running on filter can you see water being drawn into the skimmers? If you can’t see water coming in then try putting a hand over one of the inlet ports at the bottom of the skimmer.

Why is my Skimmer not drawing in debris?

If you have plenty of suction but debris floating on the surface is not being drawn in, or doesn’t stay in, then it is probably a problem with the skimmer weir. See next section. This is an obvious one but it can be easily overlooked.

What to do if your Skimmer has no suction?

We also used the shop vac to push air through the lines and force any debris free. When doing this on the furthest skimmer from the pump house, the water came up through the closest skimmer no problem. When doing this same excercise on the closest skimmer, the water came up through the pool filter no problem.

What causes the pressure on a skimmer to drop?

Pressure on your filter will drop if there is a blockage there or in the pump basket or in the skimmer suction line. Pressure would be up if the filter was dirty. Even after cleaning a filter the grids could still be clogged with calcium buildup and cause the problem.

What happens when a pool skimmer is not working?

Pool skimmers are great for keeping the water clean, but it can result in more than a dirty pool when they’re not working properly. If one of the skimmers is clogged, it can make it hard for the water to pass through the filter.
