Winter pool plug – for skimmer, inlet and pipes
A winter plug can be used to seal selected connections when closing the pool for the winter. But different plugs serve different purposes: some are made for skimmers, others for pipes or inlets. The right size and the right procedure are more important than choosing a plug that just looks like it fits.

Where are winter plugs used?
It depends on the pool's construction and the manufacturer's winter instructions. A plug may be needed in a connection that needs to be protected after the water has been handled correctly. This does not mean that a water-filled pipe is automatically frost-proof. For pools with multiple inlets or separate valves, the piping should be documented before work begins.
Skimmer plug or pipe plug?
The Gismo winter plug for skimmers (/products/gismo-vinterplugg-for-skimmer) is a specific product type for skimmers. The conical winter plug for pool pipes (/products/konisk-vinterplugg-for-poolror) is another solution. Always check the dimensions, thread or sealing principle and the manufacturer's intended use. The products are not interchangeable simply because both are called winter plugs.
Start with a plan for the piping system
Find out where the pump, filter, skimmer, inlets and any shut-off valves are located. Identify which pipes can be drained and which must be handled using a different method according to the pool's manual. The pool's water level should not be lowered casually: it may need to be maintained at a certain level for structural reasons.
Check before you order
Skimmer or inlet model and exact connection dimensions.
Whether the manufacturer requires a special plug, seal or O-ring.
How the winter closure should be carried out in your specific piping system.
Whether the pool has special solutions, such as underwater connections.
Whether the plug can be installed and removed without damaging threads or seals.
Frequently asked questions
Can I just plug a pipe filled with water?
No, a plug in itself is not proof of frost protection. Follow the pool and component manufacturer's instructions for draining and winter closure.
Does the same winter plug fit both skimmers and inlets?
Not generally. Dimensions and sealing principles differ.
Is a winter plug needed if the pool has a winter cover?
These are two different functions. A winter cover (/pages/vintertackning) protects the pool opening, while plugs are used in specific connections when the instructions require it.
