Pool inlet – choose the right nozzles and connections

Pool inlets, often called return inlets, return filtered water to the pool. Their placement and direction affect how the water moves through the pool. When buying new inlet nozzles, you also need to check the pool wall, the pipe connection, and which installation details are included.

What does a pool inlet do?

After the pump and filter, the water is returned through one or more inlets. They work together with the pool's skimmer and other connections. How many inlets are needed and where they should be located must be assessed based on the pool's size, geometry, and filtration system. More nozzles do not automatically provide better circulation if the flow is distributed incorrectly.

Choose according to pool construction

Inlets for Thermopool may have different gaskets and mounting details than inlets designed for liners, PP, or steel walls. For example, there are inlets for Thermopool with double gaskets (/products/inlopp-for-thermopool-dubbla-packningar-d50-lim-anslutning-abs). Check the product's dimensions and manual before cutting the hole. It is also important that the nozzle material is intended for the water environment.

Connection and flow

Compare pipe size, thread or glue connection, allowed flow, and any ball nozzles. Pahlén Classic (/products/pahlen-inloppsmunstycke-classic) is an example of a nozzle in the range, but an existing connection may require a different model. Always check the actual connection system.

Placement and direction

Directional nozzles can help direct the water's movement through the pool. But the best direction depends on where the skimmer, stairs, and other inlets are located. For new construction, the installation should be designed together with the pool structure and filtration system. When replacing in an existing pool, the original placement and the manufacturer's instructions should be the starting point.

Checklist before ordering

Measure the existing hole, connection, and thread or pipe diameter.

Specify whether the pool is PP, Thermopool, liner, or another construction.

Check the included gaskets, flanges, and locking details.

Ensure that the product is intended for your water and your construction.

Document the number of inlets and their placement in relation to the skimmer.

Frequently Asked Questions

Can I replace only the nozzle face?

It depends on how the inlet is constructed and which spare parts are available. Identify the model and connection first.

Are inlets and skimmers the same thing?

No. The inlet returns water, while the skimmer normally takes in surface water. Read more about pools with skimmers (/pages/pool-med-skimmer).

Does an inlet need to be directional?

It depends on the circulation plan. Follow the product's function and the pool's design.
