Set Up of Jets in an Inground Pool Cleaning System


One of the challenges of owning an inground pool is keeping the water clean at all times. Rain and runoff easily enter a swimming pool, clouding the water and requiring a filter to remove bacteria and debris. An inground pool's filter return jets, or the jets on an automatic cleaner, deliver will clear water only when they're set up properly.

Jet Types

  • An inground swimming pool can benefit from two different types of jets that inject clean water into the pool. The first is the return jet, which uses the pool's pump to force clean water that has passed through the filter back into the pool. The return jet is the counterpart of the drain, which pulls dirty water out of the pool for filtration. The other type of cleaning system jet for an inground pool is a jet attached to an automatic cleaning system. This type of cleaner acts like a portable filter, taking in water as it rolls along the bottom of the pool ad ejecting it back into the pool through jets.


  • An automatic inground pool cleaner's jets are immoveable and located away from its intake mechanism. This ensures that clean water isn't sent through the jets and immediately captured for additional filtering. A pool's return jet is typically located in the pool wall in the general vicinity of the filter and pump. Some larger pools have multiple return jets. Selecting locations for jets that are closer to the pump and filter allows you to use shorter pipes and makes installation easier.


  • Cleaning jets on an automated inground pool cleaning system are installed in the cleaner head when it's built and don't require adjustment unless they break or become clogged. However, the jets that you build into your pool to return clean water from the filter must be installed when the pool is built. The pipes that lead to pool jets can be buried in the deck cement, though placing them below access doors ensures easy replacement and cleaning. The pool's concrete form and liner must be poured and cut, respectively, to allow for the jet or jets to enter the pool basin.


  • Inground pool jets, along with drains and intakes, ensure that water is filtered regularly and kept clean. However, this doesn't eliminate the need to add chemicals periodically to kill bacteria and keep the water's pH level properly balanced. In addition, if you don't keep your inground pool covered, debris from the air can settle on the water's surface where the filtration system can't reach it. This type of debris requires manual removal with a skimmer.
