Considering this, do I need a circulation pump on my hot tub?
Every hot tub needs a pump that can powerthe jets and circulate the water. This means it needs bothhigh and low speeds, which are measured in revolutions per minute(RPM).
Likewise, how does the spa work?
A spa works in three stages: Water is drawn fromnear the surface of the spa and goes through a filteringprocess. The heated water is then pumped into the pool through thewater jets. Many of today's spas use an air induction systemthat mixes air with water to increase the thrust of thewater.
Cost to Repair a Hot Tub Pump You can also just replace the entire jetpump for $200-$300. Circulation pumps, aka CircPumps, which run low speed most of the time, are replacedfor $150-$200.
