About Spa Pump Water Inlet/Outlet Nuts (B/C Coupling)

Lay-Z-Spa B/C Coupling is a replacement for a missing or broken B or C coupling.. Without a B/C coupling, your Lay-Z-Spa will stop circulating water efficiently.


This is because the Lay-Z-Spa coupling is used to connect the B or C pipe on a filter pump to the inlet and outlet on a Lay-Z-Spa. If your existing B or C coupling is badly damaged, you're likely to notice water drizzling out of the pipes and draining your Lay-Z-Spa.


If left too long, this can slow the flow of water and start to affect its cleanliness. This makes the B/C coupling one of the most important Lay-Z-Spa parts to have in full working order. As a result, we suggest keeping a couple of couplings as Lay-Z-Spa spares.
