FAQ

This dispenser is commonly used as a replacement for select Coleman SaluSpa and Lay-Z-Spa inflatable hot tubs and spas. The part numbers associated with this dispenser are P05345 and P03821. Because fitment can vary by spa series, it is best to match your existing dispenser number and connection style to P05345 or P03821 before ordering.
This replacement chlorine dispenser is associated with part numbers P05345 and P03821. If your original dispenser is marked with either of those numbers, this is the correct part family to compare against your existing unit.
It holds spa sanitizer tablets and meters chlorine into the water gradually to help maintain water balance and cleanliness. On inflatable hot tubs and similar spas, this type of dispenser is used to provide more controlled chemical distribution than simply placing tablets directly in the water.
Common signs include a cracked housing, a cap that no longer seals properly, difficulty adjusting chemical flow, tablets dissolving too quickly or too slowly, or inconsistent sanitizer levels even when the spa is otherwise functioning normally. Physical damage and poor flow control are the most common reasons for replacement.
Installation is usually simple and typically takes only a few minutes. In most cases, no special tools are needed. Remove the old dispenser, check that the connection area is clean and undamaged, and install the new unit in the same orientation. Before use, verify that it is seated properly and that the flow adjustment, if present on your version, moves freely.
Before installation, inspect the spa’s dispenser connection point for cracks, debris, or scale buildup that could affect fit or water flow. It is also a good idea to confirm that your water chemistry is being tested regularly and that you are using the correct sanitizer tablets recommended for your spa. If chlorine levels remain unstable after replacing the dispenser, also check tablet size, water circulation, and filter condition.
