Overview

Whether you’re replacing a pump like-for-like or retro-fitting a new model pump, it’s crucial to get the correct sized union fittings to minimize the possibility of needing to change any plumbing. This guide will explain the key components of a pump union and how to measure them accurately.

Tech Dave’s Top Tip

If you need to remove the union from the pump, make sure to drain the spa or close the isolation valves before unthreading it.

Union Tail Piece

The union is made up of 3 pieces: the Collar, the Tail piece, and the Rubber seal. The collar is the part which threads onto the pump inlet or outlet. The tail piece is used to glue onto the pre-existing spa pipework.

Measuring the Unions Collar Internal Diameter (ID)

If it’s easier to access the unions, measure across the widest point of the inside of the collar (Internal diameter, thread to thread), as shown on the diagram.

If the ID of the collar is 62mm (+/- 1mm), you’ll need a 1.5 union
If the ID of the collar is 78mm (+/- 1mm), you’ll need a 2.0 union
If the ID of the collar is 92mm (+/- 1mm), you’ll need a 2.5 union

Measuring an Existing Pump Inlet & Outlet

If it’s easier to access the pump’s inlet and outlet, measure across the widest point of the inlet/outlet (thread tip to tip).

If the pump inlet/outlet (thread tip to tip) measures 62mm (+/- 1mm) across, then it fits 1.5 Unions
If the pump inlet/outlet (thread tip to tip) measures 78mm (+/- 1mm) across, then it fits 2.0 Unions
If the pump inlet/outlet (thread tip to tip) measures 92mm (+/- 1mm) across, then it fits 2.5 Unions

Measuring the Union Tail Piece

The most common pipes used in spa pools are 1.5, 2.0, and 2.5. In the pool and spa industry, the term 1.5 refers to a pipe that measures 48mm in outer diameter (OD) and has a 1.5 internal diameter (ID). For example, a union tail piece with a 48mm internal diameter (ID) is compatible with a 1.5 pipe.

If the union tail piece ID measures 48mm (+/- 1mm), it is compatible with 1.5 pipe
If the union tail piece ID measures 60mm (+/- 1mm), it is compatible with 2.0 pipe
If the union tail piece ID measures 72mm (+/- 1mm), it is compatible with 2.5 pipe

FAQ

Q: Where can I find the specification table for my pump?

A: The specification table can be found on every pump product page on Spa Supplies.

Q: How do I convert the union sizes to pump specifications?

A: Once you have confirmed the required union size for your inlet and outlet, locate the specification table on the pump product page. Compare your union sizes to the Inlet and outlet union size listed in the table.

Q: What is the maximum horsepower (HP) of the LX WP-300-II pump?

A: The maximum horsepower (HP) for the LX WP-300-II pump is not specified in the user manual.

Q: What are the low speed and high speed settings for the LX WP-300-II pump?

A: The low speed and high speed settings for the LX WP-300-II pump are not specified in the user manual.

Q: Is a plug included with the LX WP-300-II pump?

A: The user manual does not mention if a plug is included with the LX WP-300-II pump.

OVERVIEW

Whether you’re replacing a pump like-for-like or retro-fitting a new model pump, it’s crucial to get the correct sized union fittings to minimise the possibility of needing to change any plumbing. It can get confusing because many pump unions are described using imperial sizes, like the common 2.0” specification. However, the actual thread size does not measure 2.0”. When evaluating pump unions and their sizes, ensure you’re looking at the thread size rather than the union tail piece. This guide will explain the key components of a pump union and how to measure them accurately.

UNION COLLAR & TAILPIECE

The union is made up of 3 pieces ; the Collar, the Tail piece and the Rubber seal. The collar is the part which threads onto the pump inlet or outlet. The tail piece is used to glue onto the pre-existing spa pipework.

MEASURING THE UNIONS COLLAR INTERNAL DIAMETER (ID)

If it’s easier to access the unions, measure across the widest point of the inside of the collar (Internal diameter, thread to thread), as shown on the diagram.

If the ID of the collar is 62mm (+/- 1mm), you’ll need a 1.5” union
If the ID of the collar is 78mm (+/- 1mm), you’ll need a 2.0” union
If the ID of the collar is 92mm (+/- 1mm), you’ll need a 2.5” union

MEASURING AN EXISTING PUMP INLET & OUTLET

If it’s easier to access the pumps inlet and outlet, measure across the widest point of the inlet/outlet (thread tip to tip).

If the pump inlet/outlet (thread tip to tip) measures 62mm (+/- 1mm) across, then it fits 1.5” Unions
If the pump inlet/outlet (thread tip to tip) measures 78mm (+/- 1mm) across, then it fits 2.0” Unions
If the pump inlet/outlet (thread tip to tip) measures 92mm (+/- 1mm) across, then it fits 2.5” Unions

MEASURING THE UNION TAILPIECE

The most common pipes used in spa pools is 1.5”, 2.0” and 2.5”. In the pool and spa industry, the term 1.5” refers to a pipe that measures 48mm in outer diameter (OD) and has a 1.5” internal diameter (ID). For example, a union tail piece with a 48mm internal diameter (ID) is compatible with a 1.5” pipe.

If the union tail piece ID measures 48mm (+/- 1mm) , it is compatible with 1.5” pipe
If the union tailpiece ID measures 60mm (+/- 1mm) , it is compatible with 2.0” pipe
If the union tailpiece ID measures 72mm (+/- 1mm) , it is compatible with 2.5” pipe

PUMP EXAMPLE

Once you have confirmed the required union size for your inlet and outlet. Here is an example on how to convert these measurements into pump specifications. The below table can be found on every pump product page on Spa Supplies. This example is the LX WP-300-II which has a 2.5” inlet and a 2.0” outlet. Locate the specification table and compare your union sizes to the Inlet and outlet union size apasupplies-WP-300-II-Massage-Pump-
