FAQs

What is the purpose of the 50mm water seal?

The 50mm water seal creates a barrier of water in the trap that prevents unpleasant and potentially harmful sewer gases from rising through the drain and entering your bathroom.

Can this shower trap be used with any shower tray?

This trap is specifically designed for shower trays that have a 50mm diameter waste outlet hole. It may not fit trays with different sized outlets.

How do I clean the McAlpine STW2M-95 shower trap?

The trap features a removable body. Simply unscrew or detach the lower part of the trap, clean out any debris, rinse, and reassemble. This can usually be done by hand.

What does 'Universal Outlet' mean?

A universal outlet means the trap can connect to a variety of waste pipe types and configurations, offering flexibility during installation. It often includes adapters or a design that fits common pipe sizes and connection methods.

What materials is this shower trap available in?

The McAlpine STW2M-95 is available in White Plastic, Chrome Plated Plastic, or Chrome Plated Brass options, allowing you to choose one that best matches your bathroom's aesthetic.

What is the thread size for connecting to other fittings?

The outlet thread size is 1.5" BSP, which is a standard size for plumbing fittings.

Does it come with the bend shown in diagrams?

Yes, the product is supplied with a 95° bend that has a BSP coupling nut connection on one end and is designed to connect to a 1.5" multifit waste pipe on the other.

Troubleshooting

Water is draining slowly from the shower.

The trap may be partially blocked. Remove the trap body and clean out any accumulated debris. Check the waste pipe for any obstructions.

Unpleasant odors are coming from the drain.

Ensure the 50mm water seal is present and hasn't evaporated (this can happen if the shower is unused for long periods). If the seal is intact, check that the trap body is correctly seated and the outlet seal is secure.

The trap is leaking.

Check all connections for tightness. Ensure the seals on the shower tray outlet and the waste pipe connection are correctly fitted and in good condition. Re-apply sealant if necessary.

Difficulty connecting the outlet to the waste pipe.

Confirm the type of waste pipe you are connecting to. The universal outlet is designed for flexibility but may require specific adapters or solvent weld cement depending on the pipe material (e.g., PVC, ABS).

Pros and Cons

Pros

  • Effective 50mm water seal prevents odors.
  • Universal outlet offers installation flexibility.
  • Easy maintenance with a removable trap body.
  • Multiple material and finish options available.
  • Designed for standard shower tray installations.

Setup, Compatibility & Care

Setup:

  1. Ensure the shower tray has a 50mm waste hole.
  2. Apply plumber's tape or sealant to the BSP thread of the trap if necessary, though often a good seal is achieved with the provided nut.
  3. Connect the trap to the shower tray waste outlet, ensuring a watertight seal.
  4. Connect the universal outlet, using the 95° bend if required, to the main waste pipe.
  5. Test for leaks by running water through the shower.

Compatibility:

  • Suitable for shower trays with a 50mm waste hole.
  • The 1.5" BSP thread on the outlet allows connection to standard fittings.
  • The universal outlet can adapt to various waste pipe configurations (e.g., push-fit or solvent weld, depending on pipe material and adapters used).

Care:

  • Periodically remove the trap body to clean out any accumulated hair, soap scum, or debris. A simple rinse under a tap is often sufficient.
  • Use a soft cloth and mild detergent for cleaning the visible chrome or plastic components. Avoid abrasive cleaners that could damage the finish.
