Square drain for a concrete swimming pool

Square drain for in-situ swimming pools

The 2″ square drain for a concrete swimming pool It is designed to be installed at the bottom of the pool during the construction or refurbishment of a concrete swimming pool. It forms part of the hydraulic circuit and can assist with drawing water from the lower areas, recirculation or draining, depending on the design specified by the professional.

Trypool confirms that the body is made of ABS and has an anti-UV coating. The website currently uses the reference TRYSUMC, whilst the catalogue identifies the square concrete drain with the code SUMC and a 2″ connection. Both codes should be checked before the product details are finalised.

Square lid

The square cover is designed to cover the access point to the drain body and must remain securely fastened whilst the swimming pool is in use.

The system must not be started up if the cover shows any of the following:

• Breaks.
• Deformations.
• Missing screws.
• Movements.
• Clearances.
• Damage that could affect how securely it is fixed.

Current information does not confirm that the lid has an anti-vortex design. This feature must not be included in the name, description or images without the relevant documentation.

Installation in concrete

As this is a concrete mould, the body must be positioned before the formwork is fully completed. Installation must ensure that it is correctly levelled and prevent the final finish from hindering the removal of the cover for future inspections.

Before pouring concrete or sealing off the site, the professional must check:

1. Position of the drain.
2. Height relative to the final finish.
3. Connection orientation.
4. Pipe diameter.
5. Leak-tightness of the joints.
6. Walk to the control room.
7. Compatibility with other extraction points.

Hydraulic sizing

The 2″ connection must be incorporated into a correctly sized circuit. The permissible flow rate cannot be determined solely on the basis of the connection’s nominal diameter.

The pump capacity, pressure drops, pipe length, valves, elbows and the overall layout of the system must also be taken into account.

Until the technical data sheet is available, no maximum flow rate, suction speed or working pressure should be published.

Maintenance

Maintenance should include the regular removal of waste, checking the lid, checking the screws and carrying out a visual inspection of the ABS.

If a crack, deformation or leak is detected, the system must be shut down until a professional has inspected the installation. Keeping the cover clean and securely fastened helps to maintain the system’s performance and safety.
