The use of a hosepipe connected to the mains supply to fill a domestic swimming pool is prohibited unless it is necessary as part of its construction, significant refurbishment, or for a particular health and safety purpose. Examples of significant refurbishment include works that might entail major alterations to the shape or size of the pool, or to its immediate surroundings, repairs of significant leaks, or the installation of a completely new liner. Minor repairs, such as the replacement of tiles, would not qualify as significant refurbishment. Ideally, water from the domestic pool to be refurbished or repaired should be retained in a temporary structure, subject to any space restrictions on site and depending on the suitability of the water being
retained. The first fill of the pool should only be filled by the specialist business contracted to carry out the work. Thereafter, the pool cannot be topped up or filled by a hosepipe connected to the mains supply.
