PWTAG Technical notes are updates or new material for the standards and guidance given in the PWTG book, Swimming Pool Water and the PWTAG Code of practice and should be read in association with these publications.
This technical note on installation supplements the information in the PWTAG book Swimming Pool Water: treatment and quality standards for pools and spas.
