    Product Description

    90 Litre GRP Water Tank

    Manufactured to meet BS7491 Parts 1 and 2, using the highest quality GRP materials, ensuring a long service life with minimal maintenance requirements. Full WRAS approval. Grey colour as standard (other RAL or BS colours are available at additional cost). Only materials of the highest quality are used along with a highly efficient manufacturing processes. This combination ensures that these tanks are of the highest quality available.

    All internal surfaces, including the lid, have an Isophthalic white gel coat layer which provides a clinical smooth surface which will not support the growth of microbiological organisms. This gel coat layer is reinforced by the main GRP laminate, which provides the main structure of the tank body. The materials used are of the highest quality and applied with exacting production standards to assist in prevention of osmotic blistering. After the CFC free PU foam insulation is fitted, the GRP outer skin is then applied. This ensures that the insulation is fully encapsulated and protected from external conditions.

    Where access is a limiting factor and our one piece GRP tanks are unsuitable, a two piece tank could do the trick. These tanks are manufactured in two or more horizontally split sections, which are then assembled once the restriction has passed. In a nutshell, and a one piece tank in two or more bolt together sections. All the components including sealant and fixings for the joint flange are supplied with the tank. The assembly of this range of products could not be easier and should not prove difficult for any competent mechanical services engineer.

    The Encapsulated Baseboard will come moulded into the internal base of the tank to become part of the tank's construction and overall strength of the base. This will benefit the tank if it's on uneven surfaces or positioned raise supports. It will not come supplied as a separate item. If the encapsulated baseboard is selected, please note this will add 30 mm to the external height of the tank.

    What is a GRP tank?

    Glass Reinforced Plastic tanks are made from high quality GRP material manufactured to BS EN 13280:2001, are suitable for all cold water applications, insulated tanks are also suitable for external applications, and are fully WRAS approved.

    Sizing a float valve for my GRP tank

    A float valve will usually be sized to suit your incoming mains water supply, so if you have a 25 mm incoming mains you will need a 1” float valve. If we supply the float valve with your tank we will size and supply the overflow to suit this.
