Questions About This Panel
How many manhole panels does a tank need?
Most tanks have one manhole panel in the roof. Large tanks or tanks with partitions may need more; we confirm this when we plan your tank.
Will this panel fit my existing tank?
It fits Mui Fatt and Y.T. Fibreglass sectional tanks. For a tank from another maker, send us a photo, the panel size and the bolt hole spacing so we can check before you order.
Can you replace the panel for me?
Yes. Our team can drain the tank, exchange the panel and fit new gaskets and bolts. See panel tank refurbishment and panel exchange.
For materials, bracing, installation steps, warranty and certificates, see the full FRP/GRP Sectional Panel Water Tank guide. SPAN and SIRIM documents are on our certificate page.
