The plot thickens
Am testing his machine in stages
1, Put water in both tanks no leaks - machine was not switched on = no drips
2, Switched heater and pump on and just primed it (no vacs) and ran the water through and back into clean tank = no drips
3, Sealed waste pipe and top of waste tank and connected hose and hand tool and switched vacs on and cleaned spare offcut = dripping after about 1 minute down the centre - drip every second or so
4, Switched off vacs and left the heater, pump on and the hose and tool connected but stopped cleaning = still dripping 15 mins later
Does this mean its the pump leaking?
Thanks in advance
