Water in Oil Tank

[Best]

No it won't wreck your pump as long as you don't leave it sat full of water after use.

Didnt know that. I have an electric pump which I have tried to keep pumping clean oil & hasn't had much use, but once it didn't start until a few taps. I have thought a drum of red diesel would be good to use the pump on, after it has been used draining a tank.

I have just done a similar job today. I couldn't start it syphoning as little in tank so too high a lift to start it & too risky, so I just filled the hose (with 5ft copper with a bend on end) & let it flow. Was no problem. Had to flush oil pipe, oil burner & renew burner oil pump, nozzle, oil hose, plus new filter at tank.

I find that the usual source of water ingress is from the filling point - over the years with the fuel companies constantly screwing and unscrewing their hoses on it, it tends to work loose allowing rainwater to get around the seal. I re-do them with silicone sealant.

I find this a lot, a real pain. The washer around the fill point perishes and falls apart leaving a lovely 4mm gap under the filler point, rain pours through and collects in the bottom of the tank. As WHPES says, silicon the bugger. I check it on each service I attend.
