Captevan, You must have seen the Volvo with the strainer on the suction side in the conference center as the one on display at the brokerage show had it on the pressure side and when I asked the guy he kind of huffed and puffed but then admitted that the newer models came with the a metal top and were on the suction side. Capt. Bill11, I think it was CaptJ who advocated the use of a large pump, large pump or small pump with shore or genset power would obviously make no difference to the battery bank, I was saying that if you lost the AC power then there would be a problem. Also why have an over size pump for every day use, they had the hydraulic one for emergency's but as they had limited alarms, external audio & visual they being ashore had no way of knowing the boat was flooding. I say a big flashig light, loud alarm, an alert system thru' your phone and regular testing of the whole system would be the way to go. I was on a 160 footer at the show and actually took a photo of the board in the engine room that showed the dates of the last test of the bilge & fire pumps.
