We use the Shurflo 4048, along with a sound reducing hose kit, which makes this a very bearable pump for sound. On the Shurflo site, they indicate that this is the pump that replaced the Shurflo 5900. The specs indicate it will put out 4.0 gallons per minute and it is also a bypass pump, so that should reduce or eliminate surging when faucets are only cracked open. We never have an issue with water flow and never have any surging issues with this pump. Wide open, 4 gallons per minute in an RV is a lot of water, especially if you are dry camping, but even in a full hookup site,, we just don't have a need for any more water than this will produce in a non water site. Also, if the need came up, repair parts are available, as this is a current model.
