This last week I replaced the Anderson KantLeak selector valve. It was hard to turn and filling my freshwater tank. Then two days later we had a leak from around my freshwater pump. So, I replaced the pump and screen. Now we have lots of air in the lines. If I turn off the pump or the city water, there is enough air in the line that water will continue to come out for 5-10 seconds. What is the best way to bleed all the air out of the system on a Torque M-290? we are currently living in it while looking for a new house so down time in the RV to fix something is not an option.
