The A.L.D.A. has to be replaced. The screws are not coming out and sick of messing around with it. I spent a half hour using an impact driver with a heavy hammer and all I did was mess up the threads. Rather just get one that doesn't leak and be done. I could have saved the $30 for the impact driver and put it towards another A.L.D.A.. So if anyone has a leak free unit, please contact me.
