Aloha my packing gland is need of replacement, hoping to put a drip less in as soon as I dry dock. So for the moment there is more water coming in than I like and my bilge pump is not working. The pump runs when I hit the switch and if I put my hand over the hose at the start where the water is being sucked up it builds suction but the level of water dose not go down. I've checked the filter near the start of the hose the rest of it is hard to get to. Hoping for a trick or something that would tell me the hose is clogged before I stand on my head for a hour to find out. I am open to all advice thanks.
