You would do this by taking the pipe off of the water tank and placing it in the bucket of water. Restrictions on the inlet side of the raw-water pump.
The greater the distance a pump has to pull the water the lower the flow rate will be.
Boat fresh water pump troubleshooting. Manual fresh water pumps like this basic model from Whale are generally easy to troubleshoot and rebuild. Remove the fresh water supply hose from the hand pump to see if water is flowing from it. If water flow is not present you can try moving the hose end to a lower point in the boat or simply try sucking on it like a straw.
Fresh water pump problems If its air in your system fill your freshwater tank and run each faucet for a couple of minutes to get the air pocket out. Most water pumps are self priming so that should not be an issue. If it was a leak you would hear the pump cycle on and off periodically.
No water when you turn on the tap. Its more than likely its your freshwater pump not running. Ben opens one up and shows you the common problems and how to.
You might need to fill the tank almost full before the pump will prime and start pumping. The water level in the tank has to be higher than the pump. If the water tank is full and you can hear the pump running and no water is flowing it probably means the pump has failed.
Sometimes the strainer is before the pump and it cant get water to it as they do get plugged. Had one that the owner replaced the pump on oncestill no pressuerturned out his water heater had split a tube due to poor winterization. The pump would runbut the water would exit through the boats exhaust sysymtherefor no leaks inside the boat.
I ran water out of all the faucets to purge any possible air. The strainer is clean. The water tank is almost full and the fill cap is closed.
There were no pipe leaks apparent. I reset the breaker several times and also turned off the breaker for several hours. When the breaker was turned back on I still had continuous running of the pump.
I hhave been off the boat a few months when I returned the Water Systems seem to be working okay and then it started acting up. I have a fairly expensive jabsco duel pump and accumulator tank system. The problem is I have very low water flow and lots of air in the.
I also noticed that when the pump is running it is pushing air back into the fresh water tank and the hot water heater. Check the inlet side of the pump make sure water is running freely to the point of the pump ie make sure nothing is restricting the water from the tank. I actually found a butt connector stuck in the water.
When this occurs the water flow is disrupted causing trouble to the engine. Take a thin piece of wire and run it through the output. Wiggle it around to dislodge any debris that might be inside.
The flow of water from a JABSCO PAR-MAX multi-diaphragm pump appears smooth but actually pulsates rapidly. The pump may be noisy if mounted on a light unsupported surface - particularly if metallic pipework is used. This pump was retrofitted by the previous boat owner as a replacement for a Jabsco diaphragm pump pressure accumulator arrangement.
The accumulator is still in the line. The issue is when a faucet is opened the VFLO pump kicks on at 30 psi as the water demand slows and then stops the pressure builds in the system the VFLO gradually slows.

The greater the distance a pump has to pull the water the lower the flow rate will be. Get too far from the water source and the more power is dedicated to sucking the water and less to discharging reducing the flow rate. Typically pumps should be with 20 feet of the water source.
Depending on the typography how high the pump is. The Whale Water System is a user-friendly system for the do-it-yourself boat ownerOn-demand pumps have a pressure switch that makes the pump build up pressure in the fresh water line. In this case sufficient raw-water may be able to exit through the open elbow to keep enough raw-water flowing through the engine heat exchanger.
Could be the wire is shorted somewhere between the breaker and the pump. Or the pump could have an issue. Does the pump seem to be working properly.
If the pump is stalled for some reason like a clog the breaker could go. If you have a multimeter check for continuity between the positive after the breaker and ground. Thermostat not functioning properly.
Check to make sure that the thermostat is of the right type. Check to make sure that the thermostat is properly installed. Make sure thermostat functions properly.
Lack of raw-water flow. Restrictions on the inlet side of the raw-water pump. I have a 2000 21 vlx with a 325 indmar in it.
The raw water pump needs replaceing and I have tried to get it off. The pump base is stuck to the pulley that sits between it and the harmonic balancer. I took off the belt thinking that I could take pulley and all off but it only moves about a 116.
The easiest way to do this would be to fill up a bucket with water and test the water pump from that. You would do this by taking the pipe off of the water tank and placing it in the bucket of water. If the water pump is working fine the problem probably lies with the tap on the water tank.
To check if your water pump itself is working you could connect the 2 wires that are connected to the switch with each other so that you close the electrical circuit. The pump should run now. If not the water pump might be defect.
Check out the above video for an RV water pump troubleshooting noise-fixing remedy. Locate the water pump and turn it off. It may be under the bed under the sink or under the rig.
Step 2 Turn off the pump. Step 3 Remove the pump by unscrewing it and put a piece of felt or rubber padding under the pump. A manual marine head.
