How much water can the Willy Vac pump?
The actual pump is rated at 2400 GPH, but due to restrictions the Willy Vac moves around 1000 GPH.
What is it made of?
Plastic! With the exception of the diverter valve (which is made of brass) and the parts inside the vacuum motor and pump, everything is plastic or rubber.
What if the unit goes under water?
The pump assembly can be completely submerged and still work fine.
How much room does the unit take up?
The vacuum motor was separated from the sump assembly to allow the unit to be installed in small areas.

Where do I install the sump assembly?
You should install it as low as possible, but wherever it fits your boat the best. Keep in mind the lower it is, the faster it will move water.
Can the unit be plumbed throughout all the bilges?
Yes, the relay box is pre wired to accept a total of three remote switches that can be mounted anytime and easily wired.
Who can install the Willy Vac?
Although any boat yard would be able to install the Willy Vac for you, the Willy Vac was developed so that a captain or owner-operator with moderate plumbing and electrical skills can order and safely install it himself.
What is the warranty?
The vacuum motor carries a 90 day warranty against manufacturer defects. Unused equipment can be return within 15 days. 
What if it breaks?

If you encounter a problem, please contact Tech Support and we will help you through any problem that arises.
Can the unit separate oil?
Currently the filtering assemblies are being developed and are not in production. However, we offer for purchase an attachment for the end of the vacuum hose. The attachment holds a bilge diaper that is used to catch small amounts of oil and prevent it from entering the sump assembly.
