D. The Spraywater is Cold
1. Check to see if the water heating system supplying the unit is on. The temperature of the
hot water at the inlet of the thermostatic mixing valve should be between 130o and 167oF.
The water pressure at the inlet of the thermostatic mixing valve should be such that a minimum
of 17 psi of flowing pressure is obtained at the inlet of the control valve.
2. Check to see if the hot & cold water supply lines are connected to the right inlets of the
thermostatic mixing valve. The thermostatic mixing valve is marked with H for hot water and
C for cold water.

Try sticking your fingers between the drainpan and the
bowl. If you feel a gap, the bowl has been installed
incorrectly. To reinstall the bowl correctly, follow the
next steps.

C. Water Hammer
1. Measure the water pressure at the inlet of the control valve. The Sanispray works properly
between 17 and 100 psi. If the pressure is higher, close the ball valves on the hot and cold
supplies inside the pedestal to the point where there is still a nice waterspray and a minimum
of 17 psi water pressure.
Disconnect the water flexible
supply from manifold and push
inside the column.
Remove the four allen screws
and lift the head from the
pedestal.
A. Insufficient waterspray when activating the valve
1. Check to see if the main supplies are open, the water heating system is on and the stop valves
inside the pedestal are open.
2. If the flow is inconsistent between valves, check the condition of the screen at each valve inlet.
Service when necessary (see page 3- Clean Strainers).
3. Check the water pressure at the inlet of the control valve. The Sanispray requires a minimum of 17 psi when
the washfountain is spraying.
4. Check the strainer screens. If necessary clean or replace them (see page 3 - Clean Strainers).
5. Check to see if sediments are blocking the nozzles (see page 2 - Cleaning the nozzles).
B. Water Hammer
1. Measure the water pressure at the inlet of the control valve. The Sanispray works properly between 17 and
100 psi. If the pressure is higher, close the ball valves on the hot and cold supplies inside the pedestal to the
point where there is still a nice waterspray and a minimum of 17 psi water pressure.
C. The Washfountain Fails to Shut off.
Remove the access cover and
turn off the water supply to
the unit.
