Before adding water to a hired portable toilet, check the handover instructions or contact the supplier. Different tanks and fittings have different jobs. Opening the wrong point can contaminate the unit or damage it.

What should I check first?

Identify the unit and describe what has stopped working: the flush, the hand basin or both. Check whether the toilet is otherwise usable and whether there is any leak. Give us the site address and a photo of the relevant fitting if you are unsure.

Do not remove waste-tank covers, pour water into an unidentified opening or assume a marked capacity from another model applies to yours.

Does a hired toilet arrive with water?

Our units are supplied prepared for the agreed hire. Standard construction visits include fresh water replenishment as part of the fortnightly service. Usage can require attention sooner, so contact us if water runs low between visits.

Short-term event and trailer hires do not include ongoing servicing by default. Discuss water and waste arrangements before a long booking, particularly at a remote campsite where access may be difficult.

If the supplier confirms you can refill it

Follow the specific unit instructions and use the identified clean-water filling point. Use suitable clean equipment, keep it away from waste fittings and avoid overfilling. Do not add cleaners or other chemicals unless instructed for that tank.

A refill does not empty the waste tank. If the toilet is not flushing because of a blockage, rising waste or a fault, adding water may make the problem worse. Stop using it and contact us for the next step.

Can I connect it to a garden hose permanently?

Do not modify the supplied unit or improvise a permanent connection. A sewer-connect toilet is a different arrangement with water and sewer connections handled by your plumber.

For regular checks during hire, read keeping portaloos hygienic. For a fault involving leaking waste, use the overflow guidance.

Frequently asked questions

Can I refill a hired portaloo myself?
Check the unit instructions or ask us first. Use only the identified clean-water filling point and suitable clean equipment if refilling is confirmed for your unit.
Will adding water fix a toilet that will not flush?
Not necessarily. Low water, a blockage, rising waste or a fault can cause problems. Do not keep adding water to a leaking or backed-up unit; contact the supplier.
