What this sheet is for
Know the backwater valve works before the sewer backs up, not when it does. Each line dates one opening, cleaning and check of the gate and seal.
Who it is for
Homeowners and landlords with a backwater valve or sewer backflow valve fitted to the drain.
How to use it
- Fill in the valve's location, type and installer once, from the paperwork or the plumber.
- Make sure nobody will run water in the house, then open the access cap as the maker describes.
- Note any debris, how you cleaned it, whether the gate moves freely and the seal's condition.
- Refit the cap and seal it, test the alarm if there is one, and write the line before you forget.
- Call a plumber if the gate still sticks, and record what they did at the foot.
What is on the sheet
One page, top to bottom:
Printed under the title: Every time the backwater valve's access cap comes off: what was inside, how it was cleaned, whether the gate or flap moves freely, the seal, and the cap going back on tight.
The maker's instructions first. No inspection interval is printed: follow the valve maker's instructions and any advice from your drainage utility, and look again after heavy rain or a sewer backup nearby. Make sure nobody runs water in the house while the cap is off, and call a plumber if the gate will not move freely after cleaning.

Questions
How often should a backwater valve be cleaned?
Follow the maker's instructions and any advice from your drainage utility; the sheet prints no interval because valves and local advice differ. A look after heavy rain or a sewer backup in the street is sensible on top of that.
What is the difference between normally open and normally closed?
A normally open valve lets the flow pass and closes when sewage pushes back; a normally closed one stays shut and opens to let the flow out. The type changes what you see when you open it, so write it at the top.
