n What is the difference between a 250mm and 300mm toilet rough-in?

In order to determine your rough-in dimension, please measure from the center of your toilet bolt holes to your finished wall. Most of our toilets are manufactured to accommodate a 300mm rough-in model toilet. If, however, you find yourself in a situation where you do not have enough space to install your tank onto your bowl because the wall is in the way, the solution is our 250mm rough-in toilet.

n What to do if my toilet leaks water onto the floor?

If your toilet is dripping from the tank to the floor, make sure the supply tube nut (coupling nut) is tightened and that there are no cracks in the supply tube. If the supply tube nut is tight, and there are no cracks in the tube, this type of leaking may indicate a non-visible crack in the water control, and its replacement is recommended. Water laying on top of the bowl may indicate leaking between the tank and bowl, which may require replacement of the gasket. Before replacing the gasket, be sure the tank and bowl are securely connected together by checking to see if you can move the tank back and forth.

n Why water keep running in the toilet?

If your toilet is "running" it may be leaking internally. While a plumbing professional's advice is recommended, if your toilet is leaking internally, you can perform the following test. Flush the toilet allowing the tank to refill. Make sure the water level in the toilet is approximately 1/2" below the top of the overflow tube. Put a pencil line where the water level is - this is your starting point. Shut off your water supply. Disconnect the rubber hose that goes from the water control to the overflow tube. (The use of a rubber hose varies by water control model; there may not be one.). Wait 24 hours - see how far the water leaks to in the tank. After this test, reconnect the rubber hose and turn the water supply back on. If the water level leaks to the seat that the flapper rests on, you may need to replace the flapper. If you feel any nicks on the flapper seat, you may need to replace the flush valve. If the tank empties completely, you may need to replace the flush valve.

n Why the toilet tank is not sitting level?

If the tank moves, remove the tank cover and put a level across the top of the tank. Pull the tank down evenly and try to level it out. Using a screwdriver to hold bolts secure, turn the nut with a wrench 1/4 turn left side, then 1/4 turn right side. Do not turn the screwdriver. Go from side to side until tank is secure on the bowl and level.

n Chlorine pucks or other cleaners can be used in toilet tank?

Do not put cleaning agents such as chlorine pucks or cleaners in your toilet tank, as this may deteriorate the tank components.

n Where can I get repair parts for classo toilets?

Please contact your nearby classo service shop. Please be sure to have model number available when calling.

n Can I use any toilet seat on any toilet?

There are industry standards for toilet seats – all toilets have seat post holes on 5 1/2" centers – all elongated bowls are 18 1/2" from seat posts to front of rim, and all round bowls are 16 1/2". Any manufacturer’s seats will fit any toilet manufacturers bowls if they are standard round or standard elongated. If a manufacturer makes a bowl with different dimensions, then they must provide a special seat – this is known as a proprietary seat.

n How do I know if my toilet seat is round front or elongated?

To determine if your toilet is round front or elongated, measure the distance between the center of the bolt holes(A) (which connect the seat to the bowl) out to the front rim of the toilet(B). If it measures approximately 16 1/2" your toilet is a round front. If it measures approximately 18 1/2", it is an elongated model. You'll need this information when replacing your toilet seat.

n What cleaners do I use to clean my Toilet Seat?

When cleaning your toilet seat, wash it only with mild, soapy water; rinse the seat thoroughly with clear water; and dry with a soft cloth. Avoid detergents, disinfectants, or cleaning products in aerosol cans. NEVER use abrasive scouring powders on your seat. Some bathroom chemicals and cosmetics may damage your seat's finish.

n What is a "Slow Close" toilet seat?

The seat hinges are modified so the seat cover gradually closes without slamming.

n What supports a urinal to the wall?

Each urinal has specific hangers that must be attached to studs located behind the wall. These studs (i.e.2 x 6) must be substantial enough to hold the weight of the fixture.

n Why don't classo’s urinals come with component part strainers?

Urinals are not designed to accommodate refuse, and some of our urinals do not have a sump contour that will accommodate a stainless steel strainer. If there are individuals who are throwing refuse into a urinal, you can purchase a flexible rubber mat strainer at a local janitorial service.

n What is a bidet?

A fixture similar in design to a toilet that is straddled for bathing the genitals and the posterior parts.

n What is the difference between vertical spray and over-the-rim bidet?

The vertical spray comes from the bowl of the bidet, aiming the stream of water upward. An over-the-rim fitting is similar to a faucet spout, where the water would come from a fitting on the bidet
