Pipe it up similar to those in the UK. Elevate the tank on the wall behind the toilet and pipe to the bowl inlet. You will gain pressure by virtue of elevation. And maybe even become a hero. You could replace the flush lever with a fancy chain. Use chrome plated piping between the tank and bowl.
Clean the Bowl and Jets: Use a toilet-safe cleaner to remove buildup and keep the bowl and rim jets clean. Monitor Water Pressure: Low water pressure can affect flushing performance. Contact a plumber if you notice a consistent issue.
The easiest way to fix a slow draining toilet is to unplug the tank and take it off, then clean out the pipe. If this does not work, you may need to replace the flush valve in your toilet. You will want to turn off your water supply before you begin.
There is only one Drano® product recommended for use in slow-running toilets: Drano® Max Build-Up Remover. It contains microorganisms that break down organic matter in pipes that can slow water flow. (However, it will not open a completely clogged toilet. For that problem, see How to Unclog a Toilet.)
Tank Has Too Little Water
If so, the fix is as simple as twisting the flush valve back on. Another reason the toilet won't flush, even if it's not clogged, is that your float ball isn't adjusting to the water levels in your toilet. To fix this, you might need an expert.
After we flush, the toilet water tank requires a lot of water to refill. The water comes from the cold water supply. So when someone flushes, the pressure-balance valve senses a drop in cold water pressure. To counteract this, the valve restricts the release of hot water, resulting in a pressure drop.
Heat 1 to 1 ½ cups of white vinegar to about the same temperature you'd take your coffee – not scalding, but warm enough. Add it to the overflow tube and give it about 30 minutes to work. Flush, then go to work on the jet holes, chipping away the scale with something small but solid.
Place the plunger over the drain hole at the bottom of the toilet, ensuring there's a tight seal that makes it more difficult to lift the plunger. Now, it's time to start plunging. To do this, push down gently into the toilet bowl to avoid splashing, then pull up more forcefully. Repeat this motion 10-15 times.
Can I Install Flushmate® in my existing toilet? No! FLUSHMATE cannot be retrofitted to an existing gravity bowl. Bowls designed to work with FLUSHMATE harness the energy FLUSHMATE delivers to the bowl to create a "pushing" action for the waste.
Clear Flush Holes
These small holes push water from the tank down the sides of the toilet bowl to make sure all waste water flushes down the drain. Over time, the siphon jets will inevitably become blocked with mineral deposits. Clearing up the mineral deposits can provide more water pressure.
If you push down the handle and feel no resistance, the lift chain inside the tank, which connects to the flapper and releases water, has probably shifted, resulting in too much slack on the chain.
Clear any blockages with a wire hanger or vinegar. Ensure the tank's water level is high enough to provide adequate flushing pressure. If your toilet has an adjustable flush valve, experiment with the settings to increase the flush strength. Replace the flapper valve if it's old or damaged.
Adjusting a ball float: The process does not require turning off the water valve or draining the tank. You can elevate the ball float by turning the screw above the fill valve. Raising the float should raise the water level and hopefully solve your water pressure problem.
Check the water level:
This cause by far the most common reason for slow flushing toilets. If the water in the tank is not up to the recommended level, you may have poor flushing power.
The vinegar dissolves the calcium (hard water build up) in the flush ring and the siphon jet, allowing the toilet to once again work as designed. Annual treatment could be necessary. Depending on the amount of hard water build up, repeated applications may be required.
Throw a Bucket of Water into the Toilet Bowl
One of the simplest ways to manually flush your toilet is pouring a bucket of water into the toilet bowl. You'll just need a bucket containing a gallon or two of water. Older toilets may need 3-5 gallons of water to start the flushing cycle.
No, most toilet clogs do not clear on their own. Some water-soluble materials slowly dissolve over time. However, the other materials can fill those gaps. It is very rare for a clog to clear itself.
