FAQs
What is a pressure-assist toilet and how does it differ from a standard gravity toilet?
A pressure-assist toilet has a sealed pressure tank inside the porcelain tank. When the tank fills, water is trapped under air pressure. Flushing releases this pressurized water in a quick burst, pushing waste through the bowl and drain line more forcefully than a gravity toilet, which relies only on the weight of the water. The result is a more powerful, clog-resistant flush that clears the bowl with less water per use.
What advantages will I see by upgrading to a pressure-assist unit in my Soddy-Daisy home?
Homeowners typically notice three main benefits: 1) Superior flushing performance that virtually eliminates double flushes and reduces clogs in older drain lines common in Soddy-Daisy houses; 2) Water efficiency—most pressure-assist models use 1.0–1.4 gallons per flush versus 1.6–3.5 gallons in older gravity toilets, lowering monthly utility bills; 3) Cleaner bowls because the high-velocity water sweep helps keep surfaces free of residue, reducing scrubbing and chemical cleaners.
Will a pressure-assist toilet fit my existing rough-in and plumbing connections?
In most cases, yes. Pressure-assist toilets are manufactured with the same 12-inch rough-in dimension and standard floor flange bolt pattern as conventional toilets. The water supply line uses the same 3⁄8-inch compression fitting. During our on-site evaluation, we verify clearances, shut-off valve condition, and venting to ensure compatibility. If any adjustments are needed—such as replacing an aging angle stop or reseating the flange—our technicians take care of it during installation.
Are pressure-assist toilets noisier than regular toilets?
They are slightly louder because of the rapid release of pressurized water, producing a brief whooshing sound that lasts 1–2 seconds. Modern designs have reduced noise levels with insulated tanks and improved air-water mixing chambers. For most households, the difference is minor and comparable to closing a shower curtain or running a faucet. If sound is a concern, we can recommend low-noise pressure-assist models and add acoustic padding behind the tank.
How much water and money can I expect to save?
Switching from a 3.5-gallon gravity toilet (common in homes built before 1994) to a 1.0-gallon pressure-assist model saves roughly 2.5 gallons per flush. For a family of four averaging 5 flushes per person per day, that’s about 18,250 gallons saved annually. At Soddy-Daisy’s average water/sewer rate of roughly $8.50 per 1,000 gallons, you could save around $155 per year per replaced toilet. The unit typically pays for itself in 2–4 years while conserving a significant amount of water.
