Toilet Repair Milnerton | Running & Faulty Toilet Fix

About Toilet Repair (Running / Not Flushing) in Milnerton

A running toilet is more than just an annoyance - it wastes a staggering amount of water. A toilet that runs continuously can waste over 200 litres per day, pushing your municipal water bill up significantly. In South Africa, where water tariffs increase steeply in higher consumption bands, a running toilet can cost you hundreds of rands per month in wasted water alone.

The most common causes of a running toilet are a worn flapper valve that no longer seals the flush valve opening, a faulty fill valve that does not shut off when the cistern is full, an incorrectly adjusted float mechanism, or a cracked overflow tube. Less commonly, the flush valve seat itself becomes corroded or pitted, preventing a proper seal even with a new flapper.

At Abacas Solution, we carry replacement parts for the most common toilet mechanisms used in South African homes, including Wirquin, Fluidmaster, and locally manufactured components. In most cases, we can repair your toilet in a single visit without needing to order parts. We also handle toilets that flush weakly, flush intermittently on their own (phantom flushing), or make constant hissing or dripping sounds. Our plumbers in Milnerton diagnose the specific fault, explain what needs to be replaced and why, then complete the repair and test thoroughly before leaving.

This is one of several specialist services we offer under toilet repairs & installation in Milnerton. As part of our Milnerton plumbing team, we bring over 25 years of hands-on experience to every job.

When to Call for Toilet Repair (Running / Not Flushing)

Our Toilet Repair (Running / Not Flushing) Process

1

Describe the Problem

Call 067 071 9472 or WhatsApp us. Tell us what the toilet is doing - running constantly, flushing weakly, making noise, or not flushing at all. This helps us bring the right parts.

2

Diagnosis

We inspect the cistern internals, identifying which component has failed. We check the flapper, fill valve, float, overflow tube, flush button mechanism, and seal between cistern and bowl.

3

Repair & Replace

We replace the faulty component with a quality replacement part. If multiple parts are worn, we recommend replacing the full internal mechanism to avoid a return visit in a few months.

4

Test & Adjust

We test the flush cycle multiple times, adjust the water level to the correct mark, check for leaks at all connections, and confirm the toilet fills and stops correctly every time.

Many homeowners in Milnerton who need toilet repair (running / not flushing) also require blocked toilet in Milnerton and toilet installation & replacement. We handle everything, so you only need one call.

Safety & Compliance

A continuously running toilet can overflow if the overflow tube is cracked or too short. Check your cistern periodically for signs of constant water movement. In areas with load shedding, note that some properties with pressure-boosted water systems may experience pressure surges when power returns, which can damage toilet fill valves. Consider installing a pressure reducing valve if you experience repeated fill valve failures.

Toilet Repair (Running / Not Flushing) Cost in Milnerton

A straightforward toilet repair such as replacing a flapper or fill valve costs R350-R600 including the part. Replacing the complete internal cistern mechanism (fill valve, flush valve, flapper, and float) typically costs R500-R900. If the toilet requires a new flush button assembly or the seal between cistern and bowl needs replacing, expect R400-R750. Older or imported toilets may require special-order parts at additional cost.

Frequently Asked Questions

Why does my toilet keep running in Milnerton?

The most common cause is a worn flapper valve - the rubber seal at the bottom of the cistern that lifts when you flush. Over time, the rubber deteriorates, warps, or accumulates mineral deposits, preventing a proper seal. Water then trickles constantly from the cistern into the bowl. Less commonly, the fill valve fails to shut off, or the float is set too high, causing water to flow into the overflow tube.

How much water does a running toilet waste?

A running toilet can waste between 100 and 500 litres per day depending on the severity. In South African municipalities where water tariffs are tiered, this extra consumption pushes you into higher billing bands. A moderately running toilet can add R200-R500 per month to your water bill. Fixing it promptly pays for itself within the first billing cycle.

Can you fix any toilet brand?

We repair all toilet brands commonly found in South African homes including Lecico, Vaal Sanitaryware, Duravit, Grohe, Geberit, Kohler, and imported European and Chinese units. We stock parts for the most common mechanisms and can source specialist parts for less common models within 1-2 working days.

Should I repair or replace my old toilet?

If the toilet is less than 15 years old and the bowl and cistern are not cracked, a repair is almost always more cost-effective. We can replace all internal mechanisms for a fraction of the cost of a new toilet. However, if the porcelain is cracked, the toilet wobbles on the floor due to a corroded flange, or it uses more than 9 litres per flush, replacing with a modern dual-flush unit will save water and money long-term.
