Is Shower Diverter Leakage Normal?
Does your Delta shower diverter drip during use? Learn why small leakage is normal, when it’s a problem, and how to fix diverter issues.
Many homeowners notice some water leaking from the tub spout even after pulling up the shower diverter. With Delta spouts that use a pull-down ring, the leakage is often less than with older diverters. This raises the question: Is a small leak normal or a sign of a bigger problem?
In this case, the Delta diverter does not leak a full pencil-sized stream. Instead, the water dribbles or drips while the shower is running. The concern is whether this is intentional design or if the diverter needs repair.
Question:
Is a small leak from a Delta pull-down ring shower diverter normal, or should it be repaired?
Answer:
Yes, a small leak is normal. Diverters are designed to allow minimal leakage so that pressure does not build up in the system. A slight dribble or drip is acceptable. However, if water runs as a steady pencil-sized stream, the diverter may be worn and should be replaced.
The pull-down ring diverters on Delta faucets are known for being reliable and often last longer than traditional lift-gate diverters. Over time, mineral buildup and worn seals can increase leakage. If the leakage grows stronger, replacing the spout or diverter insert is the best fix.
Regular maintenance can help reduce problems. Flushing the faucet system, cleaning buildup, and checking seals will extend the life of the diverter.
