Leaking P-Trap Repair in Dover
Most puddles under a bathroom sink start at the P-trap. Slip-joint washers flatten over time, plastic traps crack, and old chrome traps rust through from the inside. We replace the trap with a properly sized 1-1/4 inch assembly, align the tailpiece and wall arm, and run water to confirm a dry seal. This is one of the fastest and least expensive fixes we do.
Sink Water Pressure Issues in Dover, DE
Low water pressure at your sink can be annoying and indicate underlying plumbing problems such as mineral buildup in the aerator, faulty faucet cartridges, or even larger issues within your home's water lines. Our technicians in Dover, DE can correctly diagnose the cause of low pressure and make the necessary repairs to restore full water flow to your sink.
Overflow and Drain Body Leak Repair in Dover, DE
Water that appears only when the sink is full often comes from the overflow gasket or the drain flange putty. We pull the drain, clean the old putty or sealant, and reset the flange with fresh plumber's putty or silicone based on the basin material. Then we fill the bowl past the overflow and check for drips. This kind of leak is easy to miss and easy to fix once found.

If your garbage disposal is jammed, humming but not grinding, or leaking, it needs expert attention.

Pop-Up Drain and Stopper Repair in Dover, DE
When the stopper will not close, will not open or lets water slowly escape, the pop-up linkage is usually to blame. The pivot rod nut can leak, the clevis strap can slip, and hair wraps around the stopper body. We clean or replace the assembly and adjust it so the lift rod works smoothly. If the drain body itself is corroded, we replace it with a matching finish.
