- Tools you need are cup and towels for bailing, screwdriver, wet/dry vac (helpful).

Tools
- Cup and towels for bailing
- Screwdriver
- Wet/dry vac (helpful)
Parts
- None for most fixes. Drain pump if the whole path checks clear
Step by step
-
1 Bail the standing water
Cup, towels, or wet vac the pool so you can see the tub floor.
-
2 Clean the filter and sump
Twist out the filter (see the filter guide) and check the sump beneath for the usual suspects. Glass, labels, a pistachio shell perfectly sized to block the drain port.
-
3 Check where the hose ends
Under the sink. Is the drain hose kinked? If it connects to a garbage disposal installed in the last year, verify the knockout plug was punched out, the #1 "new disposal" mystery.
-
4 Clear the air gap if you have one
The chrome cylinder by the faucet. Pop its cap and clean out the debris. A clogged air gap backs the whole system up.
-
5 Run a rinse cycle and listen
A healthy drain pump makes a steady hum with gurgling water. Silence or grinding with a clear path = the drain pump itself, cheap part, moderate access.
