Pool plumbing is the network of pipes that moves water between your pool, the equipment pad, and your home’s water supply. When one of those lines cracks, clogs, or loosens, the symptoms often show up as a pool that keeps losing water, wet ground in the yard, or a spike in your water bill.
This guide covers the plumbing side of pool problems — the buried lines, drain lines, and supply connections. For pump, filter, or heater equipment faults, your pool service company is the right call.
Signs of a pool plumbing leak
- ▸Water level drops faster than normal evaporation, even with the cover on
- ▸Soggy or sunken ground along the pipe run between the pool and equipment pad
- ▸A higher water bill with no change in household use
- ▸Air bubbles in the pump basket or return jets
- ▸Pool auto-fill running constantly
Why pool lines fail in the Inland Empire
Shifting clay soil, tree roots, age, and original installation shortcuts all stress buried PVC. Over time, joints crack or pull apart. Water-supply lines to auto-fill and pool-area hose bibs can also leak underground, just like any other water line.
See our leak detection service →How we find the leak
We use non-invasive leak detection to locate the leak before any digging, so the repair is targeted instead of tearing up your whole yard. Drain lines that back up can be camera-inspected and cleared.

When to call a plumber vs. a pool company
Call a plumber for buried pipes, water supply lines, drain lines, and anything that involves water or gas piping. Call a pool service company for pumps, filters, chemistry, and liners. If you are not sure which, call us — we will tell you honestly.
Frequently Asked Questions
How do I know if my pool is leaking or just evaporating?
A simple bucket test helps: fill a bucket to the pool’s water level, mark both levels, and compare after 24 hours. If the pool drops noticeably more than the bucket, you likely have a leak.
Do you repair underground pool plumbing lines?
We locate and repair leaking or damaged buried water and drain lines. Call (949) 379-0082 and we will confirm whether your issue is a plumbing-line problem we can handle.
Do you service pool heaters and pumps?
We focus on the plumbing — pipes, supply, and drain lines. Pump, filter, and heater equipment faults are best handled by a pool service company.
