Plumbing & circulation.

Check a clogged pool suction line, rule out air leaks and basket problems, and know what a safe clearing and verification job needs.

Measure pool flow rate in the right pipe and operating mode. Compare meter readings, pump curve estimates and common shortcuts.

Understand pool autofill types, level settings and overflow. Learn what to monitor so automatic filling does not hide a problem.

Find why a pool autofill keeps running. Compare pool and chamber levels, check actual shutoff, and separate overflow waste from water loss.

Troubleshoot a pool autofill that is not filling. Check supply, level sensing, valve response and the route carrying water into the pool.

Adjust pool autofill water level using the right float or sensor procedure. Set a useful target and verify filling stops below the overflow.

When pool return jets become weak, first establish whether the change affects every outlet or only one branch. Compare them under the same pump program and operating mode. That narrows the investigation before you clean a filter, replace a fitting, or suspect the pump.

Pool plumbing carries water from the pool to the equipment and back again. Start by separating the suction paths before the pump from the return paths after it. That simple map makes valve labels, leaks, and weak circulation much easier to interpret.

A pool skimmer draws surface water into a collection point and catches larger debris before it reaches the equipment. The basket is only one part of that job. The mouth, floating weir, water level, and connected plumbing determine how well debris reaches and enters it.

A pool skimmer not suctioning needs a whole system check before a pipe blockage diagnosis. Compare the return flow, pump basket, operating schedule, and any other skimmer. That tells you whether water movement is weak everywhere or mainly at this branch.

A pool skimmer not collecting debris may still be moving water normally. Watch whether leaves reach the mouth, enter it, and remain in the basket. Those three stages separate a surface current problem from a weir, basket, or flow problem.

One pool skimmer not working does not always mean its pipe is blocked. The two skimmers may receive different amounts of debris or share plumbing that divides flow unevenly. Compare them under the same operating conditions before changing valves or replacing parts.
