Use a cloth to remove any dirt or oil. Ensure that the surfaces are completely clean by using a mild solvent. Cleaning the surfaces helps the leak guard bond effectively.</li><li style="font-size: 16px;"><strong>Apply the Leak Guard</strong>: Use a small brush or the tip of your finger to apply the leak guard evenly on the mating surfaces. Applying a large amount is not necessary. Use enough to thinly coat the flare&#x2019;s mating surfaces. Create a thin film over the entire surface.<img src="https://attachments.gorgias.help/Q9r0k7BYaV2vg13y/hc/9JWjXVxG8m6DvMqm/2025053014-a6bba8b5-9617-4041-a01f-b92a5155c54a-pioneer_leak_guard_apply.png" style="width: 400px;" class="fr-fic fr-dib"></li><li style="font-size: 16px;"><strong>Connect the Surfaces</strong>: After applying the leak guard, connect the flare fitting properly.</li><li style="font-size: 16px;"><strong>Tighten the Fitting</strong>: Tighten the flare fitting after connecting it. Do not over-tighten the fitting to avoid stripping the threads or cracking the flare.</li><li><span style="font-size: 16px;"><strong>Wipe Off Excess Leak Guard</strong>: Remove any excess leak guard after tightening the fitting. &#xA0;</span></li></ol><p><strong>Note</strong>: Refer to the manufacturer&#x2019;s instructions when working with the leak guard and fittings.</p>

Fix Leaks that are Difficult to Trace

<h2 id="introduction"><u>Introduction</u></h2><p>This article provides solutions for indoor units leaking water.&#xA0;</p><h2 id="solutions"><u>Solutions</u></h2><ul><li>Verify that the indoor unit is both horizontally and vertically leveled.&#xA0;</li><li>Confirm that the drain tube is at a continuous downward pitch.<ul><li>Pour a cup of water over the indoor unit&apos;s coils, so that it reaches the drainpipe.&#xA0;</li><li>Verify that the water drains out of the tube freely.

Solutions for Indoor Units Leaking Water

There are only a few reasons as to why a Pioneer wall-mounted indoor unit could be leaking water.

<p>There are only a few reasons why a wall-mounted indoor unit could be leaking water. The most common reason is the drain tube is cracked, clogged, or not at a continuous downward pitch. The drain tube is an insulated tube on the rear side of the indoor unit.&#xA0;<img src="https://attachments.gorgias.help/Q9r0k7BYaV2vg13y/hc/9JWjXVxG8m6DvMqm/2025053014-578daa63-dd15-4aed-b5e6-8f3bd9ac674e-drain_tube_diagram.png" style="width: 300px;" class="fr-fic fr-dib"></p><p>Check the state of the drain hose, as well as any attached extensions. Conduct a drainage test to ensure that the hose can drain freely. You can conduct a drainage test by opening the front panel, removing any filters, and pouring water over the coils. Check whether the water is properly exiting from the point of drain.<img src="https://attachments.gorgias.help/Q9r0k7BYaV2vg13y/hc/9JWjXVxG8m6DvMqm/2025053014-5ca659f4-d0c1-417f-9ffc-63b2f1254817-drainage_test.png" style="width: 400px;" class="fr-fic fr-dib"></p><p>Another set of possible causes:</p><ul><li style="font-size: 16px;">The indoor unit is not level.&#xA0;</li><li style="font-size: 16px;">The drain pan is cracked or damaged.&#xA0;</li><li style="font-size: 16px;">There is a back-flow of condensate water into the system&apos;s drain pan.&#xA0;</li><li style="font-size: 16px;">The drain outlet port is exposed. Most models have drain ports on both sides, where the unused one stays plugged by a stopper. The Quantum Fresh High-Wall system only has a drain port on the right side of the unit.&#xA0;</li><li style="font-size: 16px;">If the drain pan is filled with debris or dust and preventing water from draining, you can pour a 50/50 mixture of water and white vinegar into the drain pan to unblock it. You can also use specialized cleaner tablets.</li></ul><p>If your system passes the drainage test but drips water from time to time, then your issue is not plumbing/drain related but can likely be attributing to either:</p><ul><li style="font-size: 16px;"><strong>If water drips from the front louver where air blows out:&#xA0;</strong>Make sure the air flaps or louvers are not in a closed position, causing the airflow to be cut. This will lead to a buildup of condensation and dripping. Manipulate the air flaps and louvers to ensure the removal of airflow restrictions.</li><li style="font-size: 16px;"><strong>If water drips as a result of excessive ice/frost forming on the coils:&#xA0;</strong>The system is potentially low on refrigerant. This causes a buildup of icing and frost on the coils to the point where you can see ice completely blocking your view of the coil. This ice then melts and leads to water dripping off of the unit, which is ultimately a symptom of a bigger problem at hand. Check the operating pressure of the system and recharge to spec. if needed.</li></ul><p>On top of all these possible causes, it is always best practice to ensure that your filters, coil, and blower wheel are clean and clear. Otherwise, it can limit the performance of the equipment and potentially lead to unintended consequences, such as water dripping or leakage.</p>
