Maintenance & Troubleshooting


The Aquor House Hydrant can be easily cleaned or serviced from the exterior of the home. If PEX tubing is used, add an extra loop of tubing inside the wall during installation. This way, the entire assembly can be pulled out of the wall from the exterior of the home. (see “Connect to Plumbing” page)

Hydrant PEX loop maintenance instructions

With copper piping, the rear valve housing will stay inside the wall. Unscrew the body of the hydrant from the rear housing in a counterclockwise direction, taking care not to drop the internal spring or rod. If your plumbing code requires the rear of the hydrant to be secured against a stud, you will need access to the plumbing for future maintenance (just like a standard sillcock). We recommend installing into exposed areas like basements, or adding access doors if installing behind finished walls.

The hydrant utilizes two internal o-rings that can be replaced if needed: one that closes the rear valve, and a second that seals the outer housing. With normal use, the o-rings have an expected lifespan of 10 years. Actual lifespan may depend on frequency of use, water mineral composition, pressure, temperature, and other factors.

The House Hydrant’s minimalist design allows for simple and straightforward troubleshooting.

Water leaking from main outlet: When you disconnect the Aquor connector, the House Hydrant self-drains from the rear valve to prevent freezing. This is completely normal. If you observe water still leaking from the outlet after 30 seconds, shut your water off and then unscrew the rear valve housing and inspect the inner rod and o-ring seal. Check for any damage to the o-ring or debris that may have gotten stuck in the valve. If the hydrant continues to leak after re-assembly, contact Aquor support.

Water leaking from rear plumbing adapter inlet: Ensure that teflon tape was used when attaching the 1/2″ NPT plumbing adapter into the hydrant. Sometimes, you may need to screw the adapter into the hydrant more firmly. This is intended to be a permanent connection. If you notice leaks or drips from this connection, your plumbing adapter may have been damaged or compromised. Test the hydrant with another plumbing adapter, using plenty of teflon tape. If it continues to leak, contact Aquor support.

Water leaking from rear valve housing: The rear valve housing is the rearward portion of the House Hydrant. It threads onto the main hydrant stem and is sealed with an o-ring. With the water supply turned off, unscrew the rear valve housing and inspect this o-ring for damage. If cross-threaded, the metal housing threads may cut into the o-ring, potentially causing leaks. Teflon tape is not required on this connection, but can be added. If it continues to leak, contact Aquor support.

Water leaking from vacuum breaker (V2 model only): In the event of backflow siphonage, the vacuum breaker assembly is designed to relieve pressure by letting in air. The breaker assembly should not release water. You can unscrew the vacuum breaker cap to inspect for any signs of damage. If you notice the vacuum breaker leaking water, contact Aquor support.
