A shower arm snapped off the pipe, and a customer in the Kings neighborhood of Londonderry called O'Loughlin Plumbing & Heating. Ryan and Aiden were flexible with scheduling, gave reasonable pricing on a couple of faucets that needed replacement, and found a severely corroded fixture under the sink. The work runs from small fixes to whole systems. A customer who had recently bought a property had Ryan inspect two toilets and replace the wax rings on both, one of which was wet; he also corrected a leveling issue with shims, re-caulked the base and replaced old shut-off valves. A customer said they set up a new indoor drain for the AC, because the old one went through the sill wall and was hanging exposed outside. The business holds 5 stars from 26 Google ratings. A 2026 customer said O'Loughlin handled the plumbing for a full home addition, including a new bathroom, basement plumbing, sewer line work and venting through the roof, and that everything passed inspection. A 2026 customer said Ryan came by on a Sunday for a boiler problem and had them up and running in no time. A 2025 customer said Aiden helped troubleshoot a boiler that was running constantly and bypassing the thermostat, remotely from pictures, until the customer could disconnect what was causing the problem. A 2025 customer in her 80s said Ryan was in her kitchen in a few hours and installed the water heater the next day. A 2025 customer wrote that Ryan's son Aiden had joined as a new business partner.
