Water Heater in Nepean, Ontario,

Water Heater in Nepean, Ontario

The old tank had lived a full life. A gas utilization pressure test tag on the outgoing unit told the whole story, dated and filled out by hand. A small paper record of a system that had finally run its course. Time for something new.

We replaced it with a 50-gallon Bradford White power vent natural gas water heater. That is a solid, reliable unit well suited to a busy household. Fifty gallons gives a family real breathing room. No one scrambling for hot water at the end of a line of morning showers.

Along with the new tank, we upgraded the venting to match the power vent setup and installed a dedicated shut-off valve on the hot water tank. That valve matters more than people realize. If something ever needs attention down the road, you can isolate the tank quickly without shutting off water to the whole house.

The new unit runs on natural gas, 40,000 BTU input, built to current ANSI and CSA standards. Everything was pressure tested and signed off properly before we left.

This home is right here in Nepean, and it is the kind of straightforward, thorough job we enjoy doing. The homeowner knew us already, which always means a lot.

If your water heater is getting up in years or just not keeping up, give us a call at 613-518-6114.

Power Vent Water Heater Reinstallation in Nepean, Ontario,

Power Vent Water Heater Reinstallation in Nepean, Ontario

A home in Nepean needed its power vent water heater put back in service. The unit had been pulled out, and until it was properly reinstalled, there was no hot water moving through the house. That is not a comfortable situation, especially when the fix is straightforward with the right hands on it.

We got the power vent unit back into position and reconnected everything cleanly. Power vent systems move exhaust through a dedicated vent pipe using a built-in fan, so the venting has to be set up correctly. We made sure it was. Supply and return lines tied in properly, the unit sitting solid, and everything tested before we left.

No shortcuts on a job like this. Good connections, correct venting, and a unit that is ready to run reliably for years. Power vent water heaters are a solid choice for homes in Nepean where a traditional flue is not practical. They are efficient, they work well, and when they are installed right, they just keep going.

If your water heater needs to be reinstalled, replaced, or looked at by someone who knows what they are doing, give us a call at 613-518-6114. Happy to help.

Drain Cleaning in Arlington Woods, Nepean,

Drain Cleaning in Arlington Woods, Nepean

The drain cover was already off when we arrived, sitting on the tile beside a snake cable and a badly blocked floor drain that wasn't moving anything. You can see it clearly in the before photo. The opening was packed with buildup, dark and completely sealed off. A family in Arlington Woods needed this sorted fast, and we were there same day.

We ran a snake and chain snake through the line to break apart and pull out whatever had been collecting inside that 3 to 4 inch drain. Floor drains in laundry areas take a lot of abuse over the years. Lint, sediment, soap residue. It adds up quietly until one day nothing drains at all.

The after photo tells the story. That same drain opening is now clear, wide open, and ready to do its job again. No standing water. No backup waiting to happen.

It was a straightforward job, but an urgent one. A blocked floor drain can back up fast if a washing machine is still running or a water heater decides to act up nearby. Getting it cleared right away was the right call.

If you have a floor drain that's sluggish or stopped completely, we're happy to take a look. Reach us at 613-518-6114 and we'll get someone out to you.

Drain Cleaning in Nepean, Ontario,

Drain Cleaning in Nepean, Ontario

The kitchen sink at this Nepean home had stopped draining entirely. Completely blocked. The homeowner had already tried the usual fixes without any luck, so they called us in to sort it out properly.

The sink itself is a big stainless steel farmhouse-style basin, the kind that sees a lot of daily use. You can see in the photo that water is pouring straight from the faucet and draining right down without hesitation. That's after we cleared the blockage from the kitchen drain line. The difference between a sink that won't drain at all and one that handles a full stream of water is pretty satisfying to see.

We snaked the drain to break through the clog and get things moving again. Grease and food buildup are the usual culprits in kitchen lines, and this one was no different. Once the line was clear, we ran the water to confirm everything was draining the way it should.

Kitchen drains take a beating over time. Even with care, buildup happens gradually until one day nothing moves. A proper cleaning gets you back to normal and can buy a lot of time before the next issue.

If your kitchen sink is backing up somewhere in Nepean, we're easy to reach at 613-518-6114.

Sewer Backup in Centrepointe, Nepean,

Sewer Backup in Centrepointe, Nepean

That round cleanout access point surrounded by broken concrete and crushed stone tells the whole story. We had just finished cutting into the floor to install a new backwater valve system for a homeowner here in Centrepointe, and this photo shows the valve housing seated in place, flap visible and ready to do its job.

The family had dealt with sewer backup and wanted real protection going forward. So we went in properly. A main backwater valve was installed along with a storm backwater valve as an add-on, covering both drainage lines. We also set up an alarm system so they get an early warning if anything ever triggers the valve. No guessing, no surprises.

The backwater valve itself works simply. When sewage tries to reverse back into the home, the flap closes automatically and blocks it. The alarm adds another layer, alerting the household before water has any chance to cause damage.

Everything is backed by a two-year comprehensive warranty, so the family knows they are covered if anything needs attention down the road.

Sewer backups can hit hard and fast, especially during heavy rain events. Having this system in place means this Centrepointe home is now built to handle it. Give us a call at 613-518-6114 and we will be happy to help.

Under-Sink Plumbing in Nepean,

Under-Sink Plumbing in Nepean

The cabinet under a Bells Corners kitchen sink was collecting water every time the homeowner ran the tap. The culprit was a leaking p-trap. The black plastic drain assembly was misaligned, with connections that just weren't sealing properly anymore. Water had no business being where it was.

We came out, had a good look at the whole setup, and got to work sorting it out. The p-trap is now properly configured, the fittings are seated and secured, and the drain line runs cleanly down to the wall. Everything sits the way it should.

Jobs like this one are easy to put off. A little drip under the sink, a towel tossed in to deal with it later. But moisture in a cabinet adds up fast, and what starts as a nuisance can turn into a bigger headache. Better to just fix it.

If you've got a leak under your kitchen sink, or anything else going on with your drains or supply lines here in Nepean, give us a call at 613-518-6114.
