Simple Tips to Protect Your Plumbing

We recommend a few simple habits to keep your system healthy, starting with regularly checking your water pressure. High pressure can strain your pipes and lead to "pinhole" leaks over time. Additionally, performing annual water heater flushes by draining a few gallons of water can prevent the mineral "crust" that often burns out heating elements in our region. Finally, it is vital to watch what goes down your drains; we strongly suggest avoiding harsh chemical "drain cleaners," which can eat away at the older pipes found in many Ontario homes. Instead, opting for professional hydro-jetting is a much safer way to clear grease and roots without compromising your plumbing's integrity.

    “What an amazing day, who can say that after a water heater breakdown? We called, and you guys didn't let us down. 20 minutes after our call, the service repair men were joyfully, professionally ready at my door. They examined, explored, determined what happened to our 3 year old Water heater, found our house regulator valve shot, corrosion was filling the diaphragm of it, preventing it from regulating our water pressure. Because our water pressure was over 100 psi, our 3-year-old water heater inner liner was torn through, and the entire tank was emptying around the lower seam. Everything was shown, explained, and once they learned that my husband is 100%disabled vet, and currently recovering from shoulder surgery. The discounted price met our ability, and 2 hours later, we have a new water heater and water regulator, and are happy that this company met our needs.”
