Is it necessary to winterize outside faucets before cold weather hits?
Yes. Taking the necessary steps by turning off the water to these sources disconnecting and storing your hoses and draining water will prevent possible freezing and breakage.

There’s a whistling sound that seems to come from my plumbing. What could cause this noise?
A whistling noise is usually a toilet’s fill valve that is leaking. This is a much easier fix than you may have thought when first hearing the noise.
I need to replace a toilet that doesn’t flush properly. What do you recommend to fix this problem?
The government mandated that new toilets use no more than 1.6 gallons per flush. When manufacturers first began putting units out on the markets with these standards, the toilets did not flush as effectively as the old models. If this is a problem, one solution may be to try a toilet that has a pressurized tank. These work similar to a commercial toilet but are kept to the regular government standards.
