Toilet Costing You Money?

How old is your toilet? If your toilet was sold earlier than 1994, it is certainly costing you a bundle of money in water. Most older toilets used 3.5 gallons per flush (gpf). Current low-flow toilets take only 1.6 gallons for each flush and the latest low-flow designs provide you with the same amount of flushing power as old 3.5 gallon models. A Preferred Plumbing & Drain plumber can set up an effective new toilet that will reduce the use of water and save you some money month after month.

There are plenty of brand new eco-advantageous toilet versions that go even further to help you save water. A number of models have a twin flushing method which in turn utilizes only 0.9 gallons to flush the liquid waste but all of the 1.6 gallons to flush solid waste.

Running Toilets

If you hear water running in your toilet tank for extended periods of time after a flush, then your toilet is leaking. It is dumping water in the overflow tube and throwin away almost 200 gallons of water day-to-day. The problem could be a corroded overflow pipe or flush valve assembly. Often times the perpetrator is a shot flapper valve. Avoid jiggling the handle and call Preferred Plumbing & Drain. Odds are you’ll help save enough money on your upcoming handful of water bills to pay for the amount of the plumbing repair.


Can there be a more helpless experience than the second a toilet does not flush? Water springs up in your bowl and starts pouring on the ground as strain sets in. If a toilet requires plunging on a regular basis, there is quite possibly a impediment in the trap or even further down the drainpipe. It might even be a indication of a larger crisis even farther down the sewer line. We’re experts at working with clogged toilets.

Showers and Tubs

The latest bathrooms showcase a selection of shower and tub styles. Almost all are normal tub & shower combinations, other types are lavish with a wide range of water jets, shower heads and faucet styles. Preferred Plumbing & Drain licensed plumbing specialists are masters of all shower repairs, bathtub drain repairs, water pressure concerns and even installations/replacements. We are the industry professionals to call for your bathroom plumbing help.


How to switch off the water supply if your faucet cracks? It happens. Faucets break, occasionally violently, and water can start spraying through out the walls and floor. Don’t stress and panic! Glimpse under the sink for the water shut-off valves. There should be a cold water shut-off valve in addition to a hot water shut-off valve. They’re typically chrome with a compact oval valve handle. Just turn the handles clockwise until eventually the water quits pouring from of the faucet. Occasionally water shut-off valves stiffen from lack of use. If it isn’t going to move, pick up a pair of pliers and bit by bit turn the knob back and forth till the rubber seat inside loosens. You shouldn’t force it all at once or it may bust and produce even larger plumbing conditions. If the valve turns freely and will not turn the internal seat, tighten up the set screw on the face and make an attempt again. The moment the valve is turning, turn off the water and contact Preferred Plumbing & Drain.
