Toilet Costing You Some Money?

How outdated is your toilet? If your toilet was manufactured before 1994, it is quite likely costing you a lots of money in water. Most older toilets used 3.5 gallons every flush (gpf). Modern low-flow toilets draw on only 1.6 gallons every flush and the most up-to-date low-flow types deliver the equivalent volume of flushing power as old 3.5 gallon models. A Preferred Plumbing & Drain plumber can install an cost-efficient new toilet that will cut back on water and save you dollars month after month.

Now there are many innovative eco-advantageous toilet designs that go even further to conserve water. A few types have a dual flushing technique that makes use of no more than 0.9 gallons to flush the liquid waste but all 1.6 gallons to flush solid waste.

Running Toilets

If you hear water running in your trusty toilet tank for lengthy durations following a flush, then your toilet is leaking. It is dumping water down the overflow tube and using as many as 200 gallons of water every day. The main problem may very well be a corroded overflow pipe or flush valve assembly. Often times the offender is a fatigued flapper valve. Give up jiggling the handle and call Preferred Plumbing & Drain. Chances are you’ll help save more than enough cash on your next few water bills to take care of the rate of the plumbing repair.


Could there be a more helpless experience than when a toilet will not flush? Water springs up from the bowl and starts spilling on to the ground as strain takes hold. If a toilet calls for plunging on a routine basis, there is probably a blockage in the trap or further down the drainpipe. It might possibly even be a symptom of a even bigger problem even farther down the sewer line. We’re specialists at dealing with clogged toilets.

Showers and Tubs

Modern bathrooms showcase a variety of shower and tub ideas. Almost all are traditional tub & shower combinations, others are opulent with a diversity of water jets, shower heads and faucet patterns. Preferred Plumbing & Drain licensed plumbing experts are masters of all shower repairs, bathtub drain repairs, water pressure problems and even installations/replacements. We are the experts to call for your bathroom plumbing answers.


How to switch off the water supply if your faucet cracks? It occurs. Faucets break, from time to time violently, and water can start spewing all over the walls and flooring. Don’t panic! Look below the sink for the water shut-off valves. There is usually a cold water shut-off valve as well as a hot water shut-off valve. They’re usually chrome with a small oval valve handle. Turn the handles clockwise till the water stops flowing out of the faucet. Now and again water shut-off valves stiffen from lack of use. If it will not shift, grab a pair of pliers and bit by bit turn the knob forward and backward up to the point the rubber seat on the inside loosens. Don’t force it all at one time or it could quite possibly break and trigger greater plumbing trouble. If the valve spins without restraint and won’t turn the inner seat, tighten the set screw on the face and make an attempt again. After the valve is turning, turn off the water and contact Preferred Plumbing & Drain.
