16. Do you know low Flush Toilet Problems?

You might buy a better flushing toilet for your situation. Some air assisted toilet flush well. When the low gallonage gravity toilets first came out I replaced a couple of new Kohler Wellworth Lites with the Am.Std. air assist toilet with good results. That was then and this is now. Today most brands of gravity toilets flush well (including the redesigned Kohler Wellworth models). Power assisted toilets tend to be noisy and frankly, today I definitely do not recommend power assisted toilets.
By the end of 1999 (most brands of U.S. made) gravity toilets manufactured were flushing fine. At the end of 2000 my guess is that over 85% of 1.6gpf toilets flushed well.

31. Do you know what is the most common reason for sump pump failure?

The leading cause for sump pump to failure is usually a switching problem. Sometimes the pump can move inside the basin. This movement causes the float that operates the switch to lodge against its side. Debris can also be a factor by interfering with the action of the pump switch. It is important to make sure that your pump switch and float arm assembly move freely. The main thing to remember about sump pumps is that they dont last forevereven if you never use them. Internal part wear out and make them virtually useless when you need them most! Blue Mountain can test, maintain or replace any brand of sump pump. For flood-prone areas and homes that get water seeping in on a regular basis you may want to consider a sump pump back up system. There are even non-electric systems that work in the case of a power failure. Call Blue Mountain for more information.

32. Please explain conventional Water Heaters vs. Tankless Water Heaters?

Conventional water heaters are by far the most common type of water heater in the U.S. today. They range in size from 20 to 80 gallons (or larger) and are fueled by electricity, natural gas, propane, or oil. Called torageunits, these water heaters transfer heat from a burner or coil to water in an insulated tank. The down side to a conventional water heater is that energy is consumed even when no hot water is being used.

Tankless water heaters do not contain a storage tank like conventional water heaters. A gas burner or electric element heats the water only when there is a demand for hot water.

There are many things to consider when choosing conventional vs. tankless water heating systems. Your Blue Mountain representative can guide you through your options and get the right system for home that will give years of service and efficient performance.
