Might be fun...

@ February 8, 2013 3:46 AM in Cloudy hot water

... to see if you get the cloudy water at the hose bibb on the incoming main line.  If so, installing an air separator could be useful.  It would need to take the line pressure and not be able to rust of course!

Three things

@ January 26, 2013 8:46 PM in Sewer smell mystery...

Thing #1.  Make sure that any closets are true closets and not converted from showers.
Thing #2.  Hope nothing crawled into a wall and died.
Thing #3.  Pour bleach down any  nearby shower drains.  They can make you gag sometimes.

Yours,  Larry

Gas Pressure

@ January 25, 2013 1:12 AM in Rinnai tankless woes

Hmmm:  As gas pressure is so important for tankless heaters, I wonder how difficult it would be to have a "low gas pressure" error code?  It would make life easier for everyone but the installer who didn't pay attention to gas line sizing.

here's a test

@ December 29, 2012 10:49 AM in Electric WH insufficient heat

Hello:  Try this.  Run hot at the shower till it gets as hot as it will. Shut it off and go run hot somewhere else and shut it off.  Now, go back to the shower and run hot.  Does it start out cold?  If so, you know cold filled the hot line and there is a cross connection.  I've met the problem with Moen and Grohe valves.  The polysulfone Moen cartridges replace the brass ones and get rid of the problem... which is nice!

For years...

@ December 28, 2012 12:05 AM in Anode rod

... I measured conductivity between tank and anode that I'd installed with teflon and never found one that didn't conduct.  Went back on many of them years later to find the anode being consumed as it should be.  It seems it should be an issue, but it isn't.

Yours,  Larry

Just to be sure...

@ December 27, 2012 11:58 PM in Electric WH insufficient heat

... check hot water temperature as it leaves the tank to be certain the problem is in the tank.  A cross connection in the plumbing could cause your 106 degree reading.  If it is only 106 leaving the tank, check elements with an ohm meter to see if there is any leakage to ground.

Wierd idea

@ December 18, 2012 1:26 PM in coyote vs road runner application

How about moving the boiler up towards the top of the building, so it runs at the pressure it should?  Piping lower down can take 90 psi without problems. This is a Henry Gifford idea.

...check out the commercial version of demand pumping at: http://www.enovativegroup.com/portfolio/guide-to-the-dmand-circ/  They use a combination of tenant demand and loop temperature to limit operation and reduce losses.  I'd still insulate everything I could get to!

Sounds like crevice corrosion

@ November 26, 2012 11:39 PM in plumber-homeowner-contractor

Have a look here for a description.  http://en.wikipedia.org/wiki/Crevice_corrosion  Fixing it is a whole nuther  problem, though knowing what it is should help in finding an answer.

Congratulations!

Part of advertising...

@ November 19, 2012 11:34 PM in Advertising methods

... seems to be to get your name out there every way possible.  When your prospective client sees it enough (in theory) they become more comfortable with and likely to buy from you.  A single ad on a car or a blimp isn't likely to make someone who has never heard of you buy your product.  When you surround them with your name, you are more likely to get a call when they need your service.

Just imagine the opposite.  Do nothing to get your name out there and see how dusty your phone gets.  Personally, I've found word of mouth is tops for getting good clients.

So, to answer your questions, no, an ad on a car wouldn't make me call.  But, even if a tractor pull is energy inefficient, if your prospective clients like tractors, that's the place to advertise.

50 psi...

@ November 15, 2012 12:54 AM in Hot Water Pressure

... doesn't call for a pressure reducer.  Put a gauge on the tank drain valve and let the tank heat from cold.  If you get up to 80 psi or more, it's time for an expansion tank on the cold side.

Yours,  Larry

Starting at the beginning

@ November 12, 2012 5:27 PM in Hot Water Pressure

What's the cold water pressure?  From there, put your gauge on the drain of the tank and measure static pressure.  It should pretty much match the cold pressure.  Now run hot water.  Does the pressure at the tank fall off significantly?  How about if you open multiple taps?  This will help identify where the restriction is or isn't.  From there it's following on down the hot lines to find out where the pressure drops off.  Do let us know what you find.

Yours,  Larry

thanks Carl

@ November 8, 2012 9:09 PM in What Are the Causes of Water Heater Element Corrosion?

If the elements are failing repeatedly, it might be time to try a different type.  Most heaters come with a less expensive element. that has a copper sheath. They also are usually a "high watt density" style.  This forces more heat through a smaller element surface area, speeding corrosion in acidic or aggressive waters.  Elements also come with a stainless or nickle alloy sheath which holds up better. 

As Carl suggests, do check the anode/s in the heater to make sure "Demon Rust" isn't having a good time in your heater at your expense!

Yours,  Larry

ps.  If the elements you're replacing are covered with scale, understand that chemical reactions in general, double their speed with every 20 degree rise in temperature.  Scale on the element slows heat transfer, speeding up damage to that element.

.... we could assemble a work crew to come and fix your roof!  You know a bunch of talented contractors.  Is it tarped off now?

Have a look at...

@ October 21, 2012 1:58 PM in If you were to build today...

... the thousand home challenge website, http://thousandhomechallenge.com/  Look at the calculator there and see what you need to do to meet the challenge.  It's so much easier with a new house.  From there, a mini-split (can be driven by PV) or some other relatively easy system might be all you need.

Some time soon, you can even read up on my house, which is the 13th in North America to meet the challenge.

@ October 10, 2012 11:36 PM in Clean the "flue" inside the heater?

Hello:  Physically brushing or otherwise cleaning a turboflue sounds challenging with all the welded in projections.  How about getting an  inspection mirror and having a look to see if there is any real buildup of stuff in the flue?  If it's clean, you don't need to worry about it.  If it's filthy; time for the haz-mat suite and power washer!

I'd like to second...

@ October 8, 2012 10:43 AM in Solar water heater electric backup overheat trip

... what Hot Rod said   "A lot depends on the collector to tank capacity ratio, and how much DHW the home uses everyday."  To me, a single 4 by 8 foot collector is undersized for an 80 gallon tank unless you're in someplace hot like Phoenix.  This suggests the owners don't use much hot water.  A non technical fix would be to tarp off about half of the collector in summer.  I'd start though be getting a better idea of how much hot water is really used and how much time is spent away from home.

Yours,  Larry

Anything that promotes...

@ September 23, 2012 12:43 AM in Tank size and shape.....

... stratification in the tank and prevents mixing of hot and cold waters on draw is good.  Usually that means a tall tank with a dip tube delivering water slowly and calmly to the bottom of the tank.  A sixty foot tall heater, four inches in diameter would hold forty gallons, but I've yet to see one.  :~)  That unit would likely deliver nearly all of it's volume as undiluted hot water.... just ignore the standby losses!

... of checking sensors to see how they're doing, is to put both is a glass of water (keep the water level low enough so you don't completely immerse the sensors) and then measure conductivity through both.  They should read the same.   If not, it's new sensor time.  I agree that connections are a problem.  I fill wire nuts with silicon before connecting wires and then aim them up so water cannot collect in the wire nut.  Given the opportunity, mice like to nibble at wires as well.
