... then be sure to check the anode in your tank more often.  I'd check it when you add softening and again in six months to see how fast the anode is being used up.

things to check

@ November 23, 2013 8:08 PM in Vaughn Water Heater

Hello:  Yes, your heater is old, but if it's set up now so a leak won't cause damage to floors, walls or stuff, then keep the unit going.  I'd have a look at the elements, thermostats, dip tube and relief valve.  Your problem of reduced hot water are most likely a damaged dip tube or burned out lower element. 

Do check or replace the relief valve.  A heater blowing up will just ruin your day.

... are caused by the water supplier, then they are likely having a pumping problem and need to know about it.  I had a problem where the house pressure fell to less than zero every 55 minutes, but only for a second.  The nearby pumping station controls were messed up and the water utility didn't know.  A recording pressure gauge might be useful.

Shower heat exchangers...

@ October 18, 2013 9:26 PM in saving $$

... used to be vertical, so there was limited application.  Now there is a horizontal unit called Eco Drain  http://www.ecodrain.ca/  They will be giving a talk at the ACEEE Hot Water Forum coming up in Atalnta GA.  Double wall just is, but units can still reclaim 60% of the otherwise lost heat.

... http://en.wikipedia.org/wiki/Budd_Company  it looks like Budd Company is unlikely to be able to help you.  I'd look at the element itself and contact someone like Chromalox http://www.chromalox.com/ to see if they make something that will work. Good chance they made the element in the first place.

Fair Warning

@ October 17, 2013 12:34 AM in I'm finishing up the seminar part of our business.

Thanks for the warning Dan.  I can only guess how much work it is to put on seminars. 

So, here's an idea.  Why not film the ones coming up and get them on DVD or download so we all can continue to learn?  A good film guy and some editing can go a long way! 

Now we just need a title.... "The Virtual Dan Series"   :~)

Yours,  Larry
ps.  Hope you're headed West for a seminar or two.

questions

@ October 11, 2013 11:51 PM in Standard Hot Water Tank

Hello:  Questions that come to mind:
1. Do you take tub baths?  If so, you'll want a bigger tank.
2.  Would the tank live in conditioned space?  If so, thicker insulation may not be much benefit.
3.  Do you have space cooling?  Thicker insulation on tank is then good!
4.  More anode in tank means you need to service it less often. T&P should still be checked yearly.  Does that servicing frequency matter to you?
Other things:  I prefer magnesium anodes over aluminum, mostly for health reasons.  All tanks have overheating protection, called a high limit.  Shop brand based on how well it's represented nearby.  Good warranty service or access to parts is important when the tank goes cold Friday afternoon.  Plastic drains are common and easily replaceable.

@ September 23, 2013 11:07 PM in 2 Gallon electric water heater.

... has an anode in it, there will be gas formed and there doesn't seem to be a way for it to escape.  I'd agree with venting at a point where the gas collects.... unless the "quadrature gravity" is at work. :~o

Yours,  Larry

A suggestion slightly off topic...

@ September 22, 2013 2:12 PM in bury pex heating lines?

...is that you put your well-insulated water lines in conduit.  Earth is essentially always wet and is a wonderful heat sink!  The moisture, even with insulated lines, will carry off loads of heat.  If you keep the lines in conduit, you'll prevent that loss and be able to get to the lines if needed.   Others will have to comment on depth of burial and frost line, though if the water flow stops, it must become the same temperature as the surrounding soil in a few hours or less.

... put what you saw wrong in writing and give it to the homeowner.  Seems to me you're not doing him any favors by not telling him.  Just stick to the facts.  It's up to him if or how to respond, but at least he'll know there is a problem.

@ July 3, 2013 1:39 AM in corrosion on hot water tank inlet

... a lot looks wrong here.  With melted insulation, drafting is a problem.  It is either negative air pressure in the building, pulling heater fumes back, or a partly blocked flue.  In either case the poorly sloped vent makes it worse. ~~ I didn't like the look of the vent pipe to draft hood connection.  The vent should not be crimped and should go over the draft hood. ~~ I'd rather see lined steel nipples or brass used in the tank, then to flex connectors, rather than copper pipe directly to the heater. This would help prevent galvanic corrosion. ~~ The water might be condensation or it could be a leak.  You might want to uncover the pipes and mop up any water to see if you can find where it comes from.

Yours,  Larry

@ June 30, 2013 11:57 AM in asphalt laminated kraft paper and staple up radiant floor heat

... you can hook up an electric water heater to the tubing in a room and heat it up?  That would give you an answer pretty fast.

cross connection

@ June 16, 2013 2:06 AM in Plumbing Forum?

Hello:  It sounds like water is leaking from hot to the cold side of the plumbing, but testing for it will give you some more info to work with and help in the fixing of it. 

To test for cross connection, turn off water to your water heater.  If it's electric, turn off power, if gas turn to pilot.  Open a hot tap somewhere other than the shower and see what it does.  If there is no cross connection, the water will run only a little, then stop.  Otherwise it'll keep running.  If it runs, go back to the shower and listen for a high pitched ssissing sound.  Let it run a few minutes.  Stop the test , put things back as they were and then run hot water at the shower.  If the valve is cold and runs cold for a while first, you know that cold water came from testing and that there is a cross connection at the shower valve.

From there it's valve seats and/or washers/seals that are leaking.

Yours,  Larry

ps.  100 psi is too much.  40-60 is considered normal and is easier on the plumbing.
