68.0. "Heat - Temp/pressure valve venting" by MPGS::FORAN () Fri Dec 13 1991 15:33

    	In have a 6 yr old Sears gas hot water heater, the temp/pressure
    valve has vented twice in the last two days, what causes this (dont
    come back & tell me temp or pressure!)  What has or is happening inside
    my water heater to cause this??  is it plugged up due to sediment?? I
    have never drained it.

68.1probably the TP valve itselfAKOCOA::CWALTERSFri Dec 13 1991 18:3714
    
    
    Sediment is more likely to *reduce* temperature and pressure, but
    furring of the hot-out pipe might be the cause.   However, It's probably
    the vent valve-spring has weakened.  If you can live with it, try
    reducing the cold water pressure at the inlet valve (or at the mains)
    and see if the valve stops blowing.  If that does it then replace the
    valve - all you need is a wrench, a new valve and a bit of thread sealing
    compound or tape. 10 minute job.

68.2 Pin-hole rusted inMPGS::FORANMon Dec 16 1991 15:176
    	Thanx, Collin, it turns out upon closer examination that there was
    a pin-hole just below the T&P valve so I had to replace the heater
    anyhow!!  The good news is that I got a free replaement heater from Sears

68.4Yup, I'm happy.MPGS::FORANWed Dec 18 1991 13:015
    	Yes, I'm quite happy, even if I did have to pick it up and install
    it myself.   Of course they will not warrantee the replacement for
    another 8 yrs.  My warrantee date is 8/93 the end date of the old
    heater.   But I'm still happy.
    
68.5only time will tell...$$ELWOOD::DYMONThu Dec 19 1991 09:0517
    
    "will not warrantee the replacement for another 8 yrs"
    
    I would call the main office and blow some steam.  Its a new
    tank.  What would have happened it there were 2 days left on
    you old tank warrantee.  "Oh, there is only a 2 day warrantee
    on this tank......."   If all else, it might be worth it to buy
    a service (warrantee) contract seeing your other tank lasted only
    5 years......
    
    Sears can be strange.  For example I went to one place to exchange
    my bad "life time shock" for a new set.   Well, seeing I didnt buy it
    in Springfield and they had changed to a different style shock.  He
    wanted me to pay the difference in price.  I stopped in the Auburn
    store....."Thanks you, Come again!"

68.6QUARK::LIONELFree advice is worth every centThu Dec 19 1991 11:486
This is absolutely normal practice.  The 8-year warranty was included in the
purchase price - they guarantee that you will have a functioning heater for
8 years.  If you want to pay for a new heater, they'll be happy to give you
another 8 years for it.

68.7Check your main pressure regulator, too...MAY21::PSMITHPeter H. Smith,MLO5-5/E71,223-4663,ESBThu Dec 19 1991 15:0814
    I rented in Fitchburg for a while.  The hot water heater would vent onto
    the floor every night, around 3:00am.  At first we thought it was a weak
    pressure valve, but three valves later could not believe that was the
    problem.

    Turned out that there was a problem with pressure regulation (no pressure
    regulator).  When the pressure built up in the morning, the hot water
    tank popped its valve.  This may also explain why we blew a tank while
    we were living there (before the pressure valve problems started with the
    new tank).

    You might just want to check your water pressure, to be sure the problems
    with the hot water tank are not really problems with your pressure
    regulator...
68.8how does it know it's a replacement?TFH::DONNELLYTake my advice- Don't listen to meMon Dec 23 1991 11:396
re: warranty on replacement units.

what i want to know is how come the UN-warrantied replacement unit always 
fails after a year or two.  this has happened to me twice.  the worst case 
was a sears replacement with an 8 year warranty (invalid because it was 
replacement) that failed at 2 years.  -craig
