00:00:02.330 welcome to DIY easy crafts calm how to 00:00:06.01900:00:06.029 fix a leaking boiler over pressure 00:00:08.57000:00:08.580 relief valve now if your boiler is 00:00:12.04900:00:12.059 dripping water consistently mine was 00:00:15.82900:00:15.839 actually producing about 5 gallons of 00:00:18.01900:00:18.029 water a day 00:00:18.83000:00:18.840 most likely the source is going to be 00:00:21.34900:00:21.359 the overpressure relief valve or the 00:00:24.43900:00:24.449 expansion tank which is usually located 00:00:26.77900:00:26.789 just above it now I actually called a 00:00:30.08000:00:30.090 plumber and to take a look at this and 00:00:31.58000:00:31.590 give me an estimate on repairing the 00:00:33.41000:00:33.420 system and to replace the overpressure 00:00:36.65000:00:36.660 relief valve the expansion tank and an 00:00:40.61000:00:40.620 additional valve he was going to charge 00:00:42.86000:00:42.870 over $1,000 just ridiculous I went to a 00:00:48.04900:00:48.059 local plumbing supply house but the two 00:00:51.26000:00:51.270 components though that I really needed 00:00:52.88000:00:52.890 which was the overpressure relief valve 00:00:55.04000:00:55.050 and the expansion tank and with tax I 00:00:59.00000:00:59.010 spent I think was 90 6.36 cents so doing 00:01:03.88900:01:03.899 this yourself is very easy and you can 00:01:05.84000:01:05.850 literally save hundreds of dollars so 00:01:08.92900:01:08.939 first off if your boiler is leaking and 00:01:11.89900:01:11.909 dripping consistently first just try to 00:01:14.51000:01:14.520 play with that overpressure relief valve 00:01:16.19000:01:16.200 a little bit it will tab on the end of 00:01:18.44000:01:18.450 it sometimes just resetting that 00:01:20.76000:01:20.770 that Valve and stop the leak if that 00:01:23.58000:01:23.590 doesn't fix the problem then it's best 00:01:26.42900:01:26.439 to change not only just the valve but 00:01:29.07000:01:29.080 also the expansion tank now sometimes 00:01:31.53000:01:31.540 you can tap on the expansion tank and 00:01:33.48000:01:33.490 and tell whether there's water in it if 00:01:35.55000:01:35.560 there's water in it then the expansion 00:01:37.02000:01:37.030 tank is definitely man 00:01:39.06000:01:39.070 you may want to just change the 00:01:40.52900:01:40.539 expansion tank and not change 00:01:43.76000:01:43.770 overpressure-relief valve but it's an 00:01:46.91900:01:46.929 easy enough job in a inexpensive enough 00:01:49.16900:01:49.179 job you start by turning off the burner 00:01:53.57000:01:53.580 then you're going to find the water into 00:01:58.55900:01:58.569 the border and turn off the water supply 00:02:00.69000:02:00.700 to the burner the next step in the 00:02:04.49900:02:04.509 repair is going to be the drain the 00:02:06.44900:02:06.459 system will drain the burner it is 00:02:08.69900:02:08.709 usually a valve located at the very 00:02:11.00900:02:11.019 bottom a drain 00:02:27.00000:02:27.010 you can't really walk away from it you 00:02:29.23000:02:29.240 have to stay with it and it has that 00:02:30.88000:02:30.890 five-knuckle you'll fill up pretty 00:02:32.50000:02:32.510 quickly and then help you cut off the 00:02:34.45000:02:34.460 album once the system's drained it's 00:02:39.10000:02:39.110 very similar you can believe I'm just 00:02:41.44000:02:41.450 unscrewing an additional extension pipe 00:02:44.56000:02:44.570 that they had on the bottom of my relief 00:02:46.57000:02:46.580 valve so remove that and then remove the 00:02:50.68000:02:50.690 actual valve itself my plan is basically 00:02:53.71000:02:53.720 to remove all the overpressure-relief 00:02:55.96000:02:55.970 valve and the expansion tank and take 00:02:58.33000:02:58.340 both with me to the plumbing supply 00:03:00.10000:03:00.110 house so they could give me the exact 00:03:02.71000:03:02.720 duplicate parts that I needed the 00:03:07.96000:03:07.970 overpressure-relief valve just screws 00:03:09.49000:03:09.500 off you will need to pick up some teflon 00:03:12.37000:03:12.380 tape in addition to the valve and the 00:03:14.98000:03:14.990 expansion tank 00:03:18.78000:03:18.790 now the valve oh I'm sorry the expansion 00:03:21.63000:03:21.640 tank just screws off but you have to be 00:03:25.14000:03:25.150 a little bit careful if it does have 00:03:27.14900:03:27.159 water in it and it sometimes they're 00:03:29.55000:03:29.560 completely filled with water they can be 00:03:31.50000:03:31.510 very heavy it's a little it caught me by 00:03:35.75900:03:35.769 surprise at how heavy this tank was 00:03:37.41000:03:37.420 probably 30 or 40 pounds 00:03:39.17000:03:39.180 so spin it off with two hands and make 00:03:42.89900:03:42.909 sure you're ready for the weight of 00:03:47.03900:03:47.049 course it's the tank is empty it will 00:03:48.69000:03:48.700 weigh hardly anything but the fact that 00:03:51.21000:03:51.220 he had water in it there basically means 00:03:53.39900:03:53.409 that that tank is may have a little bit 00:03:57.93000:03:57.940 of dripping out of the system we're 00:03:59.84900:03:59.859 going to move that tank now these are 00:04:01.50000:04:01.510 the replacement parts I went to the 00:04:03.33000:04:03.340 plumbing supply house they gave me a new 00:04:06.36000:04:06.370 overpressure-relief valve wrapped wrap 00:04:10.71000:04:10.720 the pipe with a little bit of teflon 00:04:12.11900:04:12.129 tape screwed it into position and use 00:04:14.67000:04:14.680 the wrench to tighten it up don't 00:04:16.46900:04:16.479 tighten this overly tighten up it's just 00:04:19.34900:04:19.359 the brass fitting and you can certainly 00:04:21.93000:04:21.940 crack it if if you over tighten it 00:04:37.80000:04:37.810 and I also replace the extension pipe 00:04:41.62000:04:41.630 that comes out the bottom and just make 00:04:43.72000:04:43.730 sure the water goes into the bucket not 00:04:45.40000:04:45.410 all over the place and then I'm going to 00:04:49.36000:04:49.370 replace the expansion tank same thing 00:04:51.90900:04:51.919 with the expansion tank just a little 00:04:53.35000:04:53.360 bit of teflon tape on the threads and 00:04:57.24000:04:57.250 then this just screws into position the 00:05:05.35000:05:05.360 teflon tape is just to assure that it 00:05:07.09000:05:07.100 that the threads themselves don't leak 00:05:18.03000:05:18.040 new tank is much lighter because it's 00:05:21.15900:05:21.169 not filled with water this just screws 00:05:23.20000:05:23.210 into position and you can just use a 00:05:24.85000:05:24.860 wrench to tighten it up a little bit 00:05:34.40000:05:34.410 once that tank is on and snug 00:05:39.98000:05:39.990 you can then kind of reverse the 00:05:42.27000:05:42.280 sequence you want to put the water back 00:05:45.18000:05:45.190 on make sure that there is still a 00:05:47.49000:05:47.500 bucket underneath that drain put the 00:05:52.23000:05:52.240 water back on to the burner over to the 00:05:55.14000:05:55.150 boiler now I I took out probably three 00:06:00.99000:06:01.000 or four gallons of water if you want to 00:06:02.64000:06:02.650 let some run Food Systems make sure it 00:06:04.50000:06:04.510 wasn't any air pockets then you can turn 00:06:06.87000:06:06.880 off that valve and at this point you're 00:06:08.85000:06:08.860 ready to turn the burner back on 00:06:22.46000:06:22.470 so here the burner is back on I've 00:06:25.22000:06:25.230 checked for leaks there's no water 00:06:27.14000:06:27.150 coming out of the overpressure relief 00:06:28.37000:06:28.380 valve there's no water coming out of the 00:06:30.37000:06:30.380 threads to the valve or the threads to 00:06:33.56000:06:33.570 the expansion tank so the repair is 00:06:35.78000:06:35.790 complete and literally saved hundreds of 00:06:38.03000:06:38.040 dollars please check us out on the web 00:06:40.04000:06:40.050 at DIY easy crafts com be sure to check
