Need help with water service noise / banging....

@ October 26, 2013 2:31 AM in Need help with water service noise / banging....

So my old setup was just pipe, an old valve, and iron pipe into the water heater, 40 gal. No checks, xtank or anything. Never a problem.

New system is all copper, tankless, x tank, PRV, and filter on service with gauges before & after PRV. At night, I noticed constant banging throughout the house. Few days later, I realize it's all day, and it's the water service. Gauges show pressure coming in at 78, house set to 65. Incoming pressure varies a few lbs, then dropped to 65 or less, and when it recharged it banged my pipes hard. This happened over and over. So I call the City. We watch the meter as it "breaths" in & out against my x tank. No check on the meter or yolk.

So I install a swing check first thing in line inside my house. Now, I can hear the banging of the service drop and recharge, but my gauges stay firm. Much, much quieter (faint) but rhythmic and constant. Thump, thump, thumpthumpthump, thump.

My concern is how this affects my 100+ year old service line. Now I see more & more rust in the house filter.

Can I demand a check at the meter??

Cross contamination

@ September 28, 2013 6:01 PM in Dirty Steam Water in Hot water tank

High pressure leaks into low pressure side. If you flushed or refilled a hot steamer you can cause a leak in the boier, but not cross contamination. First sign of coil leak is press relief valve on boiler trips. Tank rotting? Sat for a while?


@ September 21, 2013 1:18 PM in Help: Leaking Drain Pipe On Side Of Furnace

Best approach is to clean the pan, drain, and COIL. Lowes sells coil cleaner, I forget if it's indoor coil approved. If its never been opened or cleaned, do yourself an hour or two favor and check / clean your A coil. Access door comes off front of insulated box then an access door to see into the coil. You'd be surprised at what I've found in there. Sometimes solid sheets of dog hair or big yellow stains from smokers.

That is the condensate drain for the AC coil. It can be backing up and partially or fully blocked. It's just sprinkler pipe PVC. Cut it, clean in both directions, glue a coupling on it, done. You can try using a shop vac to suck it out but I use compressed air and blow them out. Common issue.

Lots and lots of excellent reading material under 'shop'. Well worth it to get their feet wet / socks steamy.

Hope all's well & dry Mark!!

H2O quality

@ September 18, 2013 10:14 PM in Aluminum VS stainless steel.

Its about pH. AL exchangers need a neutralizer here.

Different design as well.

I pulled 2-3 cups of crap out of a WM Ultra HX with a hack saw blade last week. Night & day performance increase.


@ September 18, 2013 8:37 PM in Tankless piping 101...

So far (2 months or so) it's made hot water every time, but I'm piping the boiler pipes now. I need to figure out how best to control a mod-con with a tN-4 where the reset is in the control, not the boiler. Boiler just has a couple leads and that's it.

Very quite and compact. Pics in an hour or so when I'm done for tonight.

1.5 mil BTU or so.

@ September 18, 2013 3:06 PM in Action pics, let's see yous guys!

Built a base next to the base to slide sections over.  Not too bad. Cleaned up well.

I did pitch 1A ball about 25 years ago!



@ September 18, 2013 3:01 PM in Tankless piping 101...

When it's been running, and making hot water, if you turn off said hot water for EVEN A SECOND, you get a 'sammich' of hot left in the pipe, cold from start up of tankless, then hot again when it picks back up. Very annoying in certain situations, and when the front loader washer calls it does not really get hot water since it uses pulses of water to reach it's weight.

This business will get out of control. It will get out of control and we'll be lucky to live through it.......


@ September 18, 2013 2:03 PM in Tankless piping 101...

Do you mean the balancing valve? We have a shower only downstairs and a 2-handle style clawfoot upstairs. If everything is off, then a toilet gets flushed, it kicks on the tankless but not long enough to fire it.

I do have a new shower fixture to install as part of this entire upgrade. Old one was living on iron pipes for 8 years now. Wanted all new and am installing a bypass and iso valves to have a hand sprayer for a dog washer. Just ran all new copper, entire house, added x-tank for DHW.

New flow port gaskets. Need more jobs like these.....


Tankless piping 101...

@ September 18, 2013 8:11 AM in Tankless piping 101...

Installed a Quietside combo a couple months back, great machine, but.....

1...Kicks on with toilet flushes. Just starts. Will a check valve stop this? Best type, placement?

2...Cold sammich. Toilet flushes kill the hot water and it has to restart. No good. Going to install a 6-gal WH to defeat the sammich. Any way to do that tiny tank solar?

Install pics later. Starting heating pipes today. Thanks!


Wet bulb

@ August 24, 2013 2:54 PM in 410 help needed!

67* in house.

My liquid line was 300 psi. Coil sweats super bad.

82* and 35% in the house. Bottom of coil super cold. Top hot.


@ August 24, 2013 2:09 PM in 410 help needed!

Liquid side of A coil sweats bad. Top clean.

410 help needed!

@ August 24, 2013 1:59 PM in 410 help needed!

Helping a friend diagnose 410 system but I've only done one.

Suction temp 68*, 78* day, liquid pressure 230, suction pressure 115, and top of coil is 68* or so and bottom of coil is 45*. Lots of air flow. TXV installed but non adjustable. Small Rheem system. Have not looked up the size but maybe 1.5 ton. Small.


@ July 15, 2013 12:35 AM in 3-way mixer under tankless??

My rep at Hajoca recommended a mixer, but I posted this because I've never used one on a tankless, just a tank.

We have a 2-bath house, and the shower we use has a nice higher-flow head, but we will never run 2 showers together or any two fixtures really. Sounds like I don't need the additional part, which is good.

The valve is a Taco that was on their close out table but has a tankless diagram on the box showing that valve on a tankless.

Thanks, Tim

3-way mixer under tankless??

@ July 14, 2013 7:43 PM in 3-way mixer under tankless??

I'm finally doing some near boiler piping and connecting new copper from the house to my Quiet Side 120k. It's fun trying to make 4 tappings that are 2-3" apart look nice!!

So the tappings for tankless are 1/2". I want to do what I can to increase performance, so I'm planning on using a 3-way mixer. Any thoughts on this?

I love the easy math questions!! 0-0=0!

HD ads

@ July 6, 2013 9:13 AM in Professional?

Remember a few years back when someone posted the ad of the guy installing a water heater and was using a map gas torch pointed right at one of the flexible connectors, and the WH was on a flimsy wood platform.

I believe the winning comment was that they could not get it to light so the torch was their only option to get the customer hot water.

I have like 4-5 rads

@ June 23, 2013 9:25 PM in Looking for 2" push nipples for cast iron radiator

That a cust said I could have. Their demo guys took the rods out and split them up. Super mad.

The end result is I have 20+ sections, each with 2 nipples. If mine are your size, we can talk. I'll make it very painless for you!



@ June 23, 2013 9:17 PM in Old style toilet flush valves

Yes. Ashamed to admit, that's what we had!! Not a single recharge since I snipped the tube. The funniest thing is I went down there and heard it drip. I figured it had recharged and was just letting a few drops out. Then I pulled that tube out from the overflow tube and looked in there but could not see any signs of leaking at all. With the tube out, no leaking. Then stuck tube back in and hour later, recharge.

Thanks! Heard the email because I am subscribed. This toe thing and a bruised heel opposite foot has made me hopelessly behind.

I don't shop on Sundays so a brick or 3 tomorrow!! We really appreciate the advise. Love that toilet. I've had it for years. I'll take an inside pic later. No idea what the others look like. We love the Deco look of this. Classic!



@ June 22, 2013 2:07 AM in Old style toilet flush valves

Well, I broke my left pinky toe. Man what pain.

Back to the toilet. Tried round and straighter wall balls but round leaks slower. Tried pool & spa grease and that helped, but wrong road.
