@ 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!

@ 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.

Liquid side of A coil sweats bad. Top clean.

@ 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!

@ 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.



@ June 18, 2013 12:29 AM in Old style toilet flush valves

I'll take pics later. Great toilet. Long days. I covered all the basics but did not consider the plunger shape. The flush valve is new so no corrosion possibility.

Thanks for the advise!


Old style toilet flush valves

@ June 16, 2013 7:38 PM in Old style toilet flush valves

Installed a Standard Moderno 1927 toilet in my basement. Used a new spud and flush valve / plunger.

It constantly allows the tank to drain. It's not the threaded connection to the overflow tube.

Does it need more water in the tank to hold the plunger down tighter? I don't want to use pool & spa lube with new parts. I've only got the tank filling half way or a bit more.

Happy fathers day!


Piping question for Quietside boiler / tankless install..

@ June 5, 2013 1:05 PM in Piping question for Quietside boiler / tankless install..

So I am installing a Quietside 120 in my own home. One of my two 40 gal went down and I just did not have the heart to simply plop another tank in there. I need space and want the high-efficiency as well.

My house is about 1700 sq', maybe 80k heatloss and I added some rads in the unfinished basement so including that maybe 100k. I have a front & back zone.

With 3/4" taps from the boiler, since I am zoning and may wish to add a zone some day, wouldn't a 2" manifold / buffer tube under the boiler with a primary pump be the best way to keep flow up? Then maybe 1" manifold off that for supply & return and mix in the buffer?

Thanks,  Tim


@ May 2, 2013 11:27 AM in Old building DHW recirc system

I'll post pics and a schematic later.

3 Lochinvar tanks in parallel, 1.5 out and a .5 back from each side really is all I can see. At the return termination it ties into the cold water makeup line that feeds all 3 tanks in parallel. On some hot water calls the cold water is drawn backwards through the pump and mixes in the recirc line. It's that Backflow or mixing I need to stop. The temps on my returns are great now since I found nearly totally blocked iron pipe in both directions. With that removed it is recirculating great. Uninsulated iron pipe. Lots of heat loss.

Since I was asked to deal with the recirc issue I have not checked tank temps yet. I'll do that as part of my checklist today before wrapping up. Camus mod con is making the DHW.


@ May 1, 2013 11:46 PM in Old building DHW recirc system

So the 15-35 or the 0014 are too big? The 15-35 is 3 speed.

Any thoughts on the recirc termination? Maybe move it from the hot water makeup to the to the hot water supply?

Found issue

@ May 1, 2013 8:38 PM in Old building DHW recirc system

There is a spring check on the suction of the pump. If the pump is running it is open. If there is a large enough call for hot water, cold make up water cheats backwards against the pump and into the hot recirc line! Should I dump off my recirc somewhere else or rearrange the check system? If I choke the iso flange off enough it doesn't Backflow but I loose recirc capacity.

Single handle faucets..

@ May 1, 2013 7:26 PM in Old building DHW recirc system

Can someone help me grasp in what circumstances single handle fixtures effect a recirc system like this? My returns both got really hot after I replaced all the plugged pipe around the return then one side got cool, felt mixed.
