Title says it all -- ~6 year old WM97+ with the domestic hot water kit add-on. Operation appears to be normal except that it's started leaking a pretty healthy amount of water from the internal expansion tank. What has me quite confused is that it's crystal clear water -- this is in a house...

Do you happen to have a link to the tape?

Based on that (who would have thought local government was putting out useful information) I think it's lead, which is not a surprise given the age of the house. The solder bulb is the giveaway, I'll give it a gentle scratch at some point

Nobody?

I've attached a picture of where my main municipal water line enters my basement through the floor. I don't have any problems with it, but until recently the hole was sealed by some packed in rags covered in spray foam... this was not great to look at so I figured I would investigate. I believe...

I totally get what you're saying -- and I'm absolutely not touching anything without the contractor's blessing. The pre and post pump times seemed unlikely to do any damage, and I reset them back to the way they were originally after concluding it was doing nothing. What I'm looking for is...

Hello - had a WM97+ installed this past fall along with its paired AquaLogic DHW indirect heater. Issue I am having is that when transitioning from making dhw to then heating the house (single zone) it is locking out with return water registering as hotter than supply water. This issue seems...

Thanks for the info. I'm pretty confident that the AquaLogic will cut it -- we have 1 shower and 1 tub/shower -- the latter of which has been used a handful of times. That said, the AquaLogic is capable of filling a tub, right?

Looking to replace a ~30 year old boiler with a new one with domestic hot water. Caveat: has to be a direct vent unit as I would otherwise need to reline the chimney. I've gotten bids on the following units -- the pricing for all has come in around the same +/- 1) Weil-McLain ECO with a 45...

Do you by any chance know of a resource where I might find detail drawings for things like dormers with the additional roofline thickness?

Another thought I've had, something like this: http://www.raycore.com/images/vented-sip-panel.png (Ignore that the picture is a SIP panel) In this case it would be, existing insulation remains, seal over current decking, furring to create an air gap, new ply or osb over the whole thing...

Ok, 3" seems a bit more reasonable, I'm not entirely sure what's in the bays at the moment, I'll check over the weekend. A question though, how does this change the fascia profile? Seems like it's going to involve a fair bit of construction to make it work. Something like this...

Dana strikes again :-) Thank you for the insight into the complete reason behind roof ventilation and why it's now a concern once the slate is removed. I like the EPS foam option, namely that it keeps me out of the crawlspaces, but 5" is quite a bit and I'm wondering how complicated that...

I agree -- which is why I'm looking to remove the insulation from the rafter bays when the new roof goes on. I think the insulation in the bays was vaguely acceptable with the slate as air was moving through the roof pretty readily, thereby preserving the decking.

Unfortunately, nope, not in the budget. A) It's a big roof B) Anything but asphalt or slate is very rare around here. The slate has lasted 90+ years which, as I understand it, is the anticipated lifetime of this particular variety. I'd love to replace it with new slate, but that's not going...
