Insulating pex lines for a new whole house system. K-Flex closed cell foam with adhesive is $8.60/6’ length, and H.D.’s Everbilt is .78 per 6’ length, no adhesive, but I’ve got plenty compatible tape. Is there any reason to even consider the K-Flex? Thanks, Dan

I’ve got to install a direct vent lp unit and would prefer Bradford White’s model, but can get AO Smith’s unit for $350 less. Specs are nearly identical on both units. Is the up-charge on the BW worth it? Thanks, Daniel

installing 3/4 sch40 black steel, and my Toledo dies weren’t cutting very clean threads. Teeth were sharp and undamaged, but I went ahead and bought a new Ridgid 12R threader, since Toledo doesn’t make the old die design anymore and I figured the dies were more dull than I thought. I hadn’t used...

I’ve got several ridgid pipe cutters - 3 and 4 wheel cutters - that were my father’s, and I bought a replacement set of cutting wheels for the no 2 cutter (same as today’s 2a). I was surprised to see that the wheels have a more blunt edge than the old wheels I took off, which are relatively...

Does a reduced port ball valve have much if any effect on flow? My understanding is that the port reduction has an effect on water, but no so much on gas. Is this correct? I can’t find anything regarding this in the National code, and when my local gas company made the connection between my...

Trying to find out what the total length is of the expandable vent for AO Smith’s GDV-40 water heaters. AO Smith customer service says they don’t know and to reference my supplier who also doesn’t know. Checked with my hvac supplier who can get the part, and he says there’s no info and when he...

Trying to apply some solder to the pinhole leak in the tubing on my Bosch water heater heat exchanger and it beads and rolls right off. Yes, I cleaned it, buffed with emery cloth and fluxed. It looks like copper, cleaned up and sanded like copper, but no go on the solder. No problem at all...

I'm looking at a new construction installation of a PEX home-run system, and I'm seeing some big price variations between PEX brands. Apollo and Bluefin are substantially lower priced than Viega (all type b) but overall, Uponor, Viega are priced substantially higher than their competitors. Is...

My need is for a sealed combustion, direct vent, no electric requirement lp water heater and the gdv-50lp meets all the criteria. I believe Bradford-White makes one too, but they're currently on backorder for a while and priced higher that the A.O. Smith model. Is there a similar unit out there...

Could it possibly be as difficult as it seems to find a replacement pitless o ring? My plumbing supplier - a major supply in the nearest city sold me my harvard pitless 14 years ago and has no replacement o rings for it. Their suggestion is to install a whole new pitless! My pitless is too deep...

I'll be installing a new submersible in a day or two. The pump installer that helped me with my old submersible used direct burial wire and it needs to be replaced. Is the submersible cable I see online any different or more appropriate for this application? Thanks

I'm wondering if it matters how a spring loaded brass 1 1/4" check valve is oriented - horizontal or vertical.

I've had an ongoing issue with my water system that I could use some input on... I have a low flow 24v dc submersible set at 40' below static water level (max allowable depth is 50') Well depth is 160' in bedrock. Drop pipe is 1/2" (required) and from the pitless to my tank I have 3/4" k...

I'm at 1700' elevation and drawing 12' vertical using a 1/2 hp pump , 1 1/4" pipe, and a well point. This services a camp with low water demand. I'd like to replace the old galvanized with pex or black poly and move the pump as well. I can't locate anything other than 3/4" pex, but can get...

Noticed my pump running during the night when there hadn't been any water usage, then checking things out in the am discovered that the check valve had a fine split running from the end of the threads towards the middle. An inch long. I don't think I tend to over torque, but aside from that...

I have to splice in a short section of underground tubing between 3/4 k copper and a pitless. Is my best bet for a sound and worry free union sweating in a section of k copper with a coupling, or is there a more "bullet proof" approach that I can bury and not fret over? Thanks

I need to install a saddle tee on 3/4 k copper so that I can install a pressure gauge. Max pressure on this line won't exceed 60 psi. Because of existing constraints I can't cut and sweat a fitting so the saddle tee is the only way to do this... so far as my knowledge goes. My question is...
