    Anchoring Hose Bib into Concrete Block

    Well, I ended up using Tapcons, and they were about as crappy as ever, but I managed to get the hose bib anchored. If the hole spacing on the bib was a little wider, it would have gone a lot better. By the time you drill out a large enough hole for the 1/2" galvanized, there's not much meat...

    Anchoring Hose Bib into Concrete Block

    What's the best type of fastener to use to anchor a hose bib into concrete block? I've got one that needs anchoring but it appears that the holes for the fasteners have to be very close to the hole for the pipe that I had to drill. I used galvanized for the bibs because I needed to go through...

    Recirculation Pump Installation Questions

    Any tips as to the best solder and approach to use regarding sweating a piece of 3/4" pipe to the inlet of the pump? I'm a certified weldor, but whenever I have to solder plumbing pipes, I get nervous.

    Recirculation Pump Installation Questions

    I think what I'll do is fill it with water and set it up so that the output that I'm soldering to is on the top. If I work quickly, I think I'll be OK.

    Recirculation Pump Installation Questions

    Thanks very much for the reply. I wasn't sure of the nomenclature for what I needed to buy. Are there any pitfalls to watch out for when sweating a fitting to the pump? Should I remove the impeller assembly, etc. or fill the pump with water so it doesn't get overheated? I've sweated plenty...

    Recirculation Pump Installation Questions

    Yes, I have a dedicated return line that I'm installing. Any comment regarding if it's best to put the pump on the outlet of the WH or to put it on the return side close to the drain bib?

    Recirculation Pump Installation Questions

    I'm curious about the best way to install the Grundfos pump that I bought. The outlet of the pump is a 3/4" union fitting while the input has a 3/4" sweat connection. I'm planning on having the return go back into the water heater through the drain on the bottom after adding a tee and...

    Designing Expansion PEX Layout and Brands to Use

    What sort of thermostat would you recommend? I could see using one in conjunction with the light switch so that the pump would turn off when the water at the bathroom came up to temperature.

    Designing Expansion PEX Layout and Brands to Use

    My thoughts about having the pump run whenever the bathroom light are that it wouldn't be an excessive amount of time as some systems run the pumps for hours a day when using an adaptive, pre-programmed controller. I would be happy using some sort of relay system whereby the lights coming on...

    Designing Expansion PEX Layout and Brands to Use

    I'm not looking at keeping the water hot all of the time. I'm interested in having the pump come on when the light switch in the bathrooms is switched on. Lights go off and the pump goes off. The full bath/laundry room only has one window and the light would have to be turned on whenever...

    Designing Expansion PEX Layout and Brands to Use

    It looks like about 2.2 GPM if I'm reading the chart correctly. https://s3.amazonaws.com/s3.supplyhouse.com/product_files/59896241-brochure.pdf

    About 50 feet if I only include the full bath, and about 75 if I include the half bath.

    Designing Expansion PEX Layout and Brands to Use

    I've decided to definitely install a hot water recirculation system for the full bath. I may add the half into the loop, but I fear that there might not be a real advantage in doing so. I'm mainly curious about the pump I'm considering. The supply and return line (green in the photo) will be...

    Designing Expansion PEX Layout and Brands to Use

    I did some figuring and came up with this layout. I would like to wire in the pump so that it comes on when the bathroom light is on unless there's some compelling reason not to. I like the idea of the pump only running when someone is in the bathroom and not circulating hot water continuously...

    Vent Pipe Under Soffit?

    One reason that I didn't want to run up and around the eave is that there really should be a gutter on that facia. It can't be seen in the photo, but there's a roof valley that dumps quite a lot of water on the lower roof in one spot. That sort of situation has lead to premature leaking on our...

    Vent Pipe Under Soffit?

    I think the AAV option is going to be the easiest here as I won't be working in such a tight space and it will be easier to put the through-roof vent over the washing machine drain. I could use a through-the-roof vent for the washing machine instead of an AAV as I had planned (washer is on...

    Vent Pipe Under Soffit?

    I'm having some difficulty with placing the vent for the full bath wet vent that services the water closet, lavatory, and shower in our full bath. The only place the vent can be located if it goes through the roof is right under the soffit for the main part of the house. The bathroom was an...
