Just picked up a 2oz bottle of r-0871 fas-dpd re-agent and a 10 gram bottle of dpd powder r-0870. Both sold by a third party seller but stocked/shipped by amazon. Only problem is, they both have a 6/24 expiration date, which is only 8 months away and not the 12 months Taylor advertises. Did I...

Thank you, I had thought of something similar and tried a 3/4" threaded sprinkler riser, but those threads are a bit different. The nozzles are just slightly smaller and their thread is finer than the 3/4 MNPT riser's. Using a die is not a bad idea though to get the threads just right. It...

Hi Mark, yes I do, I actually created this diagram to help one of the supply houses track down the nozzles and wall attachments with dimensions. One of the nozzles pictured is in OK shape, but the other two were very brittle and I had to break them out to get them out of the wall so they are...

I would ask the leak detectors for a complete accounting of what they tested and what might still be causing a leak. To completely test a pool would likely require diving to test light niches, possibly drain covers, etc. When I had a leak test done I was told the bucket is the most accurate...

I have a 40-50 year old pool and spa combo where the spa spills over into the pool. The 3 "jets" are actually connected to the return line from the filter pump (no dedicated jet pump) and they are venturi type jets. I have a 1.5" PVC air line running to an upside down P-shaped air intake near...

@Dirk, when you switched to suction side only did you find any difference in sediment levels, need to sweep more etc? I’ve always thought one of the biggest advantages to a pressure cleaner was the tail, the sweeping motion keeps fine sediment suspended where its more likely to get sucked into...

Pretty cool, especially with the probes. It would be very nice to automate away the seasonal adjustments. Bummer that there are no combined chlorine probes available with reasonable price. Since we only superchlorinate when needed the DPD-FAS test is a regular part of the toolkit. The...

The Stenner Econ-T and gray 7.5 gallon UV tank is $375 from a local supplier. I assume the $700 setup is the Pentair tank and pump? Is there any writeup about this?

Here is yet another possible solution to the problem: Use the Econ-T's built in timer function as the backup/safety that @generessler and @ajw22 suggested. The primary switching control is the Intellicenter - its 24v valve actuator output "Valve B" is scheduled to dose one time a day between...

A very good point - I work in the electric utility industry and it sure resembles a piece of ICS, but you are right it lacks key safeguards and feedback loops like a real ICS would have. IMO this equipment really should be built closer to ICS standards. There are significant health and safety...

That is a bummer. I think the Econ-T might be the safer bet then. Its pretty concerning that we cant trust an industrial control system like the Intellicenter. I could see a similarly bad situation where switching from spa mode to pool mode leaves the intake valve set to spa, draining the spa...

I'm using for liquid chlorine, and I agree 4 gallons of 12.5% chlorine would be a bad day! That would only happen once for me to scrap the whole setup. At least on the Intellicenter, the valve actuator is supposed to be linked to and run only with a circuit - an actual aux circuit or a feature...

Great information, thank you both. I'm thinking this will work perfectly with the Econ FP's auxiliary mode which activates on a continuous basis with a 24vac signal. If I get this working I will post a writeup.

After noticing that I have two extra valve outputs, but no extra relays, I thought maybe I could use a valve output to control my Stenner pump. That way I could schedule my dosing cycle along with a set filter pump speed as a feature circuit and set the dose time accurately in one place instead...

Its a fossilized mer-man. It's what I hope not to become from maintaining this pool =D

Im putting together a liquid chlorine dosing setup using a stenner econ-t pump with their 7.5 gallon tank. I’m injecting at the pool return line (so spa always gets non-chlorinated water). Since I have a new Polaris 380 running via booster pump I thought maybe the best time to dose would be when...

I'm replumbing my 1980's era inground 19k pool to add a flow meter, check valve, doser injection point. Unfortunately to make the modifications I need to make I will need to replace two unions: one the intake of my IntelliPRO VS pump, the second one the outflow port of a Sta-Rite Max-E-Therm...

Thank you that is just the part to do this job (y)

I have a bare copper bond wire that comes up to my pool pad out of the ground, and after the 8” that is exposed at the pad, the rest of the wire is completely encased in concrete all the way to the pool shell. What is the best way to couple a new piece of 8awg bare copper to this wire so I can...

Duh. Makes perfect sense now. Thank you Jim.

I'm in the process of adding automation (Intellicenter) to an older pool/spa combo. The spa has a spillway about 1" above the pool and historically, I keep the multi-port valve splitting the pool return and the spa jets just slightly open to the spa jets so the spillway operates 8 hours a day. I...

Thanks again, will try Inyo. If worst comes to worst and I cant find the right fittings, what about plumbing my floor bubbler blower to the passive vent line for the wall jets and just blowing air to both sections at once? Any issues having both floor bubblers and wall jets on the same blower...

Thanks @mas985 for the tip, I used a 1/2" socket to remove the nozzle/orifice out of 1 jet and took out the part that looks like the photo below. The other two were very brittle and the hex actually broke so I drilled two holes in the PVC and turned them out with needlenose pliers. The orifice...

Success! Thank you for that tip, I was able to draw water from the spa through the vent pipe, and blowing into the vent pipe with the shop vac I got plenty of air out of those 3 jets, so the line is open and clear. I think I just need 3 venturi attachments. I measured the inside threads at 1...

Yeah this is a strange pipe for sure. Never seen a pipe or conduit that looks like it. It has a very thick wall. If it is conduit, I would be hard pressed to fit 3 14 gauge wires through it at only 1/4" inner diameter. Likewise it wouldn't deliver a whole lot of water either. They are very...
