    What Kind of Cream Colored PVC Is This?

    In my area new pools always seem to be built using this cream colored 2” PVC. I want to use some but cannot seem to find it at any local distributor. Anyone know what this is or who makes it? Im thinking it might be CPVC?

    Return Re-Plumb Plan - Peer Review

    I'm looking to re-plumb the return side of my equipment pad. My goals are to a) add a manual drain valve for the rainy season since my ancient pool has no automatic overflow, and b) to add 2 injection points for an automated chlorine/acid dosing system. I didn't include a check valve because I'm...

    Taylor Reagent Expiration Dates

    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...

    Converting Venturi Spa Jets to Active Blower Fed System

    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...

    Using Intellicenter Valve Output to Control Stenner Pump

    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...

    Liquid Chlorine Dosing and Its Delivery Mechanism

    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...

    Pentair Union Confusion

    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...

    Bond Wire Coupling

    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...

    Spa Spillover Mode Valve

    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...

    Pentair Load Center Mounting

    I'm going to be replacing an old Intermatic dual-timer subpanel with a newer Pentair load center. Right now the old box sits about 2" above grade on two steel poles that are embedded in the concrete pad. The box is so low its a real headache to work inside it. I would like to extend the steel...

    Blower Troubleshooting on Spa Jets

    Hi all, I recently bought a home with a gunite pool/spa with a small spillway between the two. The pool is probably 1980’s vintage, but no one is quite sure how long its been there. One of the things Im trying to troubleshoot is the blower. It looks original and sounds like a jet engine, but the...

    EasyTouch Extra Relays

    Hi all, Im planning a build to add EasyTouch automation to an older pool/spa. I am looking at the PSL4 and am hoping to control these items: - Intelliflow VS main filter pump via RS232 - Waterfall pump via aux relay - Pool light via aux relay - Spa jet blower via aux relay - Polaris booster...
