Take a look at the pix: Should there be a check valve in the supply line below the 3 way valve and a check valve in the return line above the shutoff valve?

When the Hayward automation system (pro-logic) switches from one group to another group, the pump shuts off for 30 seconds and the solar valve closes; 30 seconds later the pool pump turns on and the solar valve valve opens. At that moment the vertical pipes going from the pool pad to the roof...

I have a Jandy check valve with the clear cover that about 1.5 years old. The spa was leaking into the pool so I took the cover off of the check valve and the red flapper is discolored and peeling but more importantly part of the red flapper seems to have melted onto the black body. There is a...

When I close the valve to the skimmer and only use the main drain, the pump basket does not fill up and I'm getting quite a bit or air in the filter; I can purge the filter and come back 30 minutes later and air is in the filter. I do not have a separate valve for the main drain and skimmer...

I'm using the Hayward Sense & Dispense and OPR control; the tube for the influent is after the 4 cartridge filter. When I'm testing for chlorine, the difference between the pool water and the test cell is about 4 ppm (pool water higher than test cell, 2.0 vs. 6.0). I've tested for adequate...

The breaker/relief valve is not at the highest point of the piping on the roof but rather on the supply side piping near the equipment pad. The installer told me "that's the way we do it around here, if the valve leaks/fails, it's easier to replace the valve at ground level instead of climbing...

I asked the solar installer why he installed the check valve on the supply instead of the return and I was told it's a new law/requirement that the check valve be installed this way; they used to install the check valve on the return but not anymore. This doesn't make sense to me. Also, if a...

Hi - I'm using the Sense & Dispense system with a Goldine Pro-Logic controller. The reading of the pH in the test cell of the Sense & Dispense does not agree with the pH reading I get in the pool. The test cell reads less than the pool, usually about 0.2 ppm less. Is this normal? Can this be...

I'm using the Hayward Sense & Dispense system with a Goldline Pro-Logic controller. I adjusted the pH level in the Maintenance menu from 8.0 to 7.8 and now I'm getting the "pH Calibration Error - Check System" message. The manual states that I will get this error if the test result is different...

I have a Hayward Ecostar VS pump that is controlled with a Goldline Pro-Logic using the communication interface. I read in a post on this forum that the pump should be wired directly to the breaker and not wired to the Pro-Logic pump relay: 1. I'd like to know if wiring directly to the breaker...

I have several Jandy 3-way valves that have 2" pipe over the outside of the 1.5" inlet/outlet ports; I would like to be able to reuse these valves and I was wondering if there is a way to remove the 2" PVC fittings on the ports.

I have a some questions about the Hayward Sense & Dispense system: 1. When I open the test port, no water comes out. Am I supposed to open either one or both of the effluent or influent valves at the same time? 2, Is the pump supposed to be off when opening the test port? 3. Can I install the...

I installed Hayward Ecostar pump and I'm getting the "check system pool bridge comm" error message. This message only appears for a fraction of a second maybe every 3 minutes. What's interesting is that when the pump is running at 100% the error message appears more often, then if I reduce the...

I'm using the Hayward Pro Logic Controller, with the Aqua Rite salt generator and now it's time for me to replace my Sta-Rite pump and Sta-Rite filter. The Pro Logic Controller I have has the correct firmware to handle the Tristar VS pump and I was going to add the Swim Clear filter. I have a...

I would like to change the filter and pump for my in ground pool. The pump and filter are original since 1995 however the pump motor was replaced prior to my ownership by the previous homeowner and now the pump is beginning to leak. Here are the stats of my current pool system: 20,000 total...

I've been using this unit for testing my pool water and I have a question regarding the calcium hardness test. I have a plaster SWG pool. When testing for calcium hardness and waiting the recommended two minutes before testing, I get initial readings in 280 ppm CaCO3 range. If if then continue...

I would like to change the filter and pump for my in ground pool. The pump and filter are original since 1995 however the pump motor was replaced prior to my ownership by the previous homeowner. Here are the stats of my current system: 19,000 total gals: 18,000 gals pool, 1000 gals spa Spa...

I installed a Stenner acid pump with a Sense & Dispense system from Goldline. There is a 2 hour timeout feature that will stop the acid pump from dispensing acid if the target pH is not met. When there is a call for acid, the acid pump will only run for about 8 seconds and then shuts off and...

I have a 20,000 gal, in ground pool with a Sta-rite 1.5 hp pump and a Sta-Rite cartridge filter. In the past I would attach a garden hose to one of the drain ports on the filter housing and wait 1.5 days to the lower water in the pool. Would this setup work better? I would install a shutoff...

I installed a Stenner variable speed acid pump with a #1 pump tube that discharges a maximum of 5 GPD on a #10 pump setting (maximum). I'm diluting the acid 4:1 with water. I'm also using a Goldline controller which has a 2 hour maximum run time for the acid pump. I'm trying to lower the pH...

I have a outdoor, 21,000 gal plaster pool, screened cage, no pool cover, solar heat, SWG, cartridge filter, sense & dispense system, Goldline controller in SW Florida and I like to keep the FC level at 3.5. I don't understand why with an ORP sensor/probe system the recomended CYA level should...

I'm going to be installing a Sense & Dispense system that has a SWG, a cartridge filter and Goldline ProLogic controller. My question is regarding the plumbing of the effluent tubing of the probe cell to the pool supply/suction side of the exisitng pool plumbing. The installation manual shows...

I will be installing a Goldline Sense & Dispense system and using a Stenner 5 gpd variable speed pump with a #1 tube. I am using a SWG with a Goldline PS-P8 controller. I have the following questions regarding this setup. 1. Is diluting the acid with water necessary or is it just to avoid fumes...

Has anyone used this http://www.palintestusa.com/products-details.aspx?id=3 and what are your thoughts about it? I've been using the Taylor K-2006 but I was thinking that the Palintest would eliminate the "subjectivity" of the reading and replace it with a digital readout.
