Solor pool pump problem

I have a 3/4 horse pentair pump. it was pre-plumbed by my pool builder who is now out of business. I installed my solar heater myself and when i originally installed it on my roof aprox 12 feet off the ground i did not put a check valve after the pump. The basket will no fill with water completely but there is water flowing. there are two inlets in the bottom of my pool and I can barley feel the water coming out of one. before the company went out of business they told me the since i didn't install the check valve after the pump that the back flow of water into the pump has caused the pump now to run in reverse. doesn't sound right to me. they said the something needed to be replaced and they would send someone out. they never did. any thoughts?

Hi richkline1,

I'm Harvey the Master Plumber.

Your problem is: You have a 3/4 horse pentair pump. it was pre-plumbed by your pool builder who is now out of business. You installed your solar heater yourself and when you originally installed it on your roof aprox 12 feet off the ground you did not put a check valve after the pump. The basket will no fill with water completely but there is water flowing. there are two inlets in the bottom of your pool and you can barley feel the water coming out of one. before the company went out of business they told you the since you didn't install the check valve after the pump that the back flow of water into the pump has caused the pump now to run in reverse. doesn't sound right to you. they said the something needed to be replaced and they would send someone out. they never did. any thoughts?

I've been thinking about your situation for a few days. First install the check valve. If the problem persists then I would suspect the pump. I have seen a few times that the pump was not the problem. In these cases it was something I call an air lock. It is dificult to explain to the layman but it can be responsible for the lack of flow. It has to do with the way it is piped. I know it seemed simple to pipe but if not done correctly you have this kind of headaike. To solve this I would have to be there. Wish I could do more.

Pentair mastertemp pool/spa heater


Yes, Pentair does make a MasterTemp model heater.

Is that what you needed?

If not, I can keep on guessing...

  • Yes, MasterTemp can be used on a pool, a spa or both.
    • It has a Dual Temperature control, for two separate bodies of water.
  • These heaters come in both types of Fuel consumers: Natural Gas & Liquid Propane Gas
  • You do need to supply electricity to them
    • the supply can be either 120 volts or 240 volts
      • a simple change of a supplied plug
  • If installed indoors you need to vent through the wall or roof
    • Adequate ventilation is required for proper combustion of "Free Air"
  • If installed outdoors, no extra labor required, ready to go
  • Plumbing is simple, just plumb provided unions onto PVC pipe of your system, match up the alignment to the heater & tighten the unions, done.
So sorry, don't mean to be facitious...

But we could use more information to assist you. Your question was sooooo generic.

check the impeller for debris. you will have to take the metal band off that connects the wet end to the seal plate. inspect the impeller for debris. lube all o-rings and reassemble. if that does not work, investigate a blockage in the suction side plumbing.

Need to replace gas spa heater. Is there a combination gas and solar spaheater


You may actually use any pool heater with a solar water heating array. I do not however know about any that come as a package deal. You will need a solar array, a solar controller, a actuating valve to hook to the solar controller, and a new bypass assembley for the plumbing system. All of this is made by manufacturers such as : Jandy, Pentair, Raypak, Lasco, Buderus, Hayward, etc....

Both of those heaters are fine I prefer the Pentair for it's smaller footprint and ease of installation as you can turn it for access to plumbing. The Hayward is tougher to turn the exchanger on and you only have right or left as options for the plumbing to come out. Sta-Rite is still my favorite for installation being easy to plumb, wire and run gas to. It's very easy to change from natural to LP also.
Most heaters today are the same in reliablity and that is mostly up to you to keep the chemicals correct. Being in the business I always look to ease of install and access for repair.

How to setup a diverter valve for above ground


If you want all your water going thru the solar heater before re-entering the pool, you'll need to plumb the end of your filter to the solar heater, then the water exiting from the solar heater would go where the filter hose did go back into the pool. Hope this helps.
