There should be a drain plug on the bottom of the header. This is common on most of Hayward's in-ground pool heaters. Since you did not give your model Number, I can't say 100%. You can also check Hayward's website for the manual and look under "winterization". you should be able to find your product manual here: http://www.haywardnet.com/inground/products/manuals.cfm#HeatersGas_Heaters Hope this helps. If you need further assistance post a reply in the comments, and don't hesitate to leave good thumb rating if you found this helpful. Thanks, and good Luck!

I have a Haywood pump and filter - S180t - I started it up after winter and I have no backwash or rinse pressure??


Did you drain it completely before Winter? If water was inside the pump, it could have been damaged by expanding freezing ice. The impeller could be trashed (i.e. ''physically broken'').

How to winterize the h100id1 hayward pool heater


Make sure that you drain all of the water out of the pool heater to prevent damage during freezing weather. That is the most important thing you can do to winterize pool heaters. If you have a cover, you might want to use it to prevent weather related exposure, but as long as you have the water out, you will be ok.

I need to winterize my Hayward 300. Where the manual shows a drain valve there is a thick square bolt. I'm afraid to compromise it if it is not in fact a bolt.


That is the drain plug...underside of the inlet/outlet header. You should also break open the connection of the water tube to the pressure switch inside the heater to prevent the switch or tube from freeze damage.

How do you winterize a inground pool heater? model# H200ed2 serial# 21130507102557001


Drain it using the drain valve on the bottom-side of the inlet/outlet header; make sure the heater sits level or slightly tilted down on the header side. You also need to drain the water tube that feeds the pressure switch inside the heater cabinet. Turn off the gas and power off the circuit and you are done. If you cover it DO SO LOOSLY! Wrapping it tightly and not allowing air to flow thru will lead to rapid rusting of all the sheet metal.

First year with my new Hayward H 250fd heater. Closing pool this weekend and live in Michigan so you understand our winters. What do I have to do other than opening the drain plug if anything.


Other than the drain you'll need to remove the pressure switch from its feeder tube and leave it hanging by its wires for the winter. Be sure the heater is level or tilted towards the header to allow all the water to drain out. More than a few people have lost a heat exchanger to freeze damage after draining it because the heater wasn't level and water remained in the low end of the tubes.

How do you winterize?


pull the three (or so) drain plugs in your heater ... use a shop vac (without the filter in it) to blow and then **** out any remaining water.

hopefully, your pressure and suction pipes lead away and down from the boiler. Make sure you **** out those pipes as well.

You know how to drain your filter(s) and pumps ... right?

I hope this helps you

POO; HEATER DRAIN HAY WARD G AS HEATER


Are you asking how to drain it? If so some older models come with a drain **** located on the bottom side of the black manifold. It is brass. You can loosen the drain **** and the water will drain out, be careful when tightening the drain **** back up though, they can break easily. You do not have to put much torque on it at all, dont even put a tool on it at first, if it leaks, then tighten it a little more. The newer models come with a brass plug instead of a drain **** and you can remove the brass plug. Or the best way i think is to unhook both unions for the inlet and outlet on the heater, use a shop vac on blow, and blow the water out. But if you are winterizing the pool equipment, the heater is not the only thing that needs to be drained.

Drain gas heater for winter


On the side of the heater, you will see the water connections. Directly underneath them, on that black component that they attach to, there is a drain plug of some description. It may be a draincock, or just a plug. In either case, simply open or remove it to safely drain your heater. In a pinch, you could also disconnect the water connections at those unions (the big grey connectors), but they can be fussy to reassemble, and you run the risk of losing the o-rings.
